Search "poker solver app" in the App Store and you get a wall of icons with no way to tell which ones actually solve anything. Some are full GTO engines. Some are chart viewers that have not been updated since 2019. The listings all promise the same thing, and none mention pricing traps, battery drain, or offline limits.
This guide covers the six options worth your screen space. Short version: GTO Gecko is the only app that puts a full presolved library, an on-device solver, and three trainers in one native app (disclosure: it is ours, and we will show our work). ThinkGTO builds polished single-purpose apps but splits them across seven subscriptions. DTO is the budget tournament pick. Lucid is the flat-price all-rounder. GTO Wizard, the desktop market leader, still ships no native mobile app at all. PokerSnowie has aged out.
What Can a Poker Solver App Actually Do on a Phone?
A modern poker solver app can browse millions of presolved GTO solutions, drill you with trainers that grade every decision against solver output, and solve custom spots directly on your phone's processor. What it cannot do is replace a desktop workstation for enormous custom trees with a dozen bet sizes per node or heavy nodelocking workflows.
That gap matters less than most players think. The phones shipping in 2026 carry more compute than the desktops that ran the first PioSolver sims in 2015. A flop spot with a sensible bet-size menu solves on-device in seconds. Pull up the button's c-betting strategy on K♠7♦2♣ while you wait to board a flight, and the answer you get is the same answer a desktop solver gives.
Where phone apps genuinely win is repetition. Nobody opens their desktop solver for a spare ten minutes; everybody opens their phone. Players who drill daily on mobile put in five to ten times more hands per week than players who study only at a desk. Volume of graded decisions, not raw solver horsepower, is what moves your win rate. If you are new to solver work entirely, start with our guide on how to use a poker solver and the basics of GTO poker.
The honest limits: no phone app today does deep custom nodelocking the way desktop Pio does, multiway trees beyond three players remain desktop territory, and a tiny screen is a bad place to compare twelve sizing options side by side.

Presolved Libraries vs On-Device Solving: Which Matters More?
For about 90% of study, the presolved library matters more. Presolved solutions are computed on server clusters at desktop-grade accuracy, so you get instant, exact answers for standard spots. On-device solving covers the other 10%: the weird stack depth, the strange sizing, the spot the library never anticipated.
A presolved library is an encyclopedia someone already wrote with industrial hardware. On-device solving is a calculator you carry. You want both, because they fail in opposite directions: the encyclopedia is exact but finite, the calculator is infinite but slower and forced to simplify big trees.
Most apps on this list pick one side. DTO and GTO Wizard's mobile experience are library-only. ThinkGTO splits the two functions into separate paid apps. GTO Gecko and Lucid ship both in one product. When you evaluate any poker solver app, ask two questions: how big is the library, and what happens when my spot is not in it?
One more distinction worth money: multiway solutions. Almost every library on the market is heads-up only after the flop. True 3-way postflop solutions are rare because they are brutally expensive to compute, yet live and soft online pools are full of multiway pots. GTO Gecko ships true 3-way postflop solutions; among major competitors, only GTO Wizard offers comparable multiway coverage, and theirs is gated behind upper tiers.
The 6 Best Poker Solver Apps in 2026
We judged each app on five things: whether it is genuinely native on iOS and Android, library depth, what you can solve yourself, trainer quality, and what a year of real usage costs. Here is the field, as of June 2026, with each app's honest best use case.
| App | Native mobile app? | Best for |
|---|---|---|
| GTO Gecko | Yes (iOS, Android, macOS, web) | All-in-one solver + trainer study |
| ThinkGTO suite | Yes (7 separate apps) | Single-purpose drilling |
| DTO Poker | Yes | Budget MTT training |
| GTO Wizard | No (browser web app) | Desktop-first pros |
| Lucid GTO | Yes | Flat-price cross-platform value |
| PokerSnowie | Dated companion apps | Legacy users only |
1. GTO Gecko — Best All-in-One Poker Solver App
Full disclosure: GTO Gecko is our product, so read this section with that in mind. Every claim below is checkable in five minutes on the free tier, no credit card required.
