3.) Pitch to tech blogs


4.) Social Media


5.) Create a video channel on YouTube or Vimeo


6.) Create a referal program within your app


7.) Grow your subscriber list

What type iOS app? Game, utility, services support, health,...?

8) word of mouth, a variant of 7).


9) buying ads in online magazines


But of course, don't use the forum to do it.
