I'm in my third month using the app and it is great. Suggestion for improvement:
It would be great if I could see a calendar/daily view to look for gaps in time where no time was filled. Even better if that view could be shown instead of the regular entry screen and I on an adjust easily from that calendar view. I bill to lots of clients in a day and I can't be on top of the timer 100% of the time and this view would help ensure I'm billing everything that should be billed. When I get to the end of the day I can't easily tell if I missed billing time and if so when in the day I need to add.
