This is a free clapping app to find your device in a specified area.

We all have a story about how we lost our phones. In a crowded place, noisy environment, or while we were traveling. It's pretty easy to misplace a smartphone in a big building.

There are plenty of ways to find your phone. Some of them work better than others.

We've built a simple but effective tool to find your phone without relying on GPS or other mobile devices. It's a combination of a sensor and a free app.

The sensor is an internal component that works with your phone's built-in microphone.

We've built our app in such a way that it works even if the phone is in silent mode. If a clapping sound is detected, the phone alarms with a flashlight and vibration.
