Don't sleep on Reddit.
I used to hate Reddit, but honestly I got over myself.
Used it promote yaps.ai (best-in-class dictation and note-taking software that works offline) and it single handedly brought in about 300 downloads across 2-3 days. Several reviews and led to 50+ helpful 1-on-1 conversations with end users.
It's definitely been an eye opener. And it's great, even if you don't have a large audience.
Reddit works best when the thread already contains the exact pain. For Kinetic Override I get much better signal from specific Android no-root auto-clicker / macro-recorder / idle-game tap-fatigue discussions than from posting a generic launch pitch in broad startup spaces.
