On iPad, I honestly, truly do think that the web app, if saved to the home screen to very easily launch just like an app (per Safari share button at right of URL text field->Add to Home Screen), is generally superior to the native iOS app. And it’s good to go for landscape on iPad. Plus there are other features available there that are not on the native iOS app. Only thing I’ve found is periodically I need to kill the web app launcher when the initial splash screen doesn’t go away. I hypothesize that is when a new web app version is rolled out and the web app cache needs to be cleared by killing it. Anyway, try it out if you want landscape on iPad right now.
