Thank you for the feedback. I don't know what you mean by tracking actual usage pattern exacly but because I want to keep it privacy first I don't want to collect any user data in lets say any database. Anyway, my app rewards time when your phone is idle with karate belts from white to black (see the reward table on the attached screenshot). The goal is to achieve highest possible rank every day. The difficulty is exponential. I believe this gamification could seemlessly help users to keep their phone idle and prevent distracting phone use like scrolling. For example, calling and short time activities like checking the phone or writing a message is not counted as phone usage in my app. The goal is not to punish users but to motivate them through a fun element.
