The biggest problem for me is that 90% of the nights it shows my awake time as 0, which is impossible. I am using verity sense and I dont know how it gets it so wrong. Also, I dont like big blurred cards reminding that you have to buy a subscription, you can make it more subtle. The first main screen seems use less, and the app does not allow to change the start screen. So for me it makes no sense for me to buy a subscription or even continue using the app which gets the main info(sleep) wrong.

Hi Roman, danke für dein Feedback. Beachte bitte dass die Wachzeit die du siehst nur Phasen länger als 2 Minuten beinhalten, denn das sind die Wachphasen die die meisten Menschen auch bewusst wahrnehmen. In deiner Gesamtschlafzeit ziehen wir aber natürlich alle kurzen Wachepochen ab. Falls dir das nicht hilft schreib uns gerne auf hello@sleep2.com
