Randa lets you easily generate a random number. Just set a minimum and maximum number and you will get a random number in that range. This can be useful for decision-making, picking stuff from a list, board games, dice rolling, coin flips, etc. For example, it's Netflix & chill night and you cannot decide on a movie. Just generate a random number from 1 to 20 and pick the movie at that position in your watchlist. Need to make a yes or no decision (coin flip)? Just set the minimum to 0 and the maximum to 1. You can shake the device to generate a number. And you can press and hold the number to copy it. Note: The app generates truly random or consecutively unique numbers (opt-in). However, it does not ensure all numbers in the range will appear before repeating. This feature, known as exhaustive randomization or shuffled sequence selection, is not supported.
