Shipped my first iOS app. No downloads. How to get the first download?

I just launched my first iOS app. Padelsmile, an iOS app for running Americano/Mexicano padel tournaments. Built solo in SwiftUI, took several months, got rejected by Apple 3 times before finally getting approved.

The app is live but now I’m facing a harder problem. Finding real users. Padel is a niche sport but growing fast in Europe.

For those who’ve shipped indie apps. Wwhat actually worked for getting your first 100 users? What would you do differently?

App is free to try if anyone’s curious: https://apps.apple.com/us/app/padelsmile-padel-tournament/id...