GTO Gecko is a native app on iOS, Android, and macOS, plus a web app at play.gtogecko.com. One subscription covers all of them, with progress synced, so a trainer session on the bus continues on your laptop at home. The library is massive: preflop ranges and postflop solutions for Cash (including straddle and ante tables), MTT, and Spin & Go, with true 3-way multiway postflop solutions that almost nobody else in the market offers. When a spot is not in the library, a built-in on-device solver handles custom spots.
The training side is where it separates from chart viewers. Three trainers (preflop, postflop, and full-hand) grade you with an ELO rating and adaptively re-serve the spots you misplay until you stop misplaying them. A machine-learning explainability layer breaks down WHY the solver action is right in plain English using SHAP factors, instead of leaving you to reverse-engineer frequencies. A statistics suite tracks per-street accuracy, position and pot-type leaks, and hand review with replay, plus comparison against the player pool. Tournament players get ICM range compare, and ICM-aware MTT solutions are available in the Elite tiers; our ICM strategy guide covers why that matters near a bubble.
Pricing, as of June 2026: a single format (Cash, MTT, or Spin & Go) runs $24.99/month or $149.99/year (about $12.50/month effective). All-access to all three formats is $39.99/month or $239.99/year (about $20/month effective). Quarterly billing sits in between. The permanent free tier includes the full preflop range library to browse, daily free trainer hands, and free web tools. It holds a 4.8-star rating across 595+ app-store ratings, with 22,500+ players in 175 territories.
What it does not do: nodelocking, and the on-device solver will not chew through a 200-node custom tree the way a desktop rig does. PLO lives in a separate sister app, PLO Edge, which packs a PLO preflop solver, preflop trainer, and postflop trainer into one flat monthly price (no postflop solver there). Get GTO Gecko on the App Store, on Google Play, or browse the free preflop library on the web right now.
2. ThinkGTO Suite — Polished Apps, Fragmented Stack
ThinkGTO (by Crafty Wheel) is the most prolific mobile-first poker developer, with seven separate apps on iOS and Android: Preflop+, Postflop+, Solver+, GTO Ranges+, PLO+, the free Battle+, and Tracker+. Each one is genuinely well built. Postflop+ in particular is a smooth trainer with ELO tracking, and the apps feel fast and native because they are.
The catch is the business model. Preflop work, postflop training, and solver browsing are three different apps with three different subscriptions. As of June 2026, Preflop+ runs $9.99/month, Postflop+ $14.99/month, and Solver+ $19.99/month. Stack those three to approximate what a single all-in-one app does and you are at $44.97/month, more than GTO Gecko's all-access tier, with your progress and stats scattered across three icons that do not talk to each other. Lifetime purchases exist (Preflop+ at $129.99, Postflop+ at $199.99), which is a genuinely rare and fair option if you are certain you only ever need one narrow tool.
There is also no deep web or desktop app, so everything you build stays on your phone. Recommended for: players who want exactly one job done well, like push/fold drilling from Preflop+ alongside our preflop opening charts, and players who hate subscriptions enough to pay lifetime prices.
3. DTO Poker — Best Budget MTT Trainer
DTO is a trainer first and a solver browser second, built around tournament poker. The drilling experience is excellent: clean, fast, and focused on the MTT spots that actually come up. There is a real free tier, and the entry Grinder plan costs $9.99/month as of June 2026, the cheapest paid on-ramp on this list.
Read the tier table before you buy, though. Grinder gives you basic right/wrong evaluation with no EV-loss numbers and no optimal frequencies; the feedback that makes solver training valuable starts at the High Roller tier, $29.99/month. Full range viewing, ICM, and heads-up scenarios require Super High Roller at $99.99/month. So the honest price for serious study is $29.99, not $9.99. A DTO Cash product exists now, but the depth and the DNA are tournaments, and there is no PLO at all.
