this Thread is mostly for Developers.
A little bit about me:
I use BBLOG all the time and I really like the concept of extending the functionality of a product by third parties. I am currently working on RocketTools, which is a server administration platform for Battlefield (launching soon!) and I am going to develop a mobile app for it as well.
The Battlelog App for mobile phones is kinda bad. The reason for this is , that it's a hybrid app which simply doesn't perform good enough. It is a website essentially.
Since everything on Battlelog runs via JSON Endpoints, writing 3rd party software is actually not too hard.
So why not implement a mobile app based on ReactNative which has the openness of BBLOG?
This thread is simply a starting point for a discussion if it would actually be possible to manage something like this (from a technical and legal standpoint). The project would be OpenSource to be transparent on the authenticating handling, as users need to log in with their credentials and of course to be open to improvements.
I am currently very busy with other projects, but I might start this one when I have more time, as I would love to see a quality app for Battlelog.
