Poker Assistant

Otter Crew's Poker Assistant

GTO study that stays on your machine.

Study solved ranges, drill the spots you keep getting wrong, and run your own hand histories through a solver without uploading them anywhere. The app is free, and the complete heads-up solution set comes with it. Bigger tables come as packs you buy once.

Coming to iPadOS, macOS and Android.

What you can do

  1. Find the hand that cost you the most

    Import a session from PokerStars, GGPoker, 888poker, Winamax or iPoker. Poker Assistant detects the site, runs every hand through the solver, and lists them by how much each decision gave up. Open the top one and see the mix you should have played.

  2. See what every hand wants to do

    Pick a spot and the grid shows all 169 hands with their action mix. Switch to EV to see what each action is worth, or to equity to see how the hand does against the range you face. A 70/30 mix is the solver telling you both plays are close, and you can read exactly how close.

  3. Drill the spots you get wrong

    The trainer deals you a spot from a solved solution, grades your action against the mix, and shows the EV you gave up. Misses go into a drill list, so the next session starts with the hands that need work.

  4. Exploit a player who over-folds

    Lock a villain's real tendency into a spot, folding to a c-bet seventy percent of the time instead of forty-five, and re-solve. The counter-strategy shows which hands start betting and how much the adjustment is worth. It also shows what the same adjustment costs when the read is wrong.

  5. Heads-up is free. Bigger tables are a pack.

    The free app includes every heads-up preflop solution, 8bb to 200bb, with ante, rake and straddle structures. Packs cover 3-handed through 9-handed, each solved for a stated structure such as 5% rake capped at 3bb or a 2bb straddle. You buy a pack once and it stays yours.

  6. Your hands never leave your device.

    Hand histories, practice results and every spot you look up are stored on your tablet or Mac and nowhere else. There is no account and no server. Nobody, including us, can see which spots you studied.

  7. Watch the solve settle

    Every preflop solution is measured after solving: how much a perfect opponent could still win against it. The shipped packs come in under one big blind per hundred hands. The solver is built on published methods, and the accuracy page names them and says what the number means.

Questions players ask

Do my hands ever leave my device?

No. Hand histories, practice results and every spot you look up are stored on your tablet or Mac and nowhere else. There is no account and no server behind the app. Nobody, including us, can see which spots you studied.

What is free, exactly?

The app, and every heads-up solution in it: 2-handed, 8bb to 200bb, with ante, rake and straddle structures. The trainer, hand-history import, node locking and the preflop builder all work on the free set. There is no daily cap on spots, hands or drills.

Will heads-up stay free?

Yes. It is a permanent part of the app with no end date. If that ever changed, you would keep what you have installed.

Can I use it while I play?

No. Poker Assistant is a study tool for work away from the table. Every major site bans real-time assistance, and most name solvers and charts explicitly. Using this app while a hand is live breaks their rules and can cost you your account. Close it before you sit down.
