Ultimate Par Timer

Simple par timer for sports practice (such as dryfire).

Vision

Develop a par timer that will be easy to setup in short period of time. The current timers (software and hardware) take some time to start up, re-configure and change a par time.

Goals

1. Start up time about 3 seconds
2. Adjust time at most 15 seconds
3. Hands-free repeats

Demo

Let's try to set 3.5 seconds interval with 5.0 seconds repeat:
