Simple GTO Trainer Review: Drill Your Own GTO Solutions

This review is based on official product information from SimplePoker and published third-party sources, verified as of 18 October 2026. No hands-on testing was performed for this report.

Review summary

Simple GTO Trainer is a drill-based GTO (Game Theory Optimal) training program from SimplePoker. Instead of calculating strategies itself, it puts you in poker scenarios — from its own pre-built drills or from solution files you import from other solvers — and gives you instant feedback on whether your play matches GTO.

It fills a specific gap in the study stack: solvers tell you the answer, and a trainer makes the answer automatic. Its defining feature is that import workflow — you are not locked into one product’s solutions, which makes it a flexible companion to whichever solver you already use.

It is a Windows desktop program (no macOS or Linux), and the current generation’s licence is period-based rather than a lifetime purchase — a 2026 third-party listing shows a $199 twelve-month Pro licence, so confirm current pricing on the official site.

Verdict: one of the more flexible GTO trainers on the market, especially if you already run a solver and want your solutions to become habits.

What is Simple GTO Trainer?

Start with the solver/trainer distinction, because it defines the product. A solver is a heavy calculation engine that works out the mathematically balanced (GTO) way to play a spot. A trainer is the opposite machine: it deals you the spot, you make the call, and it scores you against the correct answer.

Simple GTO Trainer is that second machine. You play real poker hands and customised drills, and the software gives instant feedback on whether your action matches GTO strategy. A range, for those new to the terms, is the set of hands a player is expected to hold in a situation; a drill is a repeated exercise built around specific ranges and boards.

One clarification for readers arriving from search: this is not the former “GTO Trainer” brand at gto-trainer.com, which no longer appears operational. Simple GTO Trainer is a current product from SimplePoker, the developer behind the Simple Postflop solver and the wider SimplePoker family (Simple 3-way, Simple Nash, GTOBase, GTO Sensei, Simple Omaha and others).

The workflow that makes it interesting: you can use the built-in pre-built drills, or import your own GTO solution files and turn your solver work into a practice session. The trainer is the bridge between “I solved this spot” and “I now play this spot correctly under pressure”.

Who should use it?

Beginners The pre-built drills are a structured introduction to GTO-style decision making. The caution: GTO feedback is unforgiving, and without the underlying theory, “the solver said so” is a thin teacher. It works best once you understand why a balanced strategy makes sense.

Intermediate players The primary audience. You have learned that ranges matter, you have some solver exposure, and your problem is consistency — the gap between knowing a frequency and executing it at the table. Drilling is exactly how that gap closes.

Advanced players and coaches The value is customisation: run your solver (PioSolver, GTO+, Simple Postflop and others), export the solutions, import them here, and drill the precise spots you are working on. For coaches, it is a way to put a shared, repeatable practice environment in front of a student.

Cash and tournament players The drills cover No-Limit Hold’em scenarios relevant to both; nothing here is tournament-ICM specific (that is what ICMIZER 3 is for).

Main features

Pre-built training drills A library of ready-made GTO scenarios to start with immediately — no solver ownership required to benefit from the basics.

Custom solution file import The headline feature: load GTO solution files you have created (or obtained) in other solvers and turn them into playable training. Your study output becomes your practice input, which most closed trainer ecosystems do not let you do.

Instant feedback After each action, the trainer scores you against the GTO strategy for the spot — not just “right/wrong” but where your play deviated from the balanced frequencies. That immediate correction is the learning mechanism.

Limitations It does not solve: no new strategies are generated inside the trainer. Mobile support is effectively absent — the SimplePoker family has shipped iPhone apps before, but a 2026 third-party review notes no meaningful updates to them since 2023, so treat the desktop program as the product. Windows only.

Ease of use

The day-to-day experience is simple: start a drill, play the hand, read the feedback, repeat. The interface stays out of the way so the decision is the focus.

The import workflow has a small prerequisite: you need to be able to generate solution files in whatever solver you use, and to understand what the export format expects. If you are already producing solution files, the transition is straightforward; if you are not, start with the pre-built drills and build up.

