Overall, this is the HIIT app I recommend.
I have tried several HIIT apps and this is the one that fit my needs best. This developer has a different app that looks better (Tabata stopwatch) but the functionality is more limited. However, they tell me this app will get a similar makeover in the near future. When the “remodel” comes out, for my needs and likes, I bet this becomes a 5 star app.
As it is, it’s still the best HIIT app I’ve tested and used. I have one small gripe. You can’t skip ahead intervals. If I feel like starting the next interval early, I have to wait for the rest period to end. Otherwise, I have to stop the program, edit it, and then start over.
