Forget about your daily tasks. Create alerts based on a location, associate a message or an image and don't worry about it anymore. AlertMeWhen will notify you when you're walking, running or passing by car before you arrive to the location. It's up to you to decide whether to ignore, snooze or pause it.
It's possible to setup accuracy and efficiency (using GPS and network) in order to avoid an excessive battery usage, however AlertMeWhen is smart enough to limit the number of updates and to send notifications only if you're really getting close to your target. When you're still or you don't want to receive any alert, you can simple switch off the background service and the application will quit completely. It's also possible to set permanent and one-shot alerts on specific days and time periods.
