Build complex rolls, get detailed results, and keep up with your recent roll history. d20 is intuitive, elegant, and powerful.
Update Jan 1, 2018: Version 2 of the app is out! See https://d20app.me/ for more. Version 1 is no longer available from the Mac App Store. This page will remain up for now and the free web version of the v1 app will remain available.
To use d20, simply click on the die you want to roll and click "Roll." If you want to roll multiple dice, just click all the dice you want to roll, then click "Roll." You can even add modifiers to your roll. d20 lets you build complex dice combinations with just a few clicks.
The results pane keeps track of all of your roll results. It prominently shows the total of all the dice, plus (or minus) any modifiers. It also shows the result of each individual die, highlighting critical hits and misses. Results will be cleared when you close the app.
d20’s smart layout feature lets you resize the window to fit your workflow and style of play.
Mouse-averse? d20’s keyboard shortcuts let you roll even faster.
Set d20’s “Always on top” option to keep it floating over all other windows.

This project began life as a web app. As a thanks to all the great free tools, code, and help I’ve received through the years, I’m keeping the web version available, free, forever (well, as long as I can afford to keep the servers running!). Give the web version a try and, if you love it, consider supporting development by getting the app.
