Whistle Phone Finder is a free Android app developed by Techno_World. This app helps you locate your misplaced, forgotten, or lost phone with a simple whistle. If you often forget where you put your phone, or if your children misplace it, this app can be a lifesaver. You can even use it when you're in a hurry and can't find your phone. With Whistle Phone Finder, you won't have to ask people where your phone is anymore.

One of the best features of Whistle Phone Finder is that it's customizable. You can change the settings to run after a whistle is detected on your phone. You can also play the demo of all settings and switch on/off the whistle phone detection and flash. Additionally, you can change the mic sensitivity. The default settings are to play the ringtone and vibrate, but you can customize it as per your preference.

The app is designed to answer a simple question: where is my phone? It does this job perfectly and can save you a lot of time and hassle. However, keep in mind that the app includes some ads to offer it for free.
