I have been playing with SenchaTouch 2 since the first developer preview. It has been a great framework to learn and a lot of fun. Today I'm happy to introduce you something I've built this past couple of months thanks to this amazing piece of software.
Currently the application is running on the 2.0.1 & we are working on a 2.1b2 port (that shows some nice perf improvements!). Will love to read any question/feedback you may have on this.
You might want to make it available to other countries in order to get any feedback. I can't install it ( google play) because it says I am in the wrong country. ( Netherlands.)
