"The app works surprisingly well. Now a sentinel crow sounds an alarm when I walk out of the office (I dont even need the app anymore!)" - from a real app user
This app contains audio that crows do not like, at all. And no, we are not talking about accordion music (although we have not tried that yet). You can play the audio from the iPhone as long as the crows are close enough to hear it.
The app also contains everything you wanted to know about crows. It will inform, educate, and ultimately help you scare them away.
Also included is a chat area so you can share stories and other ideas to try.
Crows have a good memory: make sure they see you playing this. Sooner or later they might fly away when they see you, without using the app.
The app is fun to use, and it sure beats standing up and clapping your hands at a bird, while it just looks at you as though you are a crazy person.
