Well-done app but most options not free (freemium)
WhitneyNC
This app is easy to use and works well. But most options require $2 upgrade. The free version gets you about 10 minutes of run time (although you can quickly start a new cycle) and limited time ranges for walk/run.
Developer Response
Thanks for the kind words and feedback! Interval Run has changed a lot since this review. The new Interval Run 3 includes a redesigned experience, much more flexible custom workouts, and many new features for run/walk interval training. We'd love for you to give the latest version a try, and feel free to reach out at support@intervalrun.app with any feedback or suggestions.
I want a refund.

Where do I start? I purchased this to do some running intervals with. Runners beware. This is not the app for that. I immediately had to purchase the full version for intervals 2+ minutes in length. I ended up setting a couple of run/walk sets totaling 10 minutes and was doing an out and back style run. The prompts do not sound if your phone is on locked screen. Who runs with their phone in hand and screen on? I put mine in a carrier so I can’t continue to take it out and check the time. I missed the first interval by over 4 minutes because I never got a prompt. Then I realized my phone is on silent. In other running apps, you can silence your phone so that you only hear your music and your run prompts (MapMyRun, Nike Running Club, etc.). This app does not do that. When my sound was on, I STILL didn’t get any prompts and didn’t know when my last interval ended. Again, because you have to have your phone screen on 100% of your workout to see them. Runners, don’t waste your money or time. Go pro on one of the better known apps for run training. I wish I could get my money back.

We're sorry you had such a frustrating experience, and thank you for taking the time to explain what went wrong. Interval Run 3 has since been released with major improvements for runners, including reliable audio prompts while the screen is locked or the app is running in the background. Please give the latest version a try. If you experience any issues with audio prompts, contact us at support@intervalrun.app and we’ll be happy to help.
Needs a few more things to be perfect
Runmama
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.
Developer Response
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
Doesn’t work without app open/screen on
oneberrytwoberry
Not the first 99 cents I’ve wasted and won’t be the last, but the many reviews I didn’t read before buying are correct: the voice controls do not work if the app is not open and active. You cannot, say, set an interval and then put your phone in your pocket while you listen to music or podcasts and have the voice interrupt and tell you when to stop running or walking. This app is basically useless unless you are running on a treadmill with your phone sitting in front of you to see the banner notifications, or with the app open to hear the voice (and you must have a tons of battery life, of course...)
