Would anyone like to help me test out my timer app? I'm developing it for a friend of a friend. You can choose length of rounds between 1 and 10 minutes, rest time between rounds between 15 and 60 seconds, and number of rounds from 1-5 and infinite. A warning whistle blows as a 30 second warning each round, and bells sound at the beginning and end of each round. Your settings are automatically saved (unless you elect not to, in which case you can save manually). Sound can be turned on and off in the settings menu (next to Start).

Try your best to break it! Let me know if anything works funky!
