How one user comment shaped my latest update, and why I’m building the next one with beta testers

I’m a solo dev working on Oasis, a sound app for focus, sleep and relaxation with 3D audio and binaural tones. The latest update came almost entirely out of user feedback. The biggest change started with one comment: someone said the end of a session matters as much as the start. Oasis used to just stop, so I rebuilt sessions with a slow fade-out and a gong. Along with that came timed sessions, a simpler UI and lock screen widgets. Building this way has been the best marketing I’ve done. People who see their feedback in the app stick around and tell others. Next up is an adaptive mode, and I want a group of testers shaping it from the start. If you want in, comment or DM me and I’ll send the TestFlight. Here is a link to the appstore if you want to test the app.