Recommended for: MTT grinders on a budget who mainly want reps, not deep dives. We cover the tier traps and trainer quality in detail in our full DTO Poker review.
4. GTO Wizard — Huge Library, No Native App
GTO Wizard is the market leader on desktop, and that is earned: the biggest solution library in poker, an AI solver, nodelocking, PLO support, and multiway spots. If you study primarily at a desk and money is not the constraint, it is a serious option, which is why we wrote a full GTO Gecko vs GTO Wizard comparison.
On mobile, the story is different. There is no GTO Wizard app in the App Store or on Google Play. Their own help docs state it plainly: "There is no dedicated iPhone/Android app," and they instruct you to add the website to your home screen as a progressive web app. That means a browser tab wearing an icon: no offline access, no native performance, and a desktop-density interface squeezed onto a phone. For a product at this price, the absence is notable.
About that price: as of June 2026, Starter begins at $39/month, Premium runs roughly $99/month, Elite sits in the $129–$199/month band, and the Ultra tier is $279/month at its early-bird rate. New-subscriber prices for Premium and Elite rose another $10–$20/month on March 31, 2026, a move that drew predictable heat on the forums. The full tier-by-tier math is in our GTO Wizard pricing breakdown. Recommended for: professionals who live in the desktop ecosystem and treat mobile as an occasional range check.
5. Lucid GTO — Best Flat-Price Cross-Platform Option
Lucid, backed by Doug Polk and the Upswing Poker camp, gets distribution right: real apps on iOS and Android plus Windows, Mac, Linux, and web, all under one subscription. Pricing is refreshingly simple as of June 2026: a free plan, then Pro at $49/month or $490/year. No tier ladder, no feature matrix to decode.
The product leans on presolved "Cloud Sims" and a capable trainer, and for NLHE cash players it covers the standard study loop well. The gaps: no PLO, and ICM has been explicitly deprioritized, which makes it a hard recommendation for serious tournament players. The trainer also lacks the adaptive re-serving and explainability layers that turn mistakes into fixed leaks rather than logged ones.
Recommended for: cash-game players who want one flat price across every device they own and do not need tournament tooling.
6. PokerSnowie — The Aging Neural Net
PokerSnowie deserves respect as a pioneer: it was teaching balanced poker years before solvers went mainstream. But it is a neural network trained against itself, not a true solver, and its recommendations diverge from solver baselines often enough that its accuracy has been questioned on training forums for years.
The mobile situation seals it. The iOS companion apps are ancient (the postflop app was last updated in 2019), and the main product is desktop software at $229.95/year for the Pro plan as of June 2026. For that money in 2026 you can get an actual solver library, an on-device solver, and modern trainers. Recommended for: existing subscribers with years of hand history in it; everyone else should read our full PokerSnowie review before paying.
How Much Do Poker Solver Apps Cost in 2026?
Real-world prices run from $9.99/month for an entry trainer tier to $279+/month for top desktop plans. The number that matters is price per feature you will actually use: a cheap app that gates EV feedback, or three polished apps that each do one thing, can cost more than one complete platform. All prices below are as of June 2026.
| App | Monthly price | What that buys |
|---|---|---|
| GTO Gecko | $24.99 (one format) / $39.99 (all-access); $149.99–$239.99 per year | Presolved library incl. 3-way spots, on-device solver, 3 trainers, stats, all platforms |
| ThinkGTO (3-app stack) | $44.97 ($9.99 + $14.99 + $19.99) | Preflop+ charts, Postflop+ trainer, Solver+ browser — three separate apps |
| DTO Poker | $9.99–$99.99 | MTT trainer; EV-loss feedback starts at the $29.99 tier |
| GTO Wizard | $39–$279+ | Deepest desktop library + AI solver; mobile is a browser shortcut |
| Lucid GTO | $49 (or $490/year) | Cloud sims + trainer on every platform; no PLO, ICM deprioritized |
| PokerSnowie | $229.95/year | Neural-net training advice, dated mobile apps, not a true solver |
Two patterns jump out. First, fragmentation is expensive: ThinkGTO's per-app pricing looks cheap until you need preflop, postflop, and a solver, at which point one all-in-one subscription wins on both price and workflow. Second, the floor price rarely buys the product you imagine; DTO's $9.99 tier withholds the EV numbers, and GTO Wizard's $39 Starter is a slice of the library the reviews rave about.
