Tracking time spent in iOS applications I know RescueTime exists for Android but I do not see anything like it for iOS. I'm guessing such an app may not be possible on iOS because of the permissions and how apps have been sandboxed from one another. However, I'm hoping that I'm wrong. 

Has anyone found an app which at the end of the day a user could look and see a list which shows the total active time spent in different applications for that day?

I'm looking for something like the following:

Summary for YYYY-MM-DD
Total Time: 2h28m

 - Safari: 48m 
 - Tweetbot: 32m 
 - Mail: 23m 
 - Cooks Illustrated: 22m 
 - Yelp: 12m
 - Messages: 8m 
 - OmniFocus: 3m
The beta of iOS 12 includes Screen Time which solves this problem rather conclusively at the OS level. Here's a couple of my screenshots from revent use:
