Zoonote

And this app is a continuous testament to all those dynamics: it has no ads, no subscription (unless warranted due to recurring costs per user), no account (no personal info ever stored), no user analytics or telemetry or tracking that phones home or a third-party vendor, no intrusive popups or notifications, no dark patterns, no psychological hooks with ulterior motives, no upsell, no premium tier. All it is, is very straightforward: to simply exist, solve a unique problem (with my skin in the game), do it well enough all-around that people would pay for it, new features in the app are built solely based on user feedback, and be happy that close to 100 users are using my app every day!
