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 / 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.
- A built-in course in five chapters - foundations, the main line (3-bets, 4-bets, squeezes), short stacks and push/fold Nash, ICM, and a leak-fixing chapter that works backwards from your own mistakes. Every hand and every number inside a lesson is read from the same range data the trainer deals from, at render time, so a lesson can never contradict the drill. The foundations and main-line chapters are free in full, and the short-stack and ICM chapters each open with a free lesson too. The remaining advanced lessons are Pro, and every Pro lesson opens its first page for free.
- Answer a hand wrong and one tap takes you from the feedback panel to the lesson that explains that exact spot - and from the end of a lesson back to your own mistake pile.
- Daily challenge: the same 20 hands for everybody that day, with a streak you can keep.
- Optional timed mode when you want the pressure, off by default when you want to think.

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.
- Custom-table ICM calculator: type in your own stacks and payout structure and it solves that bubble spot on your device, then reports the measured exploitability of its own answer instead of asking you to trust it.
- SNG bubble ICM push/fold across six table shapes, including satellites and 6-handed final tables.
- Import your own solver output as CSV to override any spot's grading and chart. It stays on your device and is tagged "Imported" - we never pass it off as our own solve.

LANGUAGES
