Just pick your interval durations and click GO!

"Plays well with others," so if you have favorite apps for audio or fitness tracking it will work well alongside those. Audio voice alerts or tones will momentarily lower the volume of your music or briefly pause spoken audio just long enough to hear the alert, then let you get right back to listening!

This app does not track or collect any user data.

What’s New

Version 1.4

Now with a companion Watch App! Change intervals and alerts, start and stop your session without getting out your phone!

Added a dark mode option to the iPhone app!

This app is still free, all features available without ads or restrictions. But if you would like to support further development, there is now a tip jar!

This update also includes performance improvements and bug fixes, and removes the Pause button.

This app is great!!

I use this app three or four times per week for my run intervals. I like the simplicity of just having to dial the run and walk times. Had an issue at first with not signaling the intervals after the phone locked but the developer fixed that. Can’t say enough good things about this app. It works with Runkeeper and Pandora running in the background also.

Simple app, that works great

My wife and I are doing run-walk-run training for a marathon Anand we needed something on our phones to queue us to start and stop. The trick was to find something that would work with Runkeeper and Apple Music.

This little app works great. I’ve been on 20+ runs now with all three going and works perfectly-never fails to tell you to run or walk.

Great, simple app

All I needed was an interval timer and I didn’t want to fork out a fortune for a Garmin. This app is perfect - simple concept and does just what I need it to do.
