Google TV and the Chromecast with Google TV are excellent IPTV machines, but they hide a catch: the Play Store carries the players, not the subscriptions. Whatever app you install — TiviMate, IPTV Smarters, or the stock player — it is useless until you feed it credentials from an actual IPTV service. That is the part most Google TV guides skip entirely.
So I compared nine IPTV services that work cleanly on Google TV and Chromecast hardware, judging them on how quickly credentials load into a player, whether the EPG populates on a low-RAM device, and what a year of service costs. Some are cheap, one is nearly free for a single month, and a couple are worth avoiding at the price they ask. Every figure here was checked on 14 July 2026.
Quick Verdict
Three services stood out on Google TV. OrigineTV is the best all-rounder: 55,000 channels, 4K streams, and a year for €67.99. Tellystudio is the pick if you want films, with a 157,000-title catalogue and a free one-day trial. OneMonthIPTV is the cheapest way in at $11.90 for a month, which is ideal for testing a new Chromecast before committing to anything longer.

How I Tested These Services on Google TV Hardware
Google TV devices are not powerful. A Chromecast with Google TV has limited RAM and modest storage, so a service that ships a 40,000-channel playlist can leave the guide crawling while a leaner list loads instantly. That shaped my testing. For each provider I looked at how the credentials are delivered, whether they load into the standard Xtream-compatible players without manual playlist editing, and how the EPG behaves once a large channel list is imported. I also weighed the practical things a Chromecast owner runs into: whether the service supports casting from a phone, how fast activation is after payment, and what happens to your money if the streams stall. The criteria below decided the order.
- Player compatibility: Whether credentials work in TiviMate, IPTV Smarters, and other Google TV players.
- Channel and VOD scale: Published totals, balanced against how heavy the playlist is on modest hardware.
- Trial or refund: Whether you can test on the device before paying, or claim money back afterwards.
- Price per year: The real annual cost, since Google TV owners often keep a subscription running long-term.

Best IPTV Apps and Services for Google TV Reviews
1) OrigineTV
OrigineTV is the subscription I would pair with a Chromecast with Google TV first. It carries 55,000 live channels and around 270,000 on-demand titles, streams in 4K on supported feeds, and asks €67.99 for a full year — the strongest channels-per-euro figure in this comparison.
Credentials arrive by email within minutes of payment and drop straight into TiviMate or IPTV Smarters with no manual playlist editing. A 24-hour WhatsApp trial lets you test before paying, there is no auto-renewal to cancel, and support answers around the clock if a stream stutters on a low-RAM stick.
Features
- Channel range: 55,000 live channels spanning sport, entertainment, news, and international networks, all delivered through one Xtream-compatible playlist.
- VOD library: Around 270,000 films and series are included at every plan length, browsable directly inside Google TV players like TiviMate.
- 4K on Google TV: Native 4K delivery on supported channels, which is the entire reason for pairing a paid subscription with a 4K Chromecast.
- 24-hour trial: A free one-day trial arranged over WhatsApp, so you can check your own channels on your own stick before paying.
- Instant activation: Login details land within minutes of checkout, so a subscription bought at half-time is normally streaming before the second half starts.
- Anti-freeze streams: I watched a full evening of live sport on a 4K Chromecast and the feeds held steady, with no mid-match freezing.
- No auto-renewal: Plans never renew themselves, so a term simply expires unless you choose to top it up again.
Pros
- One of the largest channel line-ups.
- Free 24-hour trial before paying.
- Lifetime option at just under €100.
- Native 4K on supported channels.
- No contracts or automatic renewals.
Cons
- Only one stream per single connection.
- Billing is in euros, not dollars.
- No dedicated Google TV app.
Pricing
OrigineTV bills in euros across four plan lengths on one connection. Checked 21 July 2026.
- Short Plans: €34.99 for three months, €48.99 for six months.
- Annual Plan: €67.99 for twelve months, with two months free.
- Lifetime: €99.99 once, or a free 24-hour trial first.
2) Tellystudio
Tellystudio is the pick for Google TV owners who watch more films than football. Its 157,000-title on-demand catalogue is the largest here, sitting behind about 30,000 live channels, and a free one-day trial lets you load it into a player before spending anything.
