Yeah that's an issue. People have a good experience but forget to come back again. Maybe they're not sold on the value like transformational utility.

Meditation apps are a decent analog; it was years before they legitimately researched their own product instead of citing general studies on meditation and mindfulness. The sticking point for us is we want to stay out of your attention while you work, just support it with the neuro. So there's no a-ha moment like you see in vipassana or insight meditation, where the app is the focus.
