This worked immediately for me and is very responsive. Overall, it works better than the physical remote. The two things I like better on this app than on Rokus app is that the channel icons are better laid out here, and the IP entry.
But the main screen, where most of the action takes place is not very attractive due to the ugly menu bar at the top. Theres a large keyboard icon that could be a small icon of a single key (Roku uses a noticeably smaller keyboard). And there it is, "Remote", right at the top where you cant miss it. But you dont need it. Its completely obvious that you are looking a remote. I guess the purple menu bar is there because its Rokus color brand, but even Roku uses an understated gray bar, not purple. The less attractive interface is why I dinged it one star.
Less is more.
