How Are You.............
Please Give Me Help How to Increase Review & Ratings For Android Apps
If the app is really good (serves the function as declared) and works in user friendly manner than the user would be happy to write encouraging review with befitting rating.
Though the app design may have interrupt (but not too often) to bring user's attention to write review and then the review window should open conveniently (without hunting/scrolling arroud)for user to write thereview/rating
You will get good reviews & rating if your app is bug free, interesting, user-friendly.
