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. ### 4/5 — Great app! *2024-06-13* 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! ### 2/5 — Cannot pause it *2024-03-17, version 2.2.4* 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. ### 5/5 — Great app to Gradually get back into running *2023-10-22, version 2.2.4* I love the app . I just wish the prompts could still be heard when it’s minimized. ### 3/5 — Walk to run *2023-08-10, version 2.2.3* You can set yourself up to run an interval, then walk an interval. But you can’t start off with walking. Please make this an option!!! ### 1/5 — Stoped working with music in background *2023-07-04, version 2.2.3* It was fine until I started listening to music and put my phone in the pocket. Then the timer just froze ovwr and over again. ### 2/5 — Sound *2023-01-14* Will gladly change rating if problem can be fixed: Can’t get sound to notify when phone is closed, I have music playing, but other apps have reduced the volume to give interval alert. I’ve checked my settings, and another similar app works just fine, but this one won’t and I’d prefer to use this one if I can get it working. ### 1/5 — Poor notifications … disappointed *2022-10-16, version 2.2.3* The app is either not capable or not easy enough to figure out how to get audible notifications for each interval. I was only able to get a vibration which doesn’t really work while rubbing with my phone in my running sports pouch pocket. ### 5/5 — Exactly what I needed *2022-09-29* Perfect for what I needed. Most reviews are old and they have fixed what folks were complaining about. I did have to purchase the $1.99 upgrade to get more than 10 minutes of running time, but that’s common so I didn’t mind spending it. Very straightforward and so simple to use. Super happy with this app no complaints so far!! ## Frequently asked questions about Interval Timer ### What does this interval timer app do?
