Totally relate to the OP. I recently got my app kicked out of Apple App store for not being updated to the latest SDK. No patience or time to change programming language. layout engine, audio API, graphics, screen sizes etc. I just said "screw that" and now point people to a crippled-but-usable web version of it instead when they ask. My app is 5+ years old and I basically considered it "done". It came to be exactly how I wanted and nothing more .. and users kept discovering new possibilities even after years of usage. It's a metronome https://talakeeper.org https://talakeeper.org .
