## What is PreFlop GTO Poker Trainer?

PreFlop GTO Poker Trainer is a free, offline Texas Hold'em preflop trainer: 13x13 GTO range charts for open / defend / 3-bet / 4-bet / squeeze spots, our own computed push/fold Nash for 8-25bb stacks, a personal leak analyzer, and a 20-day training plan.

WHY IT'S DIFFERENT
- Honest by design. We never fake EV numbers or mixed frequencies. Hand-tuned ranges are clearly labelled "reference ranges"; only the spots we can actually solve (push/fold all-in equity) show real Nash numbers.
- Works offline. The whole trainer runs on your device - drill on a plane, on the subway, anywhere.
- Free core, forever. The trainer, range charts and mistake review stay free. Pro unlocks the power tools, never the basics.

WHAT YOU GET (FREE)
- Pre-flop trainer: open / defend / vs 3-bet / vs 4-bet / squeeze / cold-call / push-fold, cash & MTT.
- 13x13 range charts you can study hand by hand.
- Smart deal: balanced question bank that mixes raise / call / fold / all-in and only borderline folds - no obvious trash.
- Mistake review pile with light spaced repetition, so your leaks stay drillable.
- Pre-flop diagnosis: an 18- or 45-hand test on the real table, with an answer + explanation after every hand, then a personalised report.

PRO
- Personal profile & leak analyzer - your tendencies (too loose / too tight / passive / aggressive), most-missed spots, one tap to drill.
- 20-day personalised training plan with daily, do-able cards and a streak.
- Our own computed push/fold Nash (9-max 8-20bb, 6-max 10-20bb, BB call-off, heads-up 5-25bb) - measured exploitability shown, not assumed.
- Range-vs-range equity calculator, with optional flop/turn/river boards.

Built by a squirrel who hates fake GTO. Honesty over flash.

Note: an educational study & training tool for poker theory. No wagering, no payouts, no real-money play of any kind.

## Version history (last 2 releases)

### 1.0.1 — 2026-07-15

- Bug fix: on first launch the welcome overlay covered the language button, so new users couldn't switch language at all. You can now change language at any time.
- The welcome cards themselves now translate right away when you switch language.
- Corrected the interface languages this app declares to the App Store: English, Simplified Chinese, Japanese, German and Spanish are all listed now.
- Push/fold charts: fixed the 20bb cutoff range, which was jamming too many hands.

### 1.0 — 2026-07-12

No release notes.
