Re: Wasn't HTML5 supposed to fix all this?
rvt begins to answer the question: idots can't write great apps with zero effort.
A second problem is the Android legacy. The Android 4.0.4 browser really didn't perform well and made writing fluid apps tricky. (There were some hacks; but it will suddenly stall.) And 4.4 is the first version of Android to have threads so you were using the UI thread for everything (although I think the design of the threading API promotes good design). As of Android 5.0 the browser updates independently of the OS. And latest versions of Chrome perform really well; there's no trouble.
Similarly Apple were slow in providing a decent javascript engine. (The app would run faster in Safari than as a standalone app because Nitro was only available in Safari.)
But I'm doing polynomials with hundreds of terms and the performance is fine on a modern OS. And Animation is great if you use the new APIs.
