Dice settings, My Presets and Roll History are kept in the app's own storage. Deleting the app deletes them as well. iCloud sync is not supported.

Reset App at the bottom of App Settings erases all settings, presets and roll history, and it cannot be undone. A Pro purchase is not affected.

Tap the faces chip at the top of the screen to open Dice Settings. Tap the pencil box and enter any number from 2 to 100 under Custom Faces to roll a die with that many sides. Dice beyond 10 faces need Pro.

The 3D view supports 2 to 20 sides. Larger dice are shown in 2D.

The app starts in your device language. To change it, open Language in App Settings and pick one of 13 languages. The switch happens inside the app right away.

Dice beyond 10 faces, more than 10 dice at once, the Neon, Thunder, Gold, Flame, Wood and Marble skins, and custom icons need Pro. So do verdicts after you change a Quick Preset's rules. The d20 Check preset rolls without Pro.

Rolling, history, presets and Roll together work without an internet connection. Only buying and restoring Pro need a connection to the App Store.

Roll together uses the Local Network permission to find nearby devices. If you did not allow it when asked, turn on Local Network for Dice Master in the Settings app.

Turn off Shake to Roll under Controls in App Settings, and shaking the device will no longer roll the dice.
