Finlore Guide replaces text-heavy dichotomous keys with six illustrated questions about physical features you can see while handling the catch. Each answer option presents a drawing rather than paragraph descriptions, allowing waterside identification without dry hands or reading glasses.
Every species plate displays a full-width painted fish with pinch-zoom detail, identification callouts that step aside when zoomed, and a circular calendar showing active months. Size comparison uses human hand silhouettes at true scale, while water layer icons reveal where each species typically holds during different conditions.
Catch limits, size regulations, and closed seasons deliberately excluded because they vary by jurisdiction and update annually. An offline copy would mislead users fishing across state lines or using last year's app version. Finlore Guide focuses on timeless biological traits that remain constant regardless of local policy changes.
Answer questions about body shape, dorsal fin type, mouth position, tail form, barbel presence, and coloring. All answers illustrated as drawings. Live species counter shows remaining candidates after each selection.
Calculate fish weight for 22 species using length and girth measurements. Optional girth input improves accuracy. Essential when scales unavailable or releasing fish quickly without stress.
Eighteen prepared species pairs displayed side-by-side with synchronized numbered identification markers. Roach versus Rudd, Chub versus Dace—quickly spot the diagnostic differences that separate similar fish.
Record species, location, length, water layer, and attach images. View personal season summary showing biggest specimens and species list. Export complete dataset as CSV or JSON for external analysis.
Six painted cross-sections illustrate where fish hold: the drop-off, sunken timber, weed edge, river mouth, back eddy, and wind-blown shallow. Learn why structure changes create feeding zones.
Full-width naturalistic paintings with identification callouts, typical and record size comparisons to human hand scale, active month ring, water layer preferences, diet information, and feeding times for all 48 species.
Finlore Guide requires no network connection, account creation, or data transmission. Every species illustration, identification question, and educational cross-section resides on your device. Catch logs and photos never leave your phone unless you manually export the data files. No tracking, no analytics, no advertisement networks.
