Built an isochrone-based neighborhood analyzer for Korea (no real-estate listings)
Most real-estate sites in Korea push listings. I wanted the opposite: a pure neighborhood analyzer without listings or ads pushing properties.
What it does:
- Pick any address in South Korea
- Choose walk or transit mode
- Slider: 10 / 20 / 30 / 45 min radius
- See subway stations + 8 facility types (school, hospital, mart, park, gym, pharmacy, library, cafe) reachable inside that isochrone
- AI summary in natural language
- 100-point composite score
- Transfer-count breakdown (0/1/2 transfers) for transit mode
Freemium: 5 free runs/day, 9,900 KRW/month Pro for unlimited.

Stack: Flask + Leaflet + OSRM (walking graph) + public transit data + custom isochrone overlay.
How do you deal with the fact that the osm coverage and quality is not yet where it could be for korea? Do you have any auxiliary sources?
I guess it isn't a deal breaker when you're focused on the seoul area...
