Quality time is an app that monitors your day's smartphone usage, a week's usage, a month's usage, and also tells you no of screen unlocks you happen to make in a day. The no of screen unlocks in a day and a day's usage is visible via your notification bar, for all other analysis you have to open the app. It is basically a new entry in the play store and is bound to improve over time.
Review:
I happened to be using this app for the last few weeks. It seems to do the job just fine without drinking much of battery juice. How I'm rated according to this app on smartphone usage, is 20hrs a week on an average.
