I'm scratching my own itch: building a yet another audio signal generator for smartphone. I need some extra functionality that is not available elsewhere, and impose some limitations "just because": it must be bare minimal PWA.

But actual app does not matter, the main take away for me is: it is easy and fast to write bloatware (esp. with AI), but not that easy to distill to what is really needed. And what looked like a weekend project, a couple of hours max (with help of AI), now lingers for 2+ weeks on-and-off on evenings (of manual effort).
