Only being able to control devices from a mobile phone, and only one running specific OSs with specific app stores, is a silly restriction that hampers the utility of the product.
It would be far better if you escaped the jailbreak of mobile OS and app stores and extended the product with webapp that runs on a browser in any device (laptop, computer, other mobile OSs, etc.) -- that would also future proof the service. I would definitely use it immediately (work PC, Kindle, etc.)!
