5 stars: LOVE THIS APP! 3 weeks improved from 1:49 to 3:24 static hold. FEATURE REQUEST: A 'set departure' table. Where you can have a variable hold time opposed to a set time. Your one breath mode gets pretty close to what I'm looking for
5 stars: Excellent app. Can't believe it's free. I just hope they put volume button mapping for the contraction button. Other than thay, everything's perfect. Edited: They really do have those button mapping for the contraction. So silly of me. Awesome App!
4 stars: I don't know how to explain it, but sometimes seconds run too fast. It is like the seconds in this app a bit shorter then real. Maybe I am crazy. I feel it every training. And one more. Every training I add one sec to holding time. Usually I have 8 laps, so I need 8 times to change the time (add 1 sec). It makes me crazy. Is there any way to change all laps at once?
3 stars: so far so good. the only issue I have found is when I set the setting to use the sensor on my phone, it turns on the flashlight which is right above the heart rate sensor on my S7 which ends up burning my finger so I can't use it which is the only reason I don't give it 4-5 star. hope you guys can fix this bug as I really enjoy the app!
