One of the most useful

This is the app I have been waiting for for a long time.The latest version fixes all the problems I had with the earlier version. The battery life is acceptable. Both the calendar and location triggers work flawlessly. As a general rule, I do not have to even think about this app 99% of the time. It simply works.

Since the GPS is not perfectly accurate, you will get better results setting the radius of sensitivity a little larger than you would normally do.

Caviat: my phone use is light. If you are a heavy user, its possible that you will have problems with the battery running down before the day is out. Keep a charger handy.
