If you've ever missed an important message then Priority SMS is for you! Specify a keyword and Priority SMS will trigger an alarm on your phone when a new message arrives containing the keyword. You can even choose to override silent mode to ensure you read the message ASAP.
NotiSync is a very simple application that allows you to forward notifications from one device to another! Never miss another text message or phone call while you're on your tablet. Whether your phone is in your pocket or in another room, NotiSync will make sure you're notified. Try it out!
Set a destination, and Location Notifier will notify you when you get close! If your transit system isn't yet supported by Google Maps, you can use Location Notifier to notify you when your bus stop is approaching. For long highway trips where you don't need turn by turn navigation, have Location Notifier notify you when you near your exit.
