魚スイッチ - 釣り予報釣行プラン by UMINOTE helps anglers in Japan decide when and where to fish. The app converts tide tables, sea weather, and seasonal patterns into a single fishing-probability percentage and publishes a weekly ranking that highlights promising weekend options. Visual tide graphs, wind and wave details, a 900-plus spot map, photo-enabled logs, and method-specific checklists form the core planning tools. It targets recreational anglers and hobbyists who want a compact decision aid and a place to record catches.

How the app turns layered marine data into a single decision metric

The app reduces tide charts, sea weather and seasonal trends into a Fish Switch percentage, a single number intended for quick decisions. That percentage is derived from tide tables, wind and wave inputs, and historical catch records, and the tool also generates a weekly "Weekend Best Plan" ranking each Thursday to point users toward promising coastal locations for the upcoming weekend.

How mapping and spot management shape where you fish

The interactive map covers more than 900 coastal spots across Japan and ties into GPS spot management so users can save and revisit locations. The app requires an active internet connection for real-time tide and weather updates, and it runs on Android (and is available for iPhone). Map-based spot requests let the community suggest new locations for inclusion.

How daily routines fit the logbook, checklists, and alerts

Daily use centers on the photo-enabled fishing log and customizable equipment checklists for methods like sabiki or night fishing. The app sends notifications on days with favorable forecasts and organizes entries into a personal catch collection. The interface emphasizes visual graphs over dense tables, which helps anglers scan conditions quickly before leaving for a short outing.

What the app does with location and personal data

The app integrates personal catch history with forecast inputs to refine predictions for specific spots, and it uses GPS-managed spots for on-site recording. An active internet connection is required for tide and weather synchronization; the developer builds forecasting from both environmental data and user-submitted logs rather than relying solely on static tables.

To sum up, a practical planner for coastal recreational anglers

To sum up, 魚スイッチ is a practical option for recreational anglers in Japan who want a concise decision aid and a single place to track outings and catches; less suitable for anglers who need raw, multi-source datasets or a longer horizon without an account-gated tier. Use it as a quick pre-trip reference and a visual diary for recurring spots.
