Setting reminders and alerts based on a location isn't really anything new in terms of the underlying technology, but as we have seen so many times in the past, things seem to come to the forefront when large companies like Apple or Facebook adopt them and put them them back into the public eye. With the launch of iOS 5, Apple brought us the stock Reminders app that features location aware reminders and to-do tasks, but now thanks to the Location Alerts app for iPhone we also have the ability to schedule text messages and calls based entirely on location.
