About WikiCatch

WikiCatch is an independent fishing app: a worldwide map of 325,000+ fishing spots, profiles for 4,894 fish species in 11 languages, depth contours covering the world's fishable water, and species-specific AI bite forecasts. It is built and maintained by one person — no content farm, no growth team.

Who makes this

I'm Akos Komuves, an independent software developer in Hungary and the founder of the app studio Tall Poppy. I've been building and shipping iOS apps full-time for years; WikiCatch is my main project. I write every line of the app, run the data pipelines that assemble the spot and depth databases, and answer the support email personally.

Where the data comes from

• Fishing spots — aggregated from OpenStreetMap water features, Wikipedia, and in-app angler submissions and ratings, then de-duplicated and verified against water geometry.
• Depth maps — assembled from public hydrographic sources including NOAA electronic navigational charts, ETOPO bathymetry, GLOBathy lake models, and national open-data programs, rendered into a single worldwide contour layer.
• Species profiles — compiled from scientific and encyclopedic sources, localized into 11 languages.

Posts on the blog are original analyses of this dataset. Every published number is queried from the live database — never estimated, never padded. When the data has a known bias (and geographic data always does), the post says so.
