What Homekit lacked
Homekit implementation is left to developers, making it less user friendly than what I would expect from Apple. Home fills the gap with a full implementation. It is a very good application to manage all your Homekit enabled devices. Clean interface, and not mentioned but Siri is supported. If there is any shortcomings, its more due to the lack of maturity of Apples Homekit than to the developer who is very responsive.
