Ever got in a tricky situation and you need a friend or family member to come pick you up quick?
If yes, then Need U is the app for you!
Just set your emergency contact from those stored in your contacts, and hit the NEED U button.
It will send your friend or family member an iMessage or MMS message, including a map, coordinates, and nearest address requesting they come collect you from that location.
There is even a iOS extension for the app, so you can quickly access Need U even when your iPhone is locked (pass code still required if enabled on your iPhone).