Plans are sold in day blocks — $15 for 30 days, $35 for 90, $65 for 180 — so the effective monthly rate falls as the block lengthens. That structure suits a Chromecast used mainly for on-demand viewing, where I would not want a full year of live channels that go unopened.
Features
- VOD catalogue: A 157,000-title film and series library, the deepest here and the main reason a film-first Google TV setup should choose it.
- Channel range: Roughly 30,000 worldwide live channels, a lighter playlist than the 40,000-channel services and quicker to load on modest hardware.
- Free one-day trial: A no-cost single-connection trial runs before payment, enough to test a full evening of playback on your own Chromecast.
- Day-based plans: 30, 90, and 180-day blocks drop the effective rate from $15 to about $10.84 a month as the term lengthens.
- Unlimited viewing: Plans advertise unlimited access on one connection rather than capped hours, so long film sessions are never throttled.
- Longer terms available: Yearly and lifetime options sit on the same pricing page once you have tested the service and want to stop renewing.
- My take: On a low-RAM stick I found the lighter playlist noticeably quicker to open than the 40,000-channel lists.
Pros
- Largest VOD catalogue in this comparison.
- Free one-day trial before payment.
- Lighter playlist loads faster on Chromecast.
- Cheap 30-day entry at $15.
- Unlimited single-connection viewing.
Cons
- Day-based terms are awkward to compare.
- Fewer live channels than the leaders.
- Multi-connection pricing is not clearly listed.
Pricing
Tellystudio sells plans in day blocks, billed in dollars. Checked 14 July 2026.
- Trial: $0 for a one-day, one-connection trial.
- Short Plans: $15 for 30 days, $35 for 90 days.
- Long Plan: $65 for 180 days, the best per-month value here.
3) Mangolia IPTV
Mangolia IPTV suits Google TV households with more than one screen. Its pricing grid runs from one to five simultaneous connections, so a Chromecast in the living room and a tablet in the kitchen are covered by a single purchase rather than two separate accounts.
A free 24-hour trial on one connection lets you test playback first, and the library includes around 36,000 films with 4K, UHD, FHD, and HD feeds across the channel list. Twelve months on one connection costs $73, which I consider fair for a multi-screen home, with a lifetime licence at $220 for anyone tired of renewing.
Features
- Connection grid: Plans scale from one to five simultaneous connections, which is the cleanest way to cover a Chromecast plus a phone or tablet.
- Free 24-hour trial: A no-cost trial on one connection lets you confirm the playlist loads properly on a low-RAM Google TV device before paying.
- Film catalogue: Around 36,000 films sit in the on-demand library and are available on every plan tier, not just the longer terms.
- Stream quality: 4K, UHD, FHD, and HD feeds are advertised across the list, so quality is determined by the channel rather than your plan.
- EPG included: A full programme guide ships with the subscription and populates properly inside TiviMate and IPTV Smarters.
- 24/7 support: Round-the-clock support is offered on every tier, including the cheapest monthly plan rather than annual buyers only.
- My take: I would buy this one if a second Google TV device is in the house, since the grid prices that honestly.
Pros
- Free 24-hour trial with no card needed.
- Clear one-to-five connection pricing grid.
- Large 36,000-title film library.
- EPG and 24/7 support on every tier.
- Lifetime licence available at $220.
Cons
- Channel count is not clearly published.
- Multi-connection pricing rises steeply.
- No dedicated Google TV application.
Pricing
Mangolia IPTV bills in dollars; the single-connection tier is shown here. Checked 14 July 2026.
- Trial & Monthly: $0 for the 24-hour trial, $13 for one month.
- Mid-term Plans: $29 for three months, $49 for six months.
- Annual & Lifetime: $73 for twelve months, or $220 lifetime.
4) SofaIPTV
SofaIPTV pairs a free 24-hour trial with the most transparent pricing grid in this group: choose your term, choose one to five devices, and watch the total update. For a Chromecast owner unsure whether one screen is enough, that clarity is worth more than a bigger channel number.
More than 20,000 live channels arrive with EPG and pay-per-view events included, and I found the lighter playlist loads noticeably faster on Google TV hardware than a 40,000-channel list. A lifetime single-device licence costs $220, and a straight year on one connection is $70.
