Eventually I pushed it forward (thanks to the Unity Engine at the time) and made it a "real" app on the App Store. As others have noted, there's a large gap between bespoke, home-cooked software and commercial choices. As a full-time developer this was a side-project and still suffers, imho, as an under-invested commercial app. The app has had very modest success (pays about the equivalent of one espresso a week) but I still love it.
When an app is "just yours" there's an aura of fun about the project that can get stripped away when the trajectory becomes more commercial.
