What is the best way to promote a Mobile App? Share your opinions.
Suggest to your friends or co-workers. And get them to download it. Once you get some download you will obviously rank better in App Store and hence more downloads.
In my opinion you don't need to promote separately. Just get some downloads and app store will do that for you.
