The app allows your phone to detect the sound of clapping and run a loud alarm so you can easily find it.
Clap your hands and always find your lost device!
I wonder how it works being installed on two phones simultaneously. Or on every phone in a big family.
Simple&useful. I wish there were such things for TV remotes and my life would be complete.
None. As long as you don't have the "clap" light house control :D
