Okay, the exercises are okay but there are a few things that should be addressed. The app offers sleep breathing. That is great. But the fact that one cannot use it in flight mode defends the purpose of sleep breathing. I always switch off any reception near my bed and this app doesn‘t work without wifi or data. Also if you switch your phone to silence the audio doesn‘t play. Another thing I do before bed. I don‘t understand whether the different programs should be listened to in order since the color of the buttons doesn‘t change once I listened to a chapter. Finally I find the accent of the voice a bit disturbing and think a professional voice artist and native speaker would be a better choice. So I tried the app but definitely won‘t pay 5$ per week.
