The short answer

A preflop chart app stores solved starting-hand ranges on your phone so you can check the right play by position, stack depth and action without opening a desktop solver. Seven are worth knowing in August 2026, and they split into viewers that show you a range and trainers that make you play it and then tell you what the mistakes cost.

GTO Preflop is the one we’d put on your phone: 11,385 solved decision points across cash, tournaments and Spin & Go, with a trainer that grades every decision in EV loss. Preflop+ at $129.99 once is the best value here if all you want is push/fold charts plus math drills. GTO Poker Ranges by Red Chip ($99/yr) wins if you want exploitative ranges beside the GTO ones. CLP Poker Preflop Range Charts costs nothing and is genuinely good for live 9-handed cash. The other three have large followings and specific gaps worth knowing about first.

Note:

Full disclosure: GTO Preflop is our app. Every rating, price, platform and update date below was read off the vendor’s own store listing or website on August 21, 2026. Where a rival does something we don’t do, it’s on the page.

How we judged them

  1. Does the library go past opening ranges? Raise-first-in is the easy part. What happens when someone 3-bets you is where the money is.
  2. Does anything grade you? A chart tells you the answer. It can’t tell you that you’ve been folding AJo on the button for two years.
  3. Is the price on the page? Two of these seven publish no price anywhere public.
  4. Is it maintained on your platform? Two are effectively one-platform products, and one hasn’t shipped an update since 2023.
  5. Does it cover your game? Live 9-handed cash, online 6-max and 12bb tournament poker need three different sets of charts.

Why chart depth is the thing to check

Preflop is the only street you play every hand. Flop, turn and river decisions come round once or twice an orbit; the preflop decision arrives 100% of the time, which is why Upswing Poker names loose preflop play as the top leak among losing players and says no amount of postflop skill fixes a bad preflop strategy.

That’s the case for owning a chart app, and also the case for checking how deep the charts go before you pay. Our own solve database is a fair yardstick: 11,385 decision points across 503 scenario files, where opening ranges are one of three action levels, alongside facing-a-raise and facing-a-3-bet nodes. An app that ships one opening chart per position is showing you a slice of that. Stack depth widens it again.

Stack depths solved in GTO Preflop by game type: tournaments at 14 depths from 3 to 100bb, Spin and Go at 13 even depths from 2 to 34bb plus 418 asymmetric stack combinations, cash at 50, 100 and 200bb

The tournament row catches people out. A chart built for 100bb cash tells you nothing useful at 12 big blinds, where the solved opening size collapses to a 2bb min-raise, or at 6, where every opening action in the tree is a jam.

Tip:

Find your own gap in ten minutes: open GTO Preflop and run twenty trainer hands at the stack depth you actually play. The EV loss number at the end is the honest version of “I know my ranges”.

1. GTO Preflop — the deepest chart library on a phone

GTO Preflop is a preflop solver library and trainer for iPhone, iPad and Android. Everything is solved before you download it, so you browse a finished solution instead of waiting on a calculation: 11,385 decision points, 1,924,065 hand-specific strategies, 503 scenario files.

Coverage is why it’s first. Cash runs 50bb and 100bb raked plus 100bb and 200bb with a straddle, heads-up through 8-handed. Tournament ChipEV runs 14 depths from 3bb to 100bb at a standard 12.5% ante, with ICM and knockout nodes on top. Spin & Go gets 13 even depths from 2bb to 34bb plus 418 asymmetrical three-player stack combinations down to 1.5bb, which is what real spin stacks look like after the first hand. Nine positions, 169 starting hands, three action levels deep.

The trainer is the part a viewer can’t copy. It deals tournament spots from 3 to 12 big blinds and cash spots from 50 to 200, grades each decision against the solution, and reports EV loss per 100 hands with an ELO rating attached. You stop guessing whether you know a range and start seeing what it costs when you don’t.

Real limits: depths are a fixed grid, so at 7.3 big blinds you read the 8bb solve; the trainer doesn’t cover Spin & Go or depths above 12bb; ICM is one 10bb three-handed scenario, so bubble work belongs to a dedicated ICM tool; and the multiway explorer needs a connection.

Free to download, $19.99 a month or $119.99 a year, with a $7.99 weekly option. We run pricing experiments, so some users see different numbers. It holds 4.8 across 240 US App Store ratings and 4.6 across 3,180 Google Play reviews, on 100,000+ Android downloads.

2. Preflop+ — the best value if push/fold is your game

Preflop+ from Crafty Wheel Studios is the strongest chart-first app here, and pricing is the reason: $9.99 a month, $79.99 a year, or $129.99 once for lifetime access. Nothing else on this page sells a permanent licence. If Nash charts plus drills are all you need, buy that and stop reading.