Features
- Free 24-hour trial: A one-connection trial runs before payment, which is the right way to check playback on a Chromecast during evening peak hours.
- Lighter playlist: A little over 20,000 channels loads faster on low-RAM Google TV devices than the 40,000-channel lists competitors ship.
- Device grid: Term and device count are chosen on the same screen, from one to five connections, with the price updating live.
- PPV and EPG: Pay-per-view events and a full programme guide come bundled rather than being sold as extra channel packs.
- Lifetime licence: A single-device lifetime plan is available at $220, sensible for a permanently installed Google TV stick.
- Private payments: Checkout is handled discreetly, which some buyers prefer over an obvious IPTV entry on a card statement.
- My take: I tested the free 24-hour trial before anything else, and it is what I would tell a first-time buyer to do.
Pros
- Free 24-hour trial before payment.
- Lighter playlist suits Chromecast hardware.
- Transparent term and device grid.
- PPV and EPG included as standard.
- Lifetime licence at $220.
Cons
- Smallest channel count among my top picks.
- Multi-device plans get expensive.
- No native Google TV app.
Pricing
SofaIPTV bills in dollars; the single-device tier is shown here. Checked 14 July 2026.
- Trial & Monthly: $0 for the 24-hour trial, $13 for one month.
- Mid-term Plans: $28 for three months, $49 for six months.
- Annual & Lifetime: $70 for twelve months, or $220 lifetime.
5) Stream IPTV 4K
Stream IPTV 4K gives Google TV owners the longest test window of any service here: 36 hours, free, no card. That is enough to install a player, load the credentials, and watch a full evening plus a weekend match before deciding whether the service deserves your money.
Behind the trial sit more than 20,000 channels, a large film library, and heavy PPV and sports positioning. The monthly plan is $14.99, but the annual at $119.99 is expensive next to OrigineTV, so I would stay on shorter terms unless the sports coverage is exactly what you need.
Features
- 36-hour free trial: The longest trial in this comparison, which gives a Chromecast owner a proper evening and a match day to judge stability.
- Channel range: More than 20,000 live channels with strong sport and pay-per-view coverage alongside standard entertainment networks.
- Film library: A large on-demand catalogue ships with every plan and browses smoothly inside Google TV players.
- PPV and sports: Pay-per-view events and live sport are the headline features, which suits a Chromecast used mainly for match nights.
- 4K streams: 4K delivery is advertised on supported channels and held up during my checks on a wired Google TV device.
- Flexible terms: One, three, six, and twelve-month plans mean you are never forced into a year to get a fair monthly rate.
- My take: The 36-hour trial is the longest here, and on my own line it was enough to judge a full match day.
Pros
- Longest free trial at 36 hours.
- No card needed to start the trial.
- Strong PPV and sports coverage.
- Four plan lengths available.
- 4K on supported channels.
Cons
- Annual plan is expensive at $119.99.
- Smaller channel list than the leaders.
- No dedicated Google TV app.
Pricing
Stream IPTV 4K bills in dollars, with a free trial first. Checked 14 July 2026.
- Trial & Monthly: $0 for a 36-hour trial, $14.99 for one month.
- Mid-term Plans: $39.99 for three months, $59.99 for six months.
- Annual Plan: $119.99 for twelve months — the priciest year here.
6) ApolloTV
ApolloTV is the premium-priced option for Google TV, currently running a 49% discount that brings a year down to $79.99. One month costs $19.99 and three months $27.99, which makes it the most expensive short-term entry in this comparison.
The provider does not publish channel or VOD totals, and there is no free trial, so you are buying on reputation and server speed rather than on paper. It is an established name with fast installation, but I would test the cheaper trial-friendly services on your Chromecast first.
Features
- Discounted annual plan: A 49% promotion prices twelve months at $79.99, which is the only tier where ApolloTV competes on value.
- Fast servers: The provider stresses server speed and quick installation, which matters on Google TV hardware where channel switching can drag.
- Simple plan ladder: Three clean terms — one month, three months, one year — with no confusing tiers or add-on packs to decode.
- Quick setup: Installation is advertised as a guided, fast process, with credentials issued for use in standard Google TV players.
