Bow-wow Patrol

This app aims to reduce damage caused by vermin such as wild boars and weasels. It uses a timer to periodically play the sound of a dog barking at night when vermin approach fields and houses. It is expected that the vermin will be scared of the sound of the dog and run away, and that they will remember the presence of the dog and not come again.
Since the app will be running all day, we expect you to reuse old iPhones that you no longer use. You will also need an external speaker to make the sound louder. Please be considerate so as not to disturb your neighbors.
We hope that this app will be effective and useful, but we cannot guarantee it will.
Please note that you can only patrol a limited number of times at first, but the limit will be lifted if you purchase the function.
