Indeed. Supporting a single platform means generally fewer bugs and headaches, as multi-platform is going to introduce new troubles regardless of how one goes about it. Approaches that try to be write-once-run-everywhere “silver bullets” will still see platform—specific bugs, as will per-platform codebases.

It’s not a coincidence that macOS/iOS has long had a disproportionally large quantity of high quality indieware. Capable framework + minimal headaches = polished apps that an individual or small group can sustainably support, even within less profitable niches and without VC funding.
