Missing the most important feature
It doesnt run in the background, so it doesnt always remind you of tasks due until you go into the app to check. Its hard to see the point of a task app when it doesnt remind you to do the tasks. If all you want is a checklist, there are much cheaper apps for that.
It does have a bunch of other cool features, but I dont recommend buying it until they get that fixed.
