Shipping AI Harp to the App Store with Vibe Coding

AI Harp is now live on the Apple App Store, and this project became one of the clearest examples for me of what “vibe coding” is actually good at.

I did not build it the old way, with a giant spec, weeks of planning, and a fixed roadmap. Instead, I built it by moving fast, testing constantly, and tightening the product through many small iterations. One moment I was improving practice feedback, the next I was fixing App Store metadata, tuning screenshots, removing a paywall, adding localization, or adjusting audio behavior so the sample track would still play in silent mode. The product emerged through rhythm more than ceremony.

What surprised me most was that vibe coding is not really about being sloppy. It only works when you stay brutally practical. You still need to review details, test on real targets, clean up edge cases, and answer App Review questions clearly. Apple does not care that your product was built in an intuitive, high-speed way. It still has to behave like a serious app.

The most satisfying part was seeing how quickly an idea could turn into something real: practice flows, on-device AI features, multilingual support, App Store assets, privacy pages, and submission readiness all came together in a much tighter loop than traditional development usually allows. The feedback cycle was short, which meant product decisions stayed alive instead of getting buried in process.

Shipping AI Harp taught me that vibe coding is not the opposite of engineering. At its best, it is fast intuition backed by constant correction. You follow momentum, but you earn the finish by tightening everything that matters.

Now it is live, and that feels good.
