This is a summary for all developers. I found these tips super useful:

  • Make a good app. doesn't have to be great, but not garbage.
  • Use your family and friends for first review and ratings.
  • Use review exchange networks, such as Reviewsmotion.com. This helps a lot.
  • Be proactive and ask your users to rate you.
  • Learn from negative reviews and improve your app.

Thats all! :-)

I hope it helps