Practical examples

Scenario A: Big Blind defence practice You keep folding up too much from the Big Blind against button opens. Pick a pre-built BB defence drill and run it for twenty minutes. Every time the trainer flags a fold that should have been a call, you feel the leak in real time — and the repetition is what converts the correction into instinct.

Scenario B: Importing a solver session You spent an afternoon in a solver mapping out a specific three-bet pot structure. Rather than re-deriving it next week, export the solutions, load them into the trainer, and drill that exact spot in rapid-fire format until the correct frequencies are automatic. The solver gave you the map; the trainer made the map yours.

Performance and system requirements

Simple GTO Trainer is a trainer, not a solver: it scores your decisions against existing solution data rather than performing heavy iterative calculations, so it is a relatively lightweight Windows desktop program. The developer has not published a formal specification; it should run comfortably on a standard modern Windows PC.

Pricing and value

The licence is sold per period rather than as a lifetime purchase. The official site’s pricing is behind an interactive purchase flow that could not be captured for this review; a 2026 third-party review lists the Pro licence at $199 for twelve months. Confirm the current price on the official site before purchasing.

A free trial is offered, which is the right way to evaluate the drill workflow before committing.

On value: if you already own a solver, the trainer converts that solver’s output into durable skill, which is where most study money is actually wasted (solutions that were never drilled). If you do not own a solver, the pre-built drills still provide real value, but you will eventually want the full ecosystem — in which case weigh it against all-in-one platforms such as GTO Wizard.

Advantages and disadvantages

Advantages

  • Import your own GTO solution files — flexible pairing with any solver you use.
  • Pre-built drills mean no solver is required to start.
  • Instant, specific feedback on your decisions.
  • Part of a mature product family (SimplePoker).
  • Free trial before purchase.

Disadvantages

  • Period licence, not a one-time lifetime price (third-party listing: $199/12 months — confirm).
  • Windows only; no current mobile experience.
  • It trains, it does not solve — you need solution sources.
  • Pricing is not clearly published on the main product page.

Comparison with alternatives

All-in-one platforms GTO Wizard is the broadest option: its own solver, a huge pre-solved library, a trainer and hand-history analysis in one subscription ($49–$279 per month by tier). Simple GTO Trainer is narrower, cheaper to run and — through its import function — solver-agnostic.

AI coaching PokerSnowie coaches you with its own AI ($29.90/month or $199.90/year, Windows plus an iPhone preflop tool). The approach differs: Snowie plays at you; Simple GTO Trainer scores you against defined GTO solutions.

The solvers it pairs with It makes sense alongside Simple Postflop (same developer, $299 local solver), GTO+ ($75) or PioSolver (€450/€800) — the import workflow is what turns any of them into a complete solve-and-practice loop.

Poker room rules and restrictions

GTO training is off-table study. Using any software to inform your decisions while a game is in progress is Real-Time Assistance (RTA), prohibited at essentially every major room, with bans and fund forfeiture as the standard outcome.

Drill at your desk; play at the table. And check your specific room’s software policy for its current position.

Final verdict

Simple GTO Trainer is a specialist tool for a specific stage of study: you have the answers (from drills, or from your own solver work), and you need them to survive contact with a live opponent.

Choose it if: you want flexible, file-based GTO drilling on Windows, particularly if you already run a solver and want to practice its exact output.

Skip it if: you want an all-in-one platform with its own solver and library (GTO Wizard), you are on Mac/Linux, or you are still building the theoretical foundations that make GTO feedback meaningful.

FAQs

Does it calculate GTO solutions itself? No. It trains against existing solutions — its pre-built drills or files you import from a solver.

Can I use it on a Mac or Linux? No. It is a Windows desktop program, and the family’s older mobile apps have not been meaningfully updated.

Is there a free option? A free trial is available; the full licence is period-based (a 2026 third-party listing shows $199 for twelve months Pro — confirm current pricing officially).

Do I need to own a solver? Not to start — the pre-built drills work on their own. To unlock the main feature (drilling your own solutions), yes: you need solution files from a solver.

Is this the same as the old GTO Trainer? No. The former gto-trainer.com product is not to be confused with Simple GTO Trainer, which is a current SimplePoker product.

Is it allowed at the table? No — like any study software, it is for off-table use only. RTA during live play is banned at major rooms.
