Iam trying a tip i got from a friend that do apps...
Make small and simple apps and upload them while working on your larger projects

Wath he told me is that as long as they are not really awfull and i hope not

So will that build a small userbase and generate small amounts off add revenue

While you spend larger amounts on your larger project

But this could backfire if i upload to much to simple apps
