simple app

too simple that you don’t have options for sound effects, can barely hear the interval announcer

Needs a few more things to be perfect

I love the simplicity of this app and it almost meets the need of what I’ve been looking for. Three things that would make this perfect:
1) a tabulation of total time of the workout you’ve created before getting started
2) announcements at the cool down period and at the congratulations screen, like the warmup and the intervals have (I put my phone in a running belt so if it doesn’t talk to me, I don’t know I’m at this point)
3) the ability to still announce when the screen is turned off. Right now, if I turn off the screen it will notify me visually but not over audio. And because I’m not looking at my phone while running, I have to keep my screen bright.

Response from developer

Thanks for the detailed feedback! Interval Run 3 was recently released with major improvements to workout experience, including much better support for running with the screen off and in the background, along with a redesigned workout experience. Please give the latest version a try. We really appreciate your suggestions, and if you notice anything still missing, feel free to contact us at support@intervalrun.app

Great app!

Would give 5 stars but only 2 options - run or walk. For longer workouts and choosing a run/walk/jog split it would be nice to change intervals based on set vs having just a set run or walk period. Still a great app!

Response from developer

Thanks for the feedback! Interval Run 3 now supports more flexible custom workouts with multiple steps, intervals, and repeats, so you’re no longer limited to a simple Run/Walk pattern. Please give the latest version a try, and if there’s anything else you’d like to see, feel free to contact us at support@intervalrun.app

Cannot pause it

It would be nice if you could have an option to pause the timer. Also, the “Time remaining “ must be larger so I don’t have to put my glasses on to read it !!
Otherwise, a nice simple timer.

Great app to Gradually get back into running

I love the app . I just wish the prompts could still be heard when it’s minimized.
