Hello, HN! I wrote a good application (I made it for myself, as I could not find a ready-made application with the necessary functionality), uploaded it to Google Play, users like the application madly, excellent ratings and reviews, of course Google reacts adequately, gives the first users and slowly gaining 100K+ downloads, then 200K+....

After a while, I make an application for Apple at the request of users, upload it to the App Store, almost no downloads. I started to feel a little sorry for the time spent, I wondered how to promote it for free? )