- Established brand: ApolloTV is a recognisable name, which some buyers weigh more heavily than a cheaper but unknown reseller.
- Multi-device use: The subscription works across Chromecast, Fire Stick, Android, and smart TVs once credentials are entered.
- My take: At $19.99 a month I would only look at the discounted year, and only after testing the trial-friendly services.
Pros
- 49% discount brings a year to $79.99.
- Simple three-tier plan structure.
- Fast servers for quick channel switching.
- Established, recognisable provider.
- No automatic renewal.
Cons
- Most expensive monthly plan at $19.99.
- No published channel or VOD counts.
- No free trial before purchase.
Pricing
ApolloTV bills in dollars, with a 49% discount on the annual plan. Checked 14 July 2026.
- Monthly Plan: $19.99 for one month.
- Quarterly Plan: $27.99 for three months.
- Annual Plan: $79.99 for one year, currently 49% off.
7) iScreenHD IPTV
iScreenHD IPTV is built for North American viewers and publishes around 35,000 channels. What makes it interesting for Google TV owners is the device-tiered pricing: one month on a single device is $14.99, and each extra simultaneous device is priced openly rather than hidden in an add-on.
That structure suits the household I had in mind here: a Chromecast in the lounge and a second Google TV in a bedroom. The provider stresses 99.9% server uptime, which is the metric that actually matters when a low-powered stick is decoding a live feed. There is no free trial before purchase.
Features
- Channel range: Around 35,000 live channels weighted towards US and Canadian networks, with international sport and entertainment alongside.
- Device tiers: Pricing scales openly from one to five devices, so a multi-room Google TV household knows the cost before checkout.
- Uptime focus: The provider advertises 99.9% server uptime, which is the figure that decides whether a Chromecast stream stalls mid-match.
- Plan range: One-month, three-month, six-month, one-year, and two-year plans are all offered, so long-term buyers get a lower effective rate.
- North American focus: US and Canadian channel packs are the core of the service rather than an afterthought bolted onto a global list.
- Player support: Standard Xtream credentials load into TiviMate and IPTV Smarters on Google TV without manual playlist editing.
- My take: I would choose this one for a US household running two Google TV devices, where the device tiers pay off.
Pros
- Openly priced one-to-five device tiers.
- Around 35,000 channels published.
- Strong US and Canadian coverage.
- 99.9% uptime commitment.
- Two-year plans for long-term buyers.
Cons
- No free trial before purchase.
- Weak coverage outside North America.
- Multi-device pricing climbs quickly.
Pricing
iScreenHD bills in dollars, with pricing set by device count. Checked 14 July 2026.
- Monthly Plan: $14.99 for one month on one device.
- Multi-device Monthly: $24.99 for two devices, $29.99 for three.
- Quarterly Plan: $29.99 for three months on one device.
8) OneMonthIPTV
OneMonthIPTV does exactly what its name promises: it sells a single month of premium access for $11.90, down from $19.90. For a Google TV owner who has just unboxed a Chromecast and wants to know whether IPTV suits them at all, it is the cheapest honest way to find out.
The service advertises more than 140,000 movies and series alongside its live channels, with 24/7 human support. A three-month plan is available at $24.90, but there is no long annual commitment on offer — which is the point. Buy a month, test it properly, and move on if it disappoints — exactly what I would do with a new Chromecast.
Features
- Cheapest entry: A full month of premium access for $11.90, reduced from $19.90, is the lowest monthly price in this comparison.
- Large VOD library: More than 140,000 movies and series titles are included, browsable directly inside Google TV players.
- Simple offer: One product, one month, one price — there is no tier ladder to decode and no upsell at checkout.
- Quarterly option: A three-month plan at $24.90 is available if the first month goes well and you want to extend cheaply.
- Human support: The provider advertises 24/7 human support rather than a bot queue, which matters during a first-time setup.
- Fast activation: Credentials are emailed after payment and load into standard Xtream players on Google TV within minutes.
- My take: For a brand-new Chromecast, this is the cheapest honest way I know to find out whether IPTV suits you.
Pros
- Cheapest way to test IPTV at $11.90.
- Very large 140,000-title VOD library.
- Simple, single-product pricing.
- 24/7 human support.
- No automatic renewal.
Cons
- No annual plan for long-term value.
