I've recently developed a simple rest timer app for iOS and I would love to get your feedback on it. I made it because I needed something easy to use to track my rest periods.
You can change the timer duration while the timer is already running without resetting it.
It works in the background, warns you with a sound notification to prepare for the next set before the timer ends. It plays nicely with your workout music.
You can restart the timer for the next set without unlocking the phone.
Check it out at http://waitwaitgo.com/ It's free. Let me know what you think. I'm looking forward to your feedback.
