FitBrain app for iPhone and iPad

FitBrain is a game that tests your memory.
The game displays randomly selected emojis from the devices emoji collection. The objective of the game is to touch on an emoji only once. As you touch on an emoji the same set of emoji is shuffled and displayed again. If you touch a previously touched emoji then the game ends.
The game has three levels: Easy, Medium and Hard.
Easy: 9 emojis are randomly selected from the collection and displayed in a 3x3 grid.
Medium: 16 emojis are randomly selected from the collection and displayed in a 4x4 grid.
Hard: 25 emojis are randomly selected from the collection and displayed in a 5x5 grid.

You must complete each level within the time allowed for that level. For Easy it is 30 secs, medium 90 secs and for Hard it is 180 secs.

Your score is calculated by summing up the remaining time in each level. The lower this number the higher the rank.
