Interval Timers from the App Store support only 1-second step sizes. Let's say you plan to run 6-min miles on the track, and you want a timer that gives you a sound signal every 100m to ensure you are right on pace. You can set your regular timer to either 22-sec and run a 5:54min/mile pace, or to 23-sec and run a 6:10min/mile pace. It is however not possible to get it right to a 6:00min/mile pace. For this reason we developed our own timer that allows you to run an any target pace. Enjoy!
