RNGTool is the easiest way to generate a random number, flip coins, roll some dice, draw some cards, and select random letters, right from your iPhone (or iPad)! Your numbers are saved while the app runs, so you can access all of your history.


RNGTool offers the following modes:

Numbers:
Generate a single random number using only a minimum and maximum number. The simplest way to generate numbers.

Coins:
Flip some coins! Displays the total coins flipped and how many were heads or tails. Supports flipping up to 50 consecutive coins.

Dice:
Generate numbers using your standard 6-sided dice. Supports rolling up to 9 dice at once.

Cards:
Generate numbers by drawing a hand of cards. Optionally, you can display the point values of each card drawn, with the Ace being toggleable between 1 and 11 points. Supports drawing up to 7 cards at once.

Marbles:
Generate letters by rolling some marbles. Supports rolling up to 9 marbles at once.


To get started, simply choose a mode from the main menu, and press the play button! For the dice and marbles, you can also shake your device to roll.

RNGTool also offers a companion Apple Watch app, allowing easy access to random numbers right from your wrist. Modes on Apple Watch support fewer simultaneous numbers, but all modes are still available.
