Ummm.....
Response from developer
Thank you for reviewing. A clarification, you don't actually need to AFFIX the phone to the door, just place it against the door. The app was meant as a security aid for families with small children or people travelling alone, particularly at night when people are sleeping, especially because many new properties have accessibility guidelines which require any exits to be unlocked and opened with a simple turn of a handle. If you don't have small children and don't travel alone, then your negative review is understandable, and we apologize for the inconvenience. Currently we sell the app, as opposed to giving it away for free, because the product is not compatible with advertisements or with in-app purchases, and we weren't comfortable providing a security product missing any features. Apple will give refunds if you contact them, you can indicate you bought the app by accident. https : // www [dot] imore [dot] com / how-to-get-refund-itunes-app-store
