I am challenging myself today, been struggling for many moons with how to word this without being aggressive, and it seems impossible: you have a persistent blind spot about the efficacy of iOS. It's virtually impossible to launch iOS-only today without enough funding that you can ride out the ensuing 1-2 years to also now build out and staff a web app, etc. IIRC you have a distaste for that sort of funding (which I share)
The old Mac indies have brand names and a benefit of a smoother transition since they were there before the App Store. You and your partner were both influencers in the Mac indie community dating back *2 decades* now, and benefited greatly from the visibility of that: didn't Apple have Halide on the Apple Store phones at some point?
It's very, very, very, hard to get to market, get attention, and get to a competitive wage in the US, just on UX and an iOS app, even with a year or two of patience.
