Enhancement: screen time stats

[songsammy]

Did some research and found this: android.permission.PACKAGE_USAGE_STATS I am wondering how much help did this app give me on detoxification, so I would like to see a report . Here's what i am thinking about. During a specific time span like Today/week/month/year

• how long is the screen time (total)
• how many percent decrease/increase
• how long have I been using a specific app, order by usage, desc
• how many times have I opened the app, order by times
• which time in day do i use phone most

And it's better if you put it in a widget.
