• Create multiple (unlimited) stopwatches and timers.
• All timers/stopwatches can run simultaneously.
• Set a title for each stopwatch and timer.
• Smooth finger-swipe between multiple timers and stopwatches.
• Stopwatch and timer duration can be from seconds to hundreds of days.
• Define multiple intervals per timer and set unique time for each interval. All intervals run successively in order as they expire.
• Customize beep/ringtone, number of beeps, and vibration settings per each timer interval.
• Create repeating timers (if multiple intervals, timer will repeat once all intervals are over in order).
• Add or subtract time from timer even when it is running.
• Robust and persistent. Even when app is closed, device is turned off, or device is rebooted - timers and stopwatches will resume, and timers will alert correctly.
• Use volume up/down buttons to start/stop and reset timers/stopwatches
• Haptic feedback
• Very easy on battery life, and requires very little memory.

• StopTimer makes for great use for multiple purposes:
• Timing yourself while driving long distance.
• Exercising - for exercise and interval training including HIIT (high intensity interval training).
• Cooking or use in kitchen.
• Laundry - setting a timer to alert when it's done.
• Alarm clock - makes for a very effective alarm clock!
• Many more!
