What it is
Poker combinatorics training app called On The Flop it's a quiz app for players who have some familiarity with the concepts but want to sharpen their analytical skills on the go. It shows you a real flop and a preflop range you guess the counts for things like pairs/sets/flushdraws/OESDs, then you get a breakdown and accuracy to see where you’re off.

State of development
The app is currently in closed testing right now. If anyone wants to try it, please let me know. Any feedback on the app is appreciated although feedback isn't necessary. The app is primarily designed for phone and not optimized for tablet atm. If you’re up for it, a Google account is required so please DM your email so I can add you to the tester list.

Quick look
Here’s what the app looks like in practice. It’s meant for short, focused reps so you can work on board-texture recognition and a home page that lets you jump in quickly as well as displays your progress over time. There is also a short guide on poker combinatorics if you're new or want a refresher.


This is how a quiz typically goes. You can enter the exact combos for a given hand or simply enter the percentage that hand type occupies of the range. This quiz shows a simple flop and a range, but you can set 2 dead cards to act as blockers as your holecards typically do. The next screen shows the results with a break down comparing your entries vs how the board actually connects to the flop.
