Mad Thinker turns every fishing trip into fisheries data. Wild fisheries are under pressure — and anglers, guides, and field researchers see things scientists rarely do. Mad Thinker captures what they see, with the rigor needed to actually use it. AI-verified catch records One photo identifies the species, estimates fork length, and logs environmental conditions. Every record is geotagged, timestamped, and researcher-reviewed before entering the dataset. Research-grade data, captured in seconds. Beyond the catch Record wildlife sightings, habitat conditions, water quality notes, and operational incidents — so the full picture of a fishery lives in one place, not scattered across notebooks and group chats. Built for the backcountry Works offline — no signal required for water-body and station lookups Tides, weather, and moon data for every river and shoreline you cover On-device photo analysis for privacy and reliability in remote areas A platform for fisheries partnerships Used research programs to standardize catch and observation data across watersheds. Configurable to your rivers, your species, and your reporting requirements.
