CloseReview for Provider for Google Calendar by shgysk8zer0
Rated 4 out of 5 stars
With the latest update, Google Tasks finally works! It also allows multiple calendars and task lists to be setup at once.
Only 4 stars though despite the improvements because offline support seems to have been removed.
