4 stars: This is a fantastic app and was a life saver when I lost my phone in public, it works surprisingly well but the reason why I give it a 4 star intead of a 5 is multiple reasons yes but mostly because when my phone is completely off, meaning shut down, and then re - opened the app, the activation whistle button turns off. Please make it an option to be kept on after you turn your phone back on.
5 stars: The app is good, but there is also a mistake that if any sound comes, the tune starts ringing. It would be better to just recognize the voice of the owner of the mobile and then ring
5 stars: Very helpful! Can only recognize a whistling sound performed volontarily, which is good! Rather than other similar apps that keep making the phone ring after every sound
3 stars: This app is good but not best because it works only when my mobile is switched on . It does not works when my mobile is switched off. It is important that it should works when mobile is switched off. Okay!
3 stars: Smart mode is not functioning as it should be. The phone is responding to multiple sounds on my phone. please fix the problem it's a great app.
4 stars: Nice app i would suggest that the display of the botton at the top of the phone and on the screen saver should be optional preferably hidden so someone wouldnt gain access to turning it off at will for security purpose against theft thanks.
5 stars: experience is great with whistle app thank's for all about who design it ...
