I have been knocking my iPhone 5s for the past 10 minutes, but nothing is happening. On my mac, it seems that everything has been setup correctly, I can see my iphone name in the unlink button, so everything must be set up correctly. On my iPhone 5s, I see my personal icon for my macbook Pro retina 13'' and a big picture of a macbook pro. I have been knocking everywhere in my iPhone: the picture of macbook pro, my macbook pro personal icon, the white spaces around the app, my home screen, notification center, my locked phone, and nothing seems to happen. I understand that you are trying to make this as simple as possible, but things you assume to be obvious might not be obvious for others. For example, where do I knock? Does the phone have to be awake? Does the app have to be open? etc. Also, your app seems to be failing silently. I have been knocking all over the place and it would help tremendously if there was an alert telling me what had gone wrong. That way, I can email support and pinpoint exactly what is wrong. As of now, I have no idea why your app is not working. edit Finally figured out what I was doing wrong. Put your phone flat on the table. Then tap twice on your phone and you should see rings show up on your macbook pro. Your phone can even be locked. Do not hold the phone in your hands while you tap it. I was holding the phone in my hands before, which causes the taps to fail to register.
