Just one day after launch, we were featured on AndroidAuthority.com and 2 days after that, we were on AndroidPolice.com and PhoneArena.com (All three are among the best).

So we did great at the launch, we are getting lots of new users and everything is going fine, for now!

What do you suggest for the next step? how can we maintain our ranking and what else can we do? (except buying ads)

here is our app:
