The native app didn't help much. The biggest deal with the HTML5 app was adding DOM content as the user scrolled. They were experiencing memory leaks. The native app may have fixed that part, but their backend API service was still sucking pretty badly for months after that. Even now, on an iPhone4, the performance of the native app kinda sucks. It's better on a 5 or 5s, but still fairly slow to get a JSON stream, parse it and build dynamic views.
