Although Ionic is faster than other frameworks I used, like jQuery Mobile it still feels slow and laggy compared to native applications (approx 5-6 times slower). Especially transitions and long lists feel kind of choppy and the framerate drop is quite noticeable even on today’s high end devices.
We are currently moving an existing app from ios/android to html5 using ionic and the difference in the user experience is very noticeable; especially on older devices using animated transitions is a no-no.
We are currently looking at alternative ways to speedup the app; this has lead us to famo.us and the famo.us/angularjs project that seem to promice to solve the rendering speed problems and still keep the AngularJs part of the project in the mix. I do not know how easy the transition would be or if it can be used with the ionic framework we love so much (that would be a match made in heaven).
Experts, what is your oppinion? Anyone tried it?
