'Tap' is a new app that claims to be the fastest messaging app in the world. It allows iPhone and Android users to share their location with friends and contact them simply by tapping the phone twice. This unique feature works whether the phone is in your hand, on a table or even in your pocket.
The app allows you notify friends when you've arrived at a particular location or when you want to inform them that you'd like to meet up. All notifications sent by the app disappear after ten minutes to reduce the risk of clutter caused by lots of notifications.
Tap is not the first app of its kind; however it's biggest selling point is that it is the fastest messaging app that uses tapping.
