I was really happy with another to-do list app (List n do), but it did not sync very well between my iPhone and iPad. So I began looking for a to-do list app that had all the features I need (setting tasks far into the future, repeating tasks at different intervals, syncing, etc), and Teed comes the closest. In fact, in my opinion, its almost perfect. The only thing keeping me from giving it 5 stars is that it doesnt sync automatically. I have to manually sync every time I do anything so that when I pick up my other device, it is in sync. Id also appreciate the ability to email myself a task, or post one to my calendar, but these are bonus features and not really necessary, but would be nice. Im sure auto sync will come eventually, and when it does, I will certainly update my review to 5 stars!
EDIT: Im seriously thinking about taking another star off because of how often it asks me to rate the app...even though I already have. Really annoying. UPDATE: Im taking my rating down to three stars because of this. The app prompts me to rate it just about every time I open the app. It only takes a second to say that I dont want to rate it (again...), but I shouldnt have to. I HAVE rated the app. I like the app. But this needs to be fixed.
