Preflop trainer for tournaments
Drill your preflop ranges until they stick.
Get a hand and a seat, pick an action, and see the range chart right away. Hands you miss come back in a later set, so practice turns into memory.
Coming soon on the App StoreFor iPhone. Free to try, 20 hands a day.
How a set works
- 01
Read the spot
Your stack, your seat, and what the players before you did. Ten hands per set.
- 02
Pick an action
Fold, call, raise or all-in. Once you answer, every button shows how often the chart plays it.
- 03
Check the chart
Your hand is outlined on the 13×13 grid. A miss opens the explanation, and that hand comes back in a later set.
What's in the app
12 to 100 BB
Ten stack depths, each with four spots: opening, facing an open, facing a 3-bet and facing a 4-bet.
Mixed answers count
The most played action is marked best. Any other action the chart plays at least 10% of the time counts as correct too.
Study exactly what you want
Mix stacks, spots, seats and hands. Want only A2s to A5s from the button? Make that your set.
Live table
Your seat moves one place each hand and each hand plays through to the 4-bet. Keep going until your first miss.
Your own chart
Play a hand differently at your table? Change it in your chart and get graded on your version. The solver numbers stay visible.
Poker math
Count outs, work out pot odds, and spot the flush and straight draws on the board.
Where the charts come from
Every chart was solved with HoldemResources Calculator for an 8-max tournament table with equal stacks, a 1 BB big blind ante and chip EV, so payout jumps are not modelled. Different conditions can change some answers. Treat the charts as a baseline, not the only way to play.

Questions
Is this gambling?
No. There is no real money, no chips to buy and nothing to win. It is a study tool for preflop decisions.
Does it cover cash games?
Not right now. The charts are for tournaments: 8-max, equal stacks, with a big blind ante.
What do I need?
An iPhone with iOS 16.4 or later.
Can I move my records to a new phone?
Yes. Settings > Back up records makes a copy you can save or send to yourself. Paste it into the same screen on the new phone.
How do I cancel Pro?
On your iPhone, open Settings, tap your name, then Subscriptions. Cancel at least 24 hours before the renewal date to avoid the next charge.
I play a hand differently. Is the app wrong?
Charts depend on their conditions and your table may differ. From any explanation you can switch that hand to your own play, and the app grades you on it from then on. If something looks broken, email us.
Start with ten hands.
Your first set takes a couple of minutes and shows you where your ranges are shaky.
