Whistle Phone Finder PRO is the best Android Finder (Phone Locator) application found on Google Play which has helped many people locate their Android device with just a simple WHISTLE after losing it, forgetting it somewhere or being hidden somewhere in a room on a desk behind papers, in a briefcase or in a coat pocket etc. The app was already downloaded over 3 Million times!!

ATTENTION: Please find some important features in the latest version release v4.27 such as custom ringtone (melody) selection (MP3 or M4A files), lower battery consumption, less advertising, smaller download package, improved whistle detection, and optional haptic feedback at whistle detection event!

Here are the main features of the new Whistle Phone Finder PRO 4.27:
Whistle Phone Finder PRO contains now the Battery Guard feature which can be configured to disable Whistle Android Finder enabled if the battery level drops below the predefined value!

Whistle Phone Finder PRO can be enabled or disabled under the settings tab. Simply run the application and the settings tab will appear! Remember: Whistle detection is working ONLY when the device is sleeping (i.e. when the screen is OFF).

Once enabled, Whistle Phone Finder PRO will truly work "forever" even if you reboot your Android device! Of course, you can disable it under the settings tab at any time.

Whistle Phone Finder PRO integrates the ability to release the microphone of your Android device during incoming or outgoing calls or when the screen of your device is ON! After a call ends, the normal background operation of whistle detection will resume automatically.

It is possible to choose among 5 different whistle detection sensitivity levels! Whistle Phone Finder PRO is just ready to adapt to any Android device regardless of the specifics of integrated acoustic components.

Under the Whistle Phone Finder PRO settings tab it is possible to choose among 18 different very amusing audio notification sounds to notify the presence of the detected whistle! Furthermore, Whistle Phone Finder PRO includes now the option to select your own customized notification sound! Just select any of yours MP3 or M4A music file and use it as notification sound! Once your whistle is detected, the Android device will respond to your whistling with playback of a selected audio notification signal. Furthermore, the display of a "sleeping" Android device is illuminated in order to easily locate your device in your bag or in a dark room for example. Under the preferences tab a user can also select (and approve) the usage of maximum possible volume for audio notification regardless of current media volume settings. However, Whistle Phone Finder PRO is designed to resume your current media volume when audio notification is not played.


Whistle Phone Finder PRO is based on sophisticated but computationally optimised Digital Signal Processing (DSP) techniques to analyse captured audio signals from the environment and search for distinct time-frequency patterns of a typical human whistle. The incorporated DSP algorithm is not signal energy based, therefore this whistle detector is much more accurate and reliable than similar applications found elsewhere on Google Play.
