Fishing App Ideas Survey

What is useful for Thornapple

Open source apps mostly teach capture workflows. Paid apps mostly sell prediction, map layers, and community density.

The strongest borrow is not a social feed. It is a private field workflow that ties a catch, miss, lure, weather, water level, sonar signal, and return plan together with almost no typing.

Ideas worth testing in Deeper

One-thumb event capture

Borrow from logbooks: log the event in one tap, then let species, lure, photo, and note be optional follow-up fields.

Thornapple change: promote Miss and Ignore to first-class learning signals.

Structure-first map layer

Paid apps make contours and private waypoints feel central. Deeper should treat scan signals as the primary map vocabulary.

Thornapple change: show holes, ledges, cool pockets, access, snags, and catches as comparable layers.

Local condition score

Forecast apps package confidence into one simple rating. We can do a more honest version tied to river gauge, water temp, season, and catch history.

Thornapple change: explain why a spot is ranked instead of inventing fish probability.

Return-plan route

ANGLR-style waypoints plus self-hosted analytics point toward a trip plan: revisit these structures, in this order, under these conditions.

Thornapple change: generate a 5-7 stop kayak plan from sonar signals and notebook outcomes.
