I whistle: Phone Finder

If you have ever lost a phone in your room, bag, desk or car and you couldn't find it; this program is just for you. This application detects sounds similar to whistling and then informs you about the location of your lost phone. You only have to whistle and your phone will start vibrating, emitting a loud sound and shining a bright camera light of the phone. This way you can quickly locate your lost phone!
How does it work?
Start the application. Choose the way in which your lost phone will inform you about its position. You have to choose:
- sound: Choose the notification sound which will be played when the phone is found. Beside the kind of played melody, you can also set volume of played notification to maximum to hear your phone from afar.
- torch/light: An application will start the flash lamp of the camera, which will make finding the phone easier and faster.
- vibration: The telephone will start vibrating at the moment of whistle detection.

Additionally you can set listening out for the whistle only while the screen of the phone is off. This will help save battery.

This tool also detects the moment of incoming connection. This option will unblock the microphone used to detect a whistle when the phone receives a call.
After the phone call, the phone will continue listening out for the whistle.

Important! Please whistle clearly and quite loudly. The effectiveness of whistle detection depends on built-in microphone and number of noises and sounds of surrounding.
