WordUp

If you get separated from friends at a festival, concert, or other crowded place, WordUP makes finding them and being found as simple as raising your hand. Just type in your name or a special word that your friends will recognize, select a color scheme, click the display button, and hold your phone up above the crowd where it can be seen from a distance. The colorful display acts as a beacon to people who’re looking for you, pointing them to your position.

Don’t get lost in the crowd. Raise your arm, fly your digital flag, and get found again.
