Today the app had been released in my home country, Germany. It gained some kind of attention, as I was sending out some press-kits to local (tech) blogs. So I got some users to start with.
This was the first time I launched a product for both mobile operating systems (Android and iOS) and eventually the first time ever making a real press-kit and sending it out. Lesson learned: Sending out press-kits is a must-have to get your app known to at least a few people, even knowing that only a small degree of the recipients will post a story or notice about the app.
