Solo engineering product
Built by one developer with modern map technology.
SunnyDaysApp is created by Leon Loncaric as an individual project from Salzburg, Austria. It combines official open geodata, OpenStreetMap-based vector data, terrain tiles, weather sources, Cloudflare tile delivery and a custom Pathfinder backend hosted in Europe.
The first target countries are Austria, Germany and Switzerland. More countries can be added later as the tile pipeline and data coverage grow.
