As you know there is already an android app, written in native Java. 
I would like to provide also apps for other platforms like iOS and
later on maybe even Windows but I am reluctant to write them all on
different code bases. I would much rather prefer to use a mobile
framework, having to write and maintain only one code base and then
compile them into android IOS and so on.
I already had a look into Phonegap  and Ionic  but it turns out
the app written in it starts too slow.
I also heard about Facebook React native  and Appcelerator Titanium
 but I do not know more about them.
Does anyone of you have experience with them or with mobile apps in general?
If yes, I would appreciate if you contact me or just respond to this
email into the mailing list.
