Great for classroom motivation

Mumball gets a little boring sometimes, not with GameTimer. If the game show buzzer goes off randomly while you’re holding the ball -you’re out! Not enough time to play one more round? Well then, if the Gong sounds while you’re holding the ball - you win! Not playing games? Ok. If you are working when the timer sounds you get a treat from the teacher’s desk, or you get to take a break. This tool is totally worth the $0.99. Thanks for making it. I wonder what else I can do with it. I’d give it a five star rating if it had more sounds, or I could add tone from iTunes.

It does what it says, it’s a random timer! I needed this for an activity with students, and I definitely wasn’t disappointed. I am timing between 15 and 50 seconds and anywhere in between this time duration the alarm will go off, and I announce special modifiers to my activity! It’s a lot of fun.

Works as advertised!

If you don’t have someone handy to yell “switch!” at random intervals and would like an app to serve that function, this is exactly what you want! I use it in my guitar practice.

The UI is simple and effective; the feature set is appropriate to the task.
