It grew organically. Initially I made the app as an experiment, just wanted to see how planets rotate and align, and what makes people interested in that. That became the foundation. Then somebody asked “can I have some extra asteroids and minor bodies added?” This became the first add-on I have introduced. Each time I can think of an interesting feature, I think “is there enough standalone value to classify it as an add-on?”. The app is organically growing using the methodology of having the core and extensions. Family sharing? I never really looked into that. I had maybe two requests over the years. It’s just a different kind of user base.
