Found this on XDA and thought you guys would find this useful. I've tested it a little bit and kind of like it.
Set tasks and be alerted when you are near/at a location. Easy enough to set up and it uses either GPS or cell triangulation.
Seems like a very practical app - Sometimes when I leave home to head to work, I think that I should stop and get gas, if this app works as promised I can set it to go off as I am approaching the gas station to remind me
Give it a shot. You can set reminders to expire after a time
I made one just to test at home and almost as soon as I finishes I got the notification.
