You can load up your games in a recent mobile browser or package them into APKs with the Intel XDK (we didn't have a chance to test iOS export yet since we don't have an iDevice but it should work). Performance-wise, I don't have hard numbers or anything. This is the Web, you won't get as much perf out of it as a native app, but the games we've built so far run great.
