Terrible
The information it presents is next to useless. I thought I'd be able to see how many hours I'd spent on each activity, I should have looked much closer at the graphs. The information they present is unclear and vague. The app doesn't scale properly to the plus size phone. You can't specify the start day of the week, and the app doesn't honour your calendar settings. You have to manually step through every week of the year to get to the current week. Just unusable.
