It shows a chart of total usage over time, and by app total percentage, but doesn't show usage over time by app. It also doesn't show me how today's numbers are different from yesterday's numbers, which is what I really need.

Only thing I notice is that "Google services" is higher in the listings than I've noticed before, but the total usage doesn't seem enough to account for the difference. Screen is still 70%, but I haven't been using it more than usual.
