Performance Timer — App Store rankings

About this app

The developer's US App Store description, in full.

Performance Timer is a large-display countdown timer developed to be used to monitor the time remaining in a performance, presentation, etc. Performance Timer does not sound an alarm when the time runs out. Rather, when the timer reaches zero, the numbers turn red and the timer starts counting up so that you can see how long you've gone over your target time. The time can be set from 1 to 99 minutes.
