Simple and easy but...

Great app, simple and easy to set up and use but the prompts need to be louder or different options. The voice is very muted and monotone, I had to really listen for it while I was also listening to a podcast and missed it once. I’m not sure I could hear it if listening to music. Love the functionality though!

Hi Krfrey! In new update we've updated notifications voice, hope you won't miss it now :)

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.

Hi j.and.t! Voice prompts while app is in background is in our roadmap for next update. Hope we'll be able to implement them and app will be useful for you too.
Thanks for such detailed feedback and have a good day!

Exactly what I wanted!!!!

I’ve been trying Couch to 5k type apps for a while and for one reason or another there were things I did t like about it. Either you couldn’t customize it exactly how you wanted it, or there would be an issue with it working with Apple Music, and on and on. Then I found Interval Run. You can customize it how you want. Also, it works perfect with Apple Music by that I mean you launch Apple Music and it plays, you launch Interval Run and it still plays. And most important, for me anyway, when the voices come in to tell you to run, walk, etc, the music fades down, you can actually hear the Interval app voices, then the music cranks back up. Absolutely no issues. Love it. So now I can set my Apple Watch running workout, start my Apple Music playlist, then start Interval Run and I’m off.
