Now I’m in week 10 of a second 10 week program, and this little watch app has been so useful! The only downside: you can have only 20 reps, and the book, on the Tabatas days, calls for three groups of eight: oops, that’s 24! Hey, that’s OK, Tabatas are hard anyway :-) 20 is fine. I really like how the results of the workout feed into the activities app. In order for this to happen, you have to agree for access to Apple health. Make sure you decide to do this the first time, otherwise you will have to delete the app and reinstall it again to activate this. There are several different configurations of HIIT that I do, and it is very easy to adjust those using the watch interface. It comes with a Phone app as part of it, but I have never used it. I always use the watch. I would definitely recommend this app if you are doing high intensity interval training. Update at time of WatchOS 26: App still counts great, but does not appear to display heart rate anymore. I am hoping for an update soon ### 4/5 — It's perfect for my needs. *2024-09-08* I love your app for its simplicity and functionality. I have two quick questions: 1. Are there any planned updates for the app? 2. On my Apple Watch 5, the Haptic 1 sound doesn't work. Do you know anything about this issue? Thank you for your help. ### 4/5 — Needed *2024-06-09* A volume control and the ability to change the sounds (only a whistle now). Otherwise, good. ### 5/5 — Hat nur Funktionen die gebraucht werden *2024-05-24* Und mehr muss nicht sein. Kleine, feine App. ### 4/5 — Haptic Feedback Too Weak *2022-11-24* Love the app, but had to take a point for the haptic feedback, it’s just too light. When doing Tabata I miss the cue frequently. Please make it stronger. ### 4/5 — I use this watch HIIT app several times a week *2020-06-30* I got this some months ago when I was about halfway through a 10 week program in the book “you are your own gym“.

Payed for the app and didn’t get what I payed for. Don’t waste your money. Terrible. **Developer response:** We have added support for Apple Watch Series 4 complications in v2.3. Kindly update the app. If you face any issues, do let us know. ### 3/5 — Limitado *2018-03-07* Seria melhor se os segundos não fossem limitados de 5 em 5 para configurar e se o máximo de repetições pudesse ser considerado infinito ou bem mais que 20 no máximo. ### 5/5 — Thank you *2017-06-06* ... for the last update! 👍 **Developer response:** You are welcome :) If you have any feedback, do let us know. We are committed to make it the best interval training app for Apple Watch. Thanks. ### 5/5 — Awesome and Easy *2017-06-06* Really like this app. Really easy to use and setup. The fact that it's native for the Apple Watch really makes the display and prompts easy and visually appealing. Integrates with Apple Health perfectly.