You get shove/fold charts with the exact EV of each hand attached, five training drills, a full run of calculators (pot odds, combinatorics, equity), and a hands recorder that logs in chips or dollars rather than only big blinds. All of it works offline, which matters in a card room basement. It carries 4.6 across roughly 1,000 US App Store ratings and 4.1 across 2,570 Google Play reviews, on version 25.9 from August 10.

The limitation is scope, not quality. Preflop+ is built around the short-stack jam game and the math around it; the deep-stack opening, 3-bet and 4-bet tree is a separate app from the same studio, GTO Ranges+, so covering both costs two purchases. Our push/fold comparison goes deeper on where Nash charts stop being the right model.

3. Preflop Wizard — the biggest following, the least visible price

Heater LLC’s app, listed as “GTO Preflop Wizard Poker AI” on the App Store and “GTO Poker AI: Preflop Wizard” on Google Play, has the largest iOS following in this category at 4.8 stars across 3,400 ratings. The company’s site claims 175,000+ downloads, more than a million hands trained, 100+ GTO charts and 50,000+ unique spots.

The pitch is a daily AI-generated quiz aimed at whatever you keep getting wrong, plus adaptive practice, custom ranges, offline drilling, progress tracking and leaderboards. Training-first rather than lookup-first, and the loop is the right idea.

Two things to know. It’s an iPhone app, not built for iPad, and the Android version is far smaller at 4.4 stars across 557 reviews. More importantly, no price appears on the App Store listing, the Play listing or the company’s website. You install it, work through the funnel, and find out at the paywall. We’d rather a competitor beat us on price in public than hide the number.

4. GTO Poker Ranges by Red Chip — GTO next to exploitative

Red Chip Poker’s app does something none of the others do: it puts exploitative ranges beside the GTO ones and lets you flip between them by opponent tightness. For a live player facing a table of nits, that’s more actionable than a solver baseline.

The paid tier covers GTO 6-max, exploitative 6-max, exploitative and GTO live cash, and GTO tournament ranges, with favourites and offline access, for $12.99 a month or $99 a year. Desktop access is listed as coming. The free tier is open raising ranges only, which is thin — one action level and nothing else.

The catch is scale. It holds 4.1 across 12 App Store ratings and 3.9 across 44 Google Play reviews, so there’s very little user signal to read, and there’s no trainer or grading. If James “SplitSuit” Sweeney’s range work is the framework you already study, $99 a year buys his charts in your pocket. If it isn’t, you’re renting a lookup table.

5. CLP Poker Preflop Range Charts — free, and the right shape for live cash

Crush Live Poker’s chart app is free with no in-app purchases at all, and for a live 9-handed cash player it’s the best zero-dollar option here. It ships opening ranges from every position at 100bb and 200bb, the two depths that actually occur in a live game, plus opponent archetypes so you can shift the range by table type, and a dark mode for card rooms. It sits at 5.0 across 50 App Store ratings.

Ranges built by a live-focused coaching team for 9-handed play really are different from a 6-max online chart set, and most of this category ignores that gap.

The boundaries are sharp. It’s opening ranges — the app’s own feature list stops there, so facing a 3-bet you’re on your own. Nothing tournament-related, nothing short-stacked, no training. The iOS build needs iOS 18 or later, and the Android version is new enough that Google Play still shows it under 100+ downloads.

6. GTO Preflop – Texas Hold’em by AppBlue — the name collision

This one needs flagging because of the name. AppBlue’s “GTO Preflop – Texas Hold’em” is a different app from ours, by a different company, and it’s popular: 4.9 stars across 2,484 App Store ratings. If you searched for us and landed there, that’s why.

The idea is decent. Instead of showing charts it deals you preflop situations to play out and gives quick feedback, on the theory that playing beats staring at a table. Free to download with in-app purchases whose prices aren’t published, iPhone only, no Android version.

The published detail is where it thins. The store listing describes “various situations” without naming a single format, stack depth or table size, and the first reviews Apple shows on the page ask for exactly that: adjustable stack sizes and player counts, and 4-bet ranges. For one general baseline it clearly works for a lot of people. If you need your charts to match the game you’re in, the specification has to be published before it can be checked.

7. Upswing Poker’s charts — good ranges, awkward delivery

Upswing has the most widely quoted preflop charts in poker, from Doug Polk and Ryan Fee, and two ways to reach them on a phone. Neither is quite an app in 2026.

