This question is an exact duplicate of:
Is there any official Stack Overflow Android app?
Other than the Stack Overflow apps in Google Play which are nothing more than web browser type apps?
Why is the official Stack Overflow for Android app still not developed?
There is a real need for this app, since its not very user friendly to login from a browser on pc/tab/phone to view the questions & answers.
More importantly to get real time notification and increase portability.!!
