The poker math app that drills the counting until it is automatic

Free, and free all the way down

There is nothing to buy. No subscription, no trial, no energy that runs out, no lesson behind a wall. There is no account to make, and the app makes no network calls, so it works on a plane. The App Store privacy label says Data Not Collected, and it means it.

What you drill

• Outs. Count them, find the draw, spot combo draws, and discount the ones that lose.
• Pot odds. Read the price, call or fold, and how often a bluff has to work.
• Equity. Against one hand, against a range, and how wide your honest guess should be.
• Reading the board. The nuts, what the board makes possible, and blockers.

Nearly forty short levels, from naming a flush to bluff-catching. Each one takes minutes.

Every answer explains itself

Getting it wrong tells you nothing. Every question ends with the reasoning: which card you missed, why the price was wrong, what the board made possible. Skills you have shaken come back on a schedule, so what you learned in March is still there in June.

It grades how sure you are

Most trainers only take your best guess. Off the Felt also asks how sure you are. A band wide enough to always hold the answer scores worse than a tight one you hit. Knowing what you do not know is a skill too.

What it is not

It is not a solver, and it will not hand you a preflop chart. It is arithmetic and counting. Nothing in it claims to be GTO, and nothing in it promises you will win more. It is play money and practice. If a question is wrong, I want to know, and I will fix it and say so.

Why I made it

I kept getting the counting wrong in the moment and right in the car afterwards. Under time pressure the arithmetic does not fail gracefully. It just does not arrive. So I built the drill I wanted, and I still use it.