The Upswing Poker Chart Viewer on Google Play holds 240+ charts across online cash, live and MTT as a companion to the Upswing Lab. It’s rated 3.6 across 68 reviews, and its last update is dated August 21, 2023 — three years ago to the day as we publish this. There’s no equivalent on the US App Store; searching Apple’s catalogue for it on August 21, 2026 returns nothing from Upswing.

Preflop Prodigy is the replacement, and it’s a web app rather than a native one: mobile-first, loads on iOS, Android, Windows and Mac, and Upswing’s own page describes it as free for now with an account. Coverage is online cash 6-max, live cash 9-handed and tournaments at three stack depths, with facing-a-3-bet and 4-bet spots included. What you accept is a browser tab with no offline mode, no training and no EV feedback.

What about GTO Wizard?

GTO Wizard is the biggest name in GTO study and it does have preflop charts, but it isn’t a preflop chart app: it’s a full solver platform with postflop trees, and the phone experience wraps that. It’s also several times the price of anything here, and you can’t see the pricing without an account. We wrote a full head-to-head on GTO Wizard versus GTO Preflop. Short version: if you want postflop, pay for GTO Wizard. If preflop is the problem, you’re overbuying.

Check the platform before you commit

This category is bad at staying consistent across iOS and Android. Several of these apps are one-platform products with a neglected port on the other side, and store ratings make that visible.

Grouped bar chart comparing iOS and Android rating counts for six preflop chart apps, showing GTO Preflop with 240 iOS and 3,180 Android ratings while Preflop Wizard has 3,387 iOS and 557 Android

AppBlue’s app doesn’t exist on Android at all, and Upswing’s viewer doesn’t exist on iOS. We’re the opposite shape from Preflop Wizard: 3,180 Google Play reviews against 240 US App Store ratings, so on Android we have the larger user base and on iPhone they do. Rating counts measure attention, not chart depth — but a small count on your platform usually means fewer bug fixes for your device.

Which one should you pick?

  • Tournaments or spins: GTO Preflop. Nothing else covers 3bb to 100bb with asymmetric stacks, and nothing else grades your play at those depths.
  • Spend once, never again: Preflop+ at $129.99. Learn the jam game properly and skip the subscriptions.
  • Live 9-handed cash only: start with CLP’s free app, and add something with a 3-bet tree when you notice the gap.
  • Already studying Red Chip material: GTO Poker Ranges at $99/yr keeps you inside that framework, exploitative ranges included.
  • Free charts from a famous name: Preflop Prodigy in a browser tab.
  • A daily quiz, and you don’t mind an undisclosed price: Preflop Wizard.

One thing to take away: the app that shows you a range is not the app that fixes your range. Look up what you don’t know, then go and be tested on it. Our starting hands chart is where to see the baseline, and the position guide covers why the same hand is a fold and a raise two seats apart.

Preflop chart apps: FAQ

What is a preflop chart app?

A preflop chart app is a mobile app that stores precomputed starting-hand ranges and lets you look up the correct action by position, stack depth and what’s happened in front of you. The better ones also cover facing a raise and facing a 3-bet, and a few add a trainer that deals you spots and scores your decisions.

Is there a free preflop chart app?

Yes. CLP Poker Preflop Range Charts is free with no in-app purchases, and Upswing’s Preflop Prodigy is free with an account. Red Chip’s app has a free tier limited to opening ranges. GTO Preflop, Preflop+, Preflop Wizard and AppBlue’s app are free to download with paid content inside.

Do preflop chart apps work offline?

Some do. Preflop+ states that everything works with no internet connection, and Red Chip lists offline access on its paid tier. GTO Preflop keeps its core range files on the device, though the multiway explorer needs a connection. Preflop Prodigy is a web app, so it needs one.

Which preflop chart app is best for tournaments?

GTO Preflop, on coverage: 14 solved stack depths from 3bb to 100bb with antes, plus knockout and ICM nodes and 418 asymmetric spin configurations. Preflop+ is the value pick if your tournament study is push/fold only. For deep ICM work on the bubble, a dedicated ICM tool still beats every phone app, ours included.

Are preflop charts allowed while I’m playing online?

It depends on the site. Most operators separate static reference material from real-time assistance software, and several ban both during play. Read your poker room’s RTA policy before you use any of these apps at the table.

What’s the difference between a preflop chart app and a solver?

A solver computes a strategy for a spot you define, which takes time and usually a desktop. A chart app ships strategies that were already solved, so lookup is instant on a phone. GTO Preflop is the second kind, which is how a phone holds 1.9 million hand-specific strategies and returns one in a tap.
