Clatter: Dice Roller

Clatter is a dice roller from Moonlet Labs for board games, game nights and tabletop RPGs. Tap the tray and two six-sided dice roll at once, with the total in large numbers. There is no ad between rolls.

Roll one d6, or a handful
Clatter opens on a plain tray of six-sided dice. Add as many as you need, up to 100 in one roll, and give each group one of nine colours. Read the results in roll order, sorted, or as a count of each face. Tap a die to lock it, then reroll the rest. Big roll fills the screen so the whole table can see, and a tap anywhere rolls again.

Custom dice
Label each side with your own words or emoji, 2 to 20 faces on a die, or paste a list. Make a die for what to cook, who washes up, or a food challenge with friends. Custom faces show as labels and never add to the total.

RPG dice and notation
Add d4, d6, d8, d10, d12, d20, d100, Fudge dice (dF) or any die from 2 to 1,000 sides with a tap. Or type dice notation such as 2d6 + 1d8 + 3, 4d6dl1 (drop the lowest) or 2d20kh1 (keep the highest). A single d20 gets a switch for advantage and disadvantage, and dropped dice stay on screen, struck through.

Saved rolls
Name the rolls you make every session, put them in order, and roll one with a single tap. Starter rolls include two dice, d20 with advantage, 4d6 drop lowest, percentile and Fudge dice.

History
History keeps your last 200 rolls, each face in its dice colour. Open one to share it as plain text or roll it again.

Score keeper
Scores is the second tool: a score sheet for card games, board games and game nights. Choose Rounds, highest total wins; Rounds, lowest total wins; First to a target; or Counters for running points or life totals. Add up to 12 players, tap any cell to enter a score on a keypad that adds and subtracts (45−10), and undo or redo any change. Clatter can also pick who goes first. A game never ends by itself; when you end it, see the final standings, ties included, and share them or play again.

Fair rolls
Every face is equally likely. Each roll is picked before the dice move, so short runs of the same number are normal. Every face is drawn with Android's SecureRandom before any animation starts, and the tumble only shows a result that already exists. There is no hidden mode.

Privacy and ads
No account and no permissions to grant, and every feature works offline. Your rolls, dice, players and scores stay on your phone and in your own Android backup; a roll or standings you share go only to whoever you send them to. The app is ad-supported. A banner sits at the bottom of the main screens, with a clear gap above it so a tap meant for the dice never lands on an ad. There is no ad between rolls or on Big roll, and the only full-screen ad can appear after you end a game, at most once per game. Ads are served by Google AdMob, which may use the advertising ID. Moonlet Labs collects crash reports and usage analytics through Google Firebase, linked to pseudonymous app identifiers rather than your name or email; they never include your rolls, labels, player names or scores. Where the law requires it, the app asks for your consent first, and privacy choices are in Settings. Privacy policy: moonletlabs.com/privacy.html
