famo.us is a javascript framework using which you can develop apps in javascript which can give the native feel. Their website looks pretty decent on phone. You can explore their examples. I guess cordova compilation should work for famo.us apps too.

I've seen famo.us too. Same comment as my one for Ionic. The website for famo.us has some pretty good demos, but I'm looking for a launched app that actually uses it.

We at Digital Green need an SMS based data collection tool as well as mobile solutions for low cost devices. Any tech which is user friendly and seemlessly work in online and offline would be awesome to have too. Please contact sreenivasula@digitalgreen.org for further communication

i don't see any link on your pages to them, so just saying.. i wonder if kobo toolkit, open data kit, and related projects are of any use to you..

We tried using open data kit but because of lack of expertise we could not roll out the product.
