I used to love this app and recommended it to my colleagues. But now the history app does not function correctly (discussed in other reviews here). What is not spelled out in those reviews is that by attempting to add to the history tasks that were completed on earlier dates, the whole app hangs. The only way Ive been able to resolve the issue is to restart my iphone. Lame. Time waster. Boo.
