A digital whistle for your phone
Whistle Android is a very simple app that allows us to use a mobile phone as a digital whistle. In addition, it features different types of whistle with sounds that can be configured by the user.
Three whistles in one
The Whistle APK app is characterized by its simplicity, making it very easy to use. All we have to do to access the whistle menu is to open the app and watch an ad.
Three whistles on one app.
Next, the interface will show us three whistles and various red buttons formodifying the sounds and frequencies. According to the developers, these whistles have three key functions:
- Calling for help.
- Dog whistle.
- Classic whistle.
We are free to change the whistle at any moment and even modify the sound frequency. However, although we can download Whistle for free, free use of the app is limited. Specifically, we have to watch an ad to unlock all the whistles and we can only access the platform for a total of60 minutes. Therefore, it may not be the most practical solution for requesting help in dangerous situations, although it does feature two SOS buttons.
Requirements and additional information:
- Minimum operating system requirements: Android 4.4
- Offers in-app purchases.