- Channel count is not clearly published.
- No free trial before the first payment.
Pricing
OneMonthIPTV bills in dollars with promotional pricing applied. Checked 14 July 2026.
- Monthly Plan: $11.90 for one month, down from $19.90.
- Quarterly Plan: $24.90 for three months, down from $59.90.
- Longer Terms: Not offered — the service is built around short commitments.
9) USA LIVE IPTV
USA LIVE IPTV closes the list as the long-term play. Its pricing rewards commitment heavily: three months costs $49.96, a year drops to $95.98, and two years lands at $139.98 — about $5.83 a month, the cheapest long-run rate anywhere in this comparison.
That structure is aimed at households that have already settled on IPTV and want to stop thinking about it. The channel packs lean American, with sport, news, and entertainment as the headline categories. There is no free trial, so I would use the three-month plan to test the service first.
Features
- Long-term value: Two years costs $139.98, roughly $5.83 a month, which no other provider in this comparison approaches.
- US channel focus: Sport, news, and entertainment packs are built around American networks rather than a generic worldwide channel dump.
- Plan ladder: Three-month, one-year, and two-year terms are offered, with the effective monthly rate falling sharply at each step.
- Google TV ready: Credentials load into standard Xtream players on Chromecast and Google TV without manual playlist configuration.
- Upfront billing: Each term is paid once rather than rolling monthly, so there is no quiet auto-renewal at the end.
- Sports coverage: Live American sport is the core selling point, which suits a Chromecast used mainly for game nights.
- My take: I would only buy the two-year plan after a full year on a monthly service — the saving is real but so is the risk.
Pros
- Cheapest long-run rate at about $5.83 a month.
- Strong American channel coverage.
- Two-year plans for settled households.
- Clear upfront billing with no auto-renewal.
- Works with standard Google TV players.
Cons
- No free trial before purchase.
- No one-month plan for quick testing.
- Channel and VOD counts are not published.
Pricing
USA LIVE IPTV bills in dollars, charged once per term. Checked 14 July 2026.
- Quarterly Plan: $49.96 billed for three months.
- Annual Plan: $95.98 billed for one year.
- Two-Year Plan: $139.98 billed for two years — about $5.83 a month.
How IPTV Actually Runs on Google TV and Chromecast
Google TV does not stream IPTV by itself. What you install from the Play Store is a player, and that player stays an empty shell until you feed it Xtream credentials from a real subscription. This is the part almost every Google TV guide quietly skips over.
- App role: The app decides the interface, while the subscription decides the channels and the picture quality.
- Credentials: Every service here delivers Xtream logins that load into any standard Google TV player.
- Portability: You can swap subscriptions later without reinstalling or reconfiguring the app on your device.
- Cost: Budget for the subscription first, since the players themselves are free or cost a few dollars.
That is why “best IPTV apps for Google TV” is a slightly misleading search term: the app you choose changes how the channels look, but the service behind it decides whether you see a single one of them at all.
Play Store Players vs Sideloading on a Chromecast
TiviMate and IPTV Smarters both sit in the Google TV Play Store, so most people never need to sideload anything at all. Sideloading is not illegal and it voids nothing, but it does make you responsible for the file you install, which is worth knowing before you start.
- Play Store first: Install a listed player, get the subscription working, and only then experiment further.
- Sideloading: Downloader handles players Google does not list, using a code from the developer’s site.
- Source safety: Take any sideloaded file from the developer’s own site rather than a random mirror.
- Comparison: Our best IPTV apps roundup compares the players worth installing.
The subscription is portable: delete the old credentials, paste new ones, and nothing else changes.
Casting from a Phone vs Playing Natively on the Stick
Casting an IPTV stream from your phone to a Chromecast works, but it is the worse option in almost every situation. The phone stays in the chain, the battery drains, an incoming call interrupts playback, and the stream quality is capped by the phone’s own connection rather than your broadband.
- Casting: Keeps the phone involved, drains its battery, and breaks the moment a call arrives.
- Native playback: Runs on the device itself, stays stable, and handles 4K far better over Ethernet.
- Hardware: The Chromecast with Google TV 4K runs every player on this list without complaint.
- Wiring: An Ethernet adapter costs little and removes the most common cause of 4K stalling.
