Of course web apps aren't ever going to be as fast as a native application (especially on iOS because Apple deliberately hampers performance for web apps) but they're by no means a hopeless cause. A HTML5 web app might take a little while longer to develop, but it'll work out cheaper than building an iOS application. LinkedIn to this day remain the perfect example of how to build a straight-up HTML5 mobile app that performs beautifully.