Battery, Offline Use, and Other Things Store Listings Skip
Browsing presolved solutions costs almost no battery because the heavy math already happened on a server. On-device solving works your phone's CPU hard, so expect warmth and real battery draw on long custom solves. Offline access depends entirely on architecture: native apps can cache data locally, while browser-based web apps need a connection.
This is the practical case against the progressive-web-app approach. A PWA is a website; lose signal in a casino basement or on a flight and your study session is over. Native apps keep cached ranges and downloaded content available, and an on-device solver is fully self-contained: the spot is computed on your hardware with nothing uploaded, which also means it works at 35,000 feet.
A few more things worth knowing before you subscribe. Cross-device sync is a feature, not a given: ThinkGTO progress lives and dies on your phone, while GTO Gecko and Lucid carry it across devices. Streaming a large solution library eats mobile data, so check what an app caches. On any app with an on-device solver, save the monster trees for when you are plugged in.
Which Poker Solver App Should You Download?
Pick by player type, not by ranking. All-in-one study on phone, tablet, and desktop: GTO Gecko. One narrow tool with a lifetime price: ThinkGTO. Cheapest MTT reps: DTO. Flat-price cash-game study everywhere: Lucid. Desktop-first professional workflow: GTO Wizard, accepting there is no real mobile app.
If you are still unsure, the zero-risk move is to start free. GTO Gecko's free tier includes the complete preflop range library and daily trainer hands with no credit card, DTO and Lucid both keep functional free plans, and our roundup of free GTO resources lists more. Spend a week drilling on whichever free tier fits your format, then pay for the one you actually opened every day.
Ready to test the all-in-one approach? Start with the free preflop library and daily trainer hands on GTO Gecko, or grab the native app from the App Store or Google Play.
Poker Solver App FAQ
Is there a real GTO solver app for iPhone?
Yes. GTO Gecko runs a full solver natively on iPhone alongside its presolved library, and ThinkGTO's Solver+ offers presolved board browsing. Lucid ships a native iOS trainer backed by cloud sims. GTO Wizard does not have an iPhone app; it runs as a website you pin to your home screen.
Can you run a poker solver on Android?
You can. GTO Gecko's Android app includes the same on-device solver and presolved library as the iOS version, and DTO, Lucid, and the ThinkGTO apps all ship native Android builds. Modern Android hardware solves single-flop spots with a reasonable bet-size menu in seconds.
What is the best free poker solver app?
GTO Gecko's free tier is the most complete: the entire preflop range library plus daily free trainer hands, permanently, with no credit card. DTO's free tier offers presolved scenario browsing, Lucid has a free plan, and ThinkGTO's Battle+ is a fully free GTO puzzle game.
Do poker solver apps work offline?
Native apps with cached content or on-device solving do; browser-based tools do not. An on-device solver computes everything locally, so it works in airplane mode. GTO Wizard's mobile experience is a progressive web app and needs an internet connection, which matters on flights and in poor-signal card rooms.
Are poker solver apps legal to use?
Studying with a solver away from the table is legal and universally accepted; it is how nearly every winning player trains now. Using any solver or chart app while playing online is real-time assistance, which almost every poker site bans and punishes with confiscation or closure. Study between sessions, never during them.
How accurate are mobile poker solvers compared to desktop?
Presolved solutions on mobile are exactly as accurate as desktop output because they were computed on server hardware; your phone is just the viewer. On-device solving uses simplified bet trees, so strategies can differ slightly from an exhaustive desktop sim, but for practical study the EV differences are marginal.
