Simple GTO Trainer Alternatives in 2026: GTO Drills That Run on Your Phone

Simple GTO Trainer is a Windows program that costs $199 for a twelve-month Pro license, and the company that builds it has not shipped an update to either of its two iPhone apps since 2023. What the trainer does well is play out real hands and tell you on the spot where you left the solver line and what the mistake cost in EV. If that's what you're after, GTO Gecko is the better buy in 2026, because it does that natively on iOS, Android, Apple Silicon Macs and in a browser for $149.99 a year. Below are six alternatives priced off each vendor's own site on August 22, 2026, and an honest read on which one fits which player.

Disclosure: we build GTO Gecko. Every price here links to the page we read it from, because these are all numbers you can check in about ninety seconds, and where a competitor does something we don't, it's in the table.

Tool	First-year cost	Platforms	What it is	Best for
Simple GTO Trainer (Pro)	$199/yr	Windows	Hand-playing trainer with real-time GTO feedback; imports SPF and Pio solves	Windows grinders who already own a solver
GTO Gecko (one format)	$149.99/yr (~$12.50/mo)	iOS, Android, macOS, web	Presolved preflop and postflop library plus four trainers and a leak finder	Players who study on the phone they already carry
GTO Gecko (all formats)	$239.99/yr (~$20/mo)	iOS, Android, macOS, web	Cash, MTT and Spin & Go in one subscription	Anyone playing more than one game type
GTO Wizard (Starter)	$468/yr ($39/mo billed annually)	Browser	The largest presolved library in the category, single bet size on Starter	Online players with a desk and a budget
GTOBase	$1,200/yr ($100/mo billed annually)	Browser, iOS	Simple Poker's own web viewer, trainer and hand-history analyzer	Spin & Go and heads-up specialists who want SPF solves in a browser
Postflop+	Free download, in-app purchases $4.99–$199.99	iOS, Android	Offline postflop drilling against presolved spots	Commuters and anyone studying without a connection
PioSOLVER Pro	€450 one-time, one year of updates	Windows	The solver engine itself, not a trainer	People who want to run their own solves
GTO+	$75 one-time	Windows	Cheapest way to own a postflop solver outright	Budget solvers who don't mind a tree builder

Two things jump out of that table. Simple GTO Trainer is not expensive by desktop standards; GTO Wizard's cheapest annual plan is more than twice the price. And it's the only trainer on the list that needs you to bring your own solutions.

What Simple GTO Trainer actually costs

Simple GTO Trainer sells one paid tier, Pro, in three lengths: $99 for three months, $149 for six, and $199 for twelve. There's also a free version with no time limit and a seven-day trial. The gap between them is the Core GTO Pack, which is the built-in set of solved spots. Free and Trial users don't get it; Pro users do.

That matters more than it sounds, because the trainer is a front end. Its own product page says it's built on the Simple Postflop engine, imports custom SPF solution files, and supports PioSolver files too. So the useful version of the product is Pro plus solutions, and solutions cost money separately: a Simple Postflop standalone license is $299, and the seven solution packs on Simple Poker's store run $149.99 to $349.99 each, with a $49 Spin & Go flop pack at the cheap end. Third-party cloud training packs and bot training are also listed as separate purchases at every license level, including Pro.

The other line to read before you buy: this is Windows software. Simple Poker's own Simple Postflop page tells Mac users to run it through Parallels or Boot Camp. And moving a Pro license to a new computer means deactivating it on the old one first. If that machine is dead or sold, their license page routes deactivation through Skype support.

None of that makes Simple GTO Trainer a bad product. It makes it a 2018 product, priced fairly for what it was when a solver license and a Windows tower were the entry fee for GTO study.

Simple Poker's phone apps stopped years ago

This is the part that decides the buying question for most people, and nobody writes it down, so here it is with dates.

Simple Software Solutions FZE LLC, the company in the footer of simplepoker.com, has published two iPhone apps. GTO Sensei launched in August 2020 as "your personal mobile poker trainer" and was last updated on May 12, 2021, at version 2.7. It sits at 1.9 stars from 9 ratings. GTOBase, the mobile companion to their web platform, was last updated on July 2, 2023, at version 2.09, and holds 4.0 stars from 19 ratings. Neither has a Google Play listing we could find on August 22, 2026. GTOBase's own FAQ says the mobile app is developed separately from the web version and "some of the functionality may differ."

