A must have app for integration with Google Tasks – CalenGoo Calendar Review
This is the one. There are only 2 apps I've found that integrate Google Tasks in calendar view, and this is by far the better one.
Only complaint is that the day view requires portrait mode. I hope they allow layout to flow for landscape mode, which I use far more often with my iPad iStand.
