Amazing!

I do not know why so many frustrated people with this app. I use it with stereo receiver HK3770 and for me works any time. Layout of remote is better than original supplied with receiver and I actually do not use it anymore. I have the app installed on all iPhones/iPads at home and they always connect and work flawlessly. Once in a while initial recognition between receiver and app fails, but all you need to do is to close app, then open it again and - voila!
