I’m Karl-Ernst Kiel, an engineer exploring whether a solo developer with AI assistance can build and ship useful music apps on a shoestring budget.
I play keyboards in a band and occasionally drums. I use music apps daily — metronomes, ear trainers, setlist managers — and I have opinions about what they get wrong.
This blog documents the entire process: technical decisions, AI experiments, failures, and whatever comes out the other end.
