Whistler Free - Swing to call a friend! by Claudio Souza Mattos

Whistler

Release a strong and loud HEY!!!!

Whistle easily by giving your device a little flick in your hand.

Perfect for crowded environments like a cafeteria, mall, hotel, conference, las vegas (yeah!), and other areas where you need to catch someone’s attention but your voice just won’t cut it and you need something recognizable that stands out, like a powerful HEY, OVER HERE whistle right from your device!

A very useful app to keep it in your mobile device...
