Everything your dice need

Run statistical tests (chi-squared, Bayesian analysis) on your physical dice to find out if they're truly balanced.

Record every roll during your game sessions and get real-time statistics on your dice performance.

Roll realistic 3D dice with physics simulation — perfect when you forgot your dice at home.

Organize all your dice and sets in one place. Name them, color them, love them.

All your data stays on your device. No server, no account, no tracking. Your dice, your data.

How it works

Add each die with a name, type and color.

One tap per roll. The numpad is designed for speed.

Chi-squared, Bayesian analysis, interactive charts.

The universal TTRPG question

"Does my D20 hate me, or is it just bad luck?"

Now you can answer it with science. No more blaming luck.
