Once you lose an object, open the app and clap your hands close to where you last saw it. The program uses sound detection and the microphone on your phone to study the clap's echo and loudness, leading you toward the item with visual and sound signals.

Yes, provided the person or pet carries a smartphone or wearable device that has Clap2Find installed and Bluetooth turned on. If they clap, your phone receives a signal, allowing you to locate them through sound triangulation.

Make sure the microphone is not blocked and you are in a quiet place. Clap firmly and try different distances. If the problem continues, adjust the app in settings or check for background noise that may interfere.

Clap2Find is free, with optional in-app purchases for extra features. Basic clap detection works without the internet by using your phone's sensors, but an internet connection is needed for cloud-based sound mapping and for sharing lost item alerts with other users.
