No backend, no analytics, no paid tier, and the story of accidentally becoming a developer while building an app for Kyoto's under-visited 80%. Hi Dev.to. First time posting. Pretty nervous. I grew up in Kyoto. I built a free iOS app called Kyoto Unknown that lists the under-visited 80% of the city.
