Ask HN: Has someone used Ruby/Python for Android/iOS development?

I quite liked the look of RubyMotion http://www.rubymotion.com/developer-center/ for iOs development (as I fancied using Ruby) but I cant say I have tried it - sorry.

Wasn't Instagram written in Python?

At Instagram, the backend, API and web applications are built using Python/Django but not mobile applications. They are made with native ios/android technologies.

Ah, thought so.

I was really hopeful of kivy [http://kivy.org/], but after playing around with it a little bit, it seemed very foreign to me, even though I program in Python daily. It seems very un-Pythonic, for lack of a better term.

On top of that, it seems to focus more on 3D than 2D, which is probably why there's so much there I'm less familiar with, but I mostly just want a decent 2D interface in Python.

I've had the best luck out of things like AppCelerator and Phonegap, but I've never been thrilled with the performance of either.