Here's why that gap is worth money, from our own numbers rather than an opinion. Between May 1 and August 16, 2026, 96 GTO Gecko iOS installs came from someone typing a named rival's brand into App Store search. Forty-six of those 96, just under half, were searching for a Windows-only desktop tool: 43 for GTO+, 2 for PioSolver, 1 for "simple gto". People go to the App Store looking for desktop software by name, find nothing, and install whatever is actually there. Treat those as floors, not totals: 56% of our ad spend runs through Apple's Search Match with no keyword attached at all, so the real count is higher and we can't see it.

Try the drill that Simple GTO Trainer needs a Windows machine for — same idea, same instant EV feedback, on the phone in your pocket.

GTO Gecko: the trainer without the tower

GTO Gecko is a mobile GTO poker solver and trainer for Texas Hold'em, native on iPhone, iPad, Android, Apple Silicon Macs and the browser at play.gtogecko.com. It ships the two halves Simple GTO Trainer splits up: a presolved library and the drills that use it. The preflop explorer covers 315+ configurations across 6-max cash, 8-max ante and Spin & Go stacks; the postflop library runs flop, turn and river for cash, MTT and Spins. Four trainers sit on top: postflop, preflop quizzes, equity drills and mixed spots. Every rep is logged, so the leak finder can point at positional leaks and board textures you keep misplaying instead of you guessing.

Pricing is per game type: $24.99 a month or $149.99 a year for one format, $39.99 a month or $239.99 a year for all three. Elite adds ICM and the multiway trainer at $349.99 a year per format. It's free to download and 4.74 stars from 57 US App Store ratings, 4.9 from 1.06K Google Play reviews on 10K+ downloads.

Where we honestly lose to Simple GTO Trainer: you can't feed us your own solves. If you own Simple Postflop or PioSOLVER and your whole workflow is drilling spots you solved yourself, that's their product and not ours. Our library is our library.

GTO Wizard: the deepest library, at desk prices

GTO Wizard is the browser platform most players in the category have heard of, and it carries the largest presolved solution set of anything on this page: more formats, more bet-size trees, more study tooling around the solutions. If your study happens at a desk and the budget is there, it does more than the trainer you're replacing.

The cost is the catch. Starter is $49 a month, or $39 a month billed annually, which is $468 for a year and more than double Simple GTO Trainer Pro. Premium runs $99 a month, and the tiers climb from there to Ultra at $279. Note that gtowizard.com's pricing page now redirects into the app, so those figures come from our own last check and their public tier announcements rather than a page you can read logged out. We broke the full ladder down in GTO Wizard pricing, and the head-to-head against our app is in GTO Gecko vs GTO Wizard.

GTOBase: staying inside the Simple Poker family

GTOBase is Simple Poker's own web application: a strategy viewer, a trainer, and a hand-history analyzer that scores your played hands against GTO and flags the biggest EV mistakes. The solutions come from the same Simple Postflop and Simple Preflop Hold'em engines behind the desktop trainer, which makes it the natural move for someone who likes Simple Poker's solves and just wants out of a Windows install.

It is by far the most expensive option here. Their pricing panel lists $150 for one month, $400 for three ($133.33 a month) and $1,200 for a year ($100 a month), with a separate $75-a-month tier; prices vary by library, so check the one you actually want. The library skews to Spin & Go and heads-up hyper-turbo at 4–25bb, plus 8-max and 9-max MTTs with the major two-way postflop spots, an HU ante library and a free HU cash 100bb library. Six-max cash players should confirm coverage before paying for a year.

Postflop+: the offline drill app

Postflop+ from Crafty Wheel Studios is the other real mobile postflop trainer, and it does one thing we don't: it works fully offline once the spots are downloaded, which matters on planes and subways. It's free to download with in-app purchases from $4.99 to $199.99 on Google Play. Reviews split by platform in a way worth knowing about: 4.67 stars from 1,957 US App Store ratings against 3.7 from 2.31K Google Play reviews on 100K+ downloads.

It's a drilling app rather than a study platform, so there's no range browser to go read when the drill confuses you. Pair it with something that has one. We covered where it lands against the rest of the field in the best poker solver apps.

PioSOLVER and GTO+: when you wanted the engine, not the trainer

Plenty of people arrive at Simple GTO Trainer because they want solver output and the trainer was the friendly way in. If that's you, buy the engine directly.