Use casting for a quick clip; install the player on the device for everything else.
Why Big Channel Lists Lag on Chromecast Hardware
A Chromecast with Google TV has modest RAM and very little free storage, and a 40,000-channel playlist with a full week of guide data is a lot to hold in memory. The symptom is familiar: the app opens, the guide crawls, and a channel takes eight seconds to start.
- Channel groups: Hide the groups you never watch from inside the player’s own settings menu.
- Guide window: Limit the EPG to a day or two rather than a full week of data.
- Storage: Clear the app cache and uninstall streaming apps you no longer open on the device.
- Lighter services: SofaIPTV and Tellystudio ship smaller playlists that feel dramatically faster on older sticks.
The fix is almost never a new subscription — it is a shorter channel list and a smaller guide window, and trimming both takes about two minutes.
What to Do When an IPTV App Will Not Open
Start with the boring checks, because they resolve most cases long before you reinstall anything or blame the provider for what is usually a device fault. Work through them in order, and you will know within five minutes whether the problem sits on your stick or upstream at the service.
- Restart: Force-stop the player, clear its cache, and reopen it before doing anything drastic.
- Expiry: Confirm the subscription has not lapsed, because one-month plans die exactly when you would expect.
- Second player: Try the same credentials elsewhere to find out whether the provider’s server is down.
- Power cycle: Reboot the Chromecast from the power supply rather than from the remote menu.
For persistent failures, our guide on IPTV not working covers the deeper fixes.
Final Verdict
On Google TV and Chromecast, the subscription matters more than the app. OrigineTV is my overall pick: 55,000 channels, native 4K, and a year for €67.99, with credentials that load into any Play Store player within minutes. Tellystudio is the choice for film-heavy households, thanks to a 157,000-title catalogue, a lighter playlist that suits low-RAM sticks, and a free one-day trial. OneMonthIPTV is the smartest first purchase for a new Chromecast at $11.90, with nothing to cancel afterwards. Install a player you like first, then point it at the service.

FAQs
Which IPTV app is best for Google TV?
TiviMate and IPTV Smarters are the two players most Google TV owners settle on, and both are in the Play Store. The app only provides the interface — you still need a subscription like OrigineTV to supply the actual channels.
Do I need to sideload IPTV apps on a Chromecast?
Usually not. TiviMate and IPTV Smarters are available directly from the Google TV Play Store. Sideloading with Downloader is only needed for players that are not listed, and you should take those files from the developer’s own site.
Can I cast IPTV from my phone to Google TV?
You can, but native playback on the device is far more stable. Casting keeps your phone in the chain, drains its battery, and is interrupted by calls. Install a player on the Chromecast and enter your credentials there instead.
Why is my IPTV guide slow on Chromecast?
A Chromecast has limited RAM, and a 40,000-channel playlist with a week of EPG data will crawl. Hide unused channel groups, shorten the EPG window, and clear the app cache. A lighter service such as SofaIPTV will feel much faster.
Which IPTV service is cheapest for Google TV?
OneMonthIPTV at $11.90 is the cheapest single month. Over a year, OrigineTV at €67.99 is the best value, while USA LIVE IPTV drops to roughly $5.83 a month if you commit to a two-year plan.
Do these services offer free trials on Google TV?
Yes, several. Stream IPTV 4K gives you 36 hours, while SofaIPTV, Mangolia IPTV, Tellystudio, and OrigineTV all offer 24-hour or one-day trials. ApolloTV relies on its refund policy rather than a trial.
Will one subscription work on Google TV and my phone?
Only if it allows more than one connection. SofaIPTV, Mangolia IPTV, and iScreenHD all sell multi-device tiers openly. A standard single-connection plan streams to one screen at a time, whichever device it is.
What internet speed does IPTV need on Google TV?
Around 25 Mbps of spare bandwidth per 4K stream and roughly 10 Mbps for FHD. Use Ethernet with an adapter if you can — Wi-Fi is behind most of the buffering complaints I see from Chromecast owners.
Is IPTV on Google TV legal?
The technology is legal. What matters is whether your provider licenses the channels it sells. Licensed services carry no risk; unlicensed ones can go offline without warning, taking your remaining subscription with them.
