Hi. I also like React a lot. But after couple hours of research, I decided to go Angular + Ionic for my mobile app.
The big problem is: whatever framework you choose, you have to decide the app architecture: do you want your mobile interface be in the same project with your web app (if you already have one) and build using divided package modules, or do you want to build a completely separate app and connect to server using DDP (Asteroid) or REST.
You could find reference here
To me, after reading this issue on Github, I have been building a separate mobile client app, with:
- Meteor backend server ( share with my web client app )
- Angular-Meteor by Urigo installing through Bower (ver 1.3.2 now with helpers support)
- Ionic
- Meteor client side package by Idanwe installing through Bower ( with this package, I dont have to use Asteroid and still have full Meteor API in my mobile client app).
Till now I’m very happy with the result 
. Looking forward to have more feedback from you guys.
