About
Binary Dice is a dice roller for Apple Watch that you set with binary.
Four digits choose the die. Tap a digit to flip it: 0110 is a d6, 1100 is a d12, and 0000 is a d20. Hold a digit to type any die from d1 to d1000. Prefer plain text? Swipe sideways to switch to 1d20-style dice.
Three buttons do the rest:
• Hexagon: how many dice to roll, 1 to 20.
• Red button: roll. The total lands on the button, with every die listed under the roll.
• + / −: a modifier, added or subtracted.
Use the buttons or the Digital Crown to change values, or hold any button to type a number. Swipe down for advantage or disadvantage.
For the big moments, swipe up or flick your wrist. The roll fills the screen and bounces to your result. Tap to skip ahead, tap again to roll again.
Max rolls glow green and 1s glow yellow, and your watch taps your wrist.
Favorites: save the rolls you use most, name them (Longsword, Fireball), sort them by tag, and mix dice like 1d20 + 2d6 + 8. Roll them one at a time or all at once.
History: every roll, newest first. Star one to save it as a favorite.
Initiative: for the DM. Add players and enemies, roll the whole table, and keep turn order on your wrist. Save your party for next session.
Make it yours in Settings:
• Add the modifier to each die or once to the total.
• Choose what the crown changes, and what 0000 and 1 1 1 roll.
• Daggerheart mode: 0000 rolls Hope and Fear, and advantage adds a d6.
• Pick the roll animation and which rolls glow.
A built-in manual is one hold of the red button away. Your setup is remembered between launches. Works entirely on your watch, no iPhone app needed.
No accounts, no ads, no subscriptions, no data collected.
