Randomity Timer generates random periods of time and counts them down continuously one after another. You can choose minimum and maximum limits in which the time period will be generated.
Very suitable for red-light/green-light (allow/deny) and other such games.
Able to work in background, so you could use it with other apps (gaming, video playback, etc.). Also your device could say a phrase at the beginning of every new time interval, by default it says Green light and Red light.
Play with it and have a fun!
