User reviews

Lite version is poison

The description of the light version said that I’m like pro it can’t record workouts. This was fine and I started a workout using my watches usual mechanism then switched to the HIIT app. What I learned afterwards is that it had stopped the original workout. Furthermore, it prevented my watch. From recording the workout at all. Spent an hour manually correcting data in the Health app, but even then wasn’t completely successful. For somebody who’s engaged in an actual training regimen, who is careful about logging activity and tracking their training load. Just trying this app out turns out to be very destructive zero out of 10 will not try again.

What does the paid version do?

What are the limitations to the Lite version that the paid version can do? For me this version does not stop after 4 intervals.

Simple, works great, finally a Norwegian 4 app!

This app is great. It is easy to use , the explanations are very detailed, it works flawlessly. Turn it on and it will give you your max heart rate. It has a timer for when you 4 minutes are done and the beeps plus dial on colors really help a lot when you are exercising hard and you can’t fumble with your watch. If you’re into HIIT, this is the one for you. I’ve been doing HIIT for years and I finally found an app. that’s easy and efficient. Even took the time to review it and I rarely review apps, shows you how much I like it.
