Kiran Prasad (via Aaron Hillegass):
We have definitely shifted from HTML5 to native. The primary reason for that is, we’re seeing that more and more people are spending more time in the app, and the app is running out of memory. It’s not performance issues, like speed or rendering, but it’s still a big problem.
The second reason we’ve gone native is trying to get some of the animations — the spinners and the way they work — getting that smoothness, we felt like we needed native to really do that well.
