There's this feature to limit you from using the app when you've spent a certain amount of time on it. When I enabled it, I found out that I reached the limit way before sunset!
I don't know why we're addicted to this tech devices but it's really messing up the way we should balance our time, it's taking too much of our time and I think this should be a concern for anyone who wants to live a better, fulfilled and healthier life.
My girlfriend used to have this feature turned on. Every time it would alert her that she was over her limit, she would just ignore it. So it didn't work too well on her. Maybe if there was a password that she didn't know and it locked her out until the next day it would be different. That is a bit much though.