PioSOLVER sells two editions, both one-time purchases with a year of updates and usable on two computers: Pro at €450 (postflop, up to 16 cores) and Edge at €800 (adds a heads-up preflop solver, up to 64 cores). GTO+ is the budget end at $75 for a license on one computer, $40 for a second, with all future updates included — the cheapest way to own a postflop solver outright, and cheaper than four months of Simple GTO Trainer Pro. Both are Windows programs, both hand you a tree builder and a wait, and neither drills you. If that trade appeals, our PioSolver alternatives post goes deeper on the desktop side, and how to use a poker solver covers the workflow.

Which one should you actually buy?

• You already own Simple Postflop or PioSOLVER and drill your own solves. Stay on Simple GTO Trainer. Nothing else on this page will play your solution files back at you.
• You study on a phone, or between tournament levels, or on a couch. GTO Gecko, $149.99 a year for one format. That's the whole reason we built it.
• You want the biggest library and study at a desk with budget to spare. GTO Wizard Starter at $468 a year, moving up if single-bet-size solutions start to bind.
• You're a Spin & Go or heads-up hyper specialist who trusts SPF solves. GTOBase, if you can stomach $1,200 a year.
• You mostly study without a connection. Postflop+, free to try, and buy only the packs you'll drill.
• You want to run your own solves on a budget. GTO+ at $75 one-time. It's the best value per dollar in the category and it's been that for years.

Open the range explorer in a browser and check the spot you got wrong last night before you commit to anything on this list.

What switching from Simple GTO Trainer costs you

You lose the ability to train on solutions you generated yourself. That's the real cost and it's not small if your study is built around custom trees, nodelocked ranges or exploitative sims you built in Simple Postflop. A presolved library answers the spots it was solved for, and no more.

You keep everything you learned. Frequencies don't change vendors. A 33% c-bet on a K-high rainbow board is a 33% c-bet on a K-high rainbow board whether the number came out of SPF, Pio or our library, and the difference between two accurate solvers on the same spot is smaller than the difference between your play and either of them. If that distinction is fuzzy, solver vs GTO trainer sorts out which tool does which job.

You gain the study sessions you were never going to sit down for. That's the honest pitch. The tower session you plan for Sunday happens maybe twice a month; the four minutes in a queue happen every day.

Simple GTO Trainer Alternatives FAQ

Is there a Simple GTO Trainer app for iPhone?

No. Simple GTO Trainer is Windows software. Simple Poker has published two iPhone apps — GTO Sensei, last updated May 2021, and GTOBase, last updated July 2023 — and neither is the trainer. For GTO drills native on iOS, GTO Gecko and Postflop+ are the two current options with 2026 updates.

Is Simple GTO Trainer free?

Partly. The free version has no time limit and lets you create and play custom drills and regulars plus the free beta starter content, but it excludes the Core GTO Pack. That pack comes with Pro, which is $99 for three months, $149 for six or $199 for twelve. A seven-day trial can be activated once per user and also excludes the Core GTO Pack.

Do I need Simple Postflop to use Simple GTO Trainer?

Not strictly — Pro includes the Core GTO Pack. But the trainer is built on the Simple Postflop engine and is designed around importing your own SPF solution files, and if you own SPF you can use its engine for live turn and river solving during training. PioSolver files are supported too. Without a solver license you're limited to the packs you buy.

What's the cheapest Simple GTO Trainer alternative?

GTO+ at $75 one-time if you want to own a solver, and Postflop+ if you want free drills with paid packs on top. Among subscriptions, GTO Gecko's single-format plan at $149.99 a year is the cheapest full library-plus-trainer on this page, and it undercuts Simple GTO Trainer Pro by $49 a year while running on hardware you already own.

Can I use a GTO trainer while I'm playing?

No. Querying a solver or a trainer mid-hand is real-time assistance and it's banned at every major site. All of these are study tools, used away from the table. We mapped out where the line sits in are poker solvers allowed.

The Bottom Line

Simple GTO Trainer earned its reputation, and for a Windows player with a solver license it still does a job nothing else does: it drills you on your own solutions. If that's your setup, keep it. Nobody should switch away from that.

For everyone else the shape of the product is the problem. It's a Windows install that expects you to bring solutions, sold by a company whose two mobile apps have been sitting untouched since 2021 and 2023. Our answer is the one we built: the library and the trainers in one app, on iOS, Android, Mac and web, $149.99 a year for a format and $239.99 for all three. Get it on iOS or Android and drill twenty spots tonight instead of booking a session you'll move to next weekend.
