Store description excerpt
Look at a photograph and name the fish. Four choices, one answer. Every fish you get right joins your own field guide. 800+ SPECIES, ALL REAL PHOTOGRAPHS From tuna, sea bream and yellowtail you would meet on a dinner table, to deep-sea oddities and reef fish of the Ryukyu Islands — over 800 species of the fish found in and around Japan, every one shown as an actual photograph with the photographer and licence checked. THE NAMES PEOPLE ACTUALLY USE The same fish changes its name as you travel. Japanese amberjack is wakashi → inada → warasa → buri in Kanagawa, but tsubasu → fukuragi → gando → buri in Toyama. Pick a prefecture on the map of Japan and you get the fish of those waters together with the names used there — 46 of Japan's 47 prefectures are covered, shown in Japanese with romanised readings. THREE LEVELS Well Known (94 species), Enthusiast (403) and Professor (367). Each level draws only from its own pool, so beginners and specialists both get a real game. DAILY QUIZ AND RANKINGS Ten questions a day, the same ten for everybody. Fifteen seconds each, faster answers score higher. Today, this month, this year and all time. REVIEW Every fish you miss is remembered, and you can run a quiz made only of those. Get it right and it graduates off the list. ALSO Pinch or tap to zoom any photo. English and Japanese, switchable at any time. Share your results and collection progress. The field guide and map work offline. Species notes are written with the look-alike species checked side by side, because the hardest part of naming a fish is telling it from its close relatives. Photographs come from Wikimedia Commons and iNaturalist under licences permitting commercial use and modification (CC0 / public domain / CC BY / CC BY-SA). The map of Japan derives from MapSVG (CC BY 4.0). Photographers and licences are listed in the app under Settings > Photo & map credits.
