I love the timer app and that it adds sessions to your calendar. But there are too many times where it needed to be reset. For example - even though Ive completed all my tasks the icon still shows up with the number 3 indicating that I still have 3 tasks due. Your calendar wont be updated unless you remember to go into the task and set the start time. I submitted a report in about a month ago and heard nothing back. Good idea, poorly executed and rarely updated.
