FAQ
What kind of information does this app provide?
This app provides detailed tide and weather forecasts specifically for Japan. It includes tide graphs, hourly weather predictions for up to 7 days, wave information (direction, height, cycle), and optimal fishing times. It also offers weather maps and daily news relevant to surfing and fishing.
Is this app suitable for users outside of Japan?
No, the tide information is exclusively for Japanese locations, and the app uses the Japan time zone. While weather data is sourced globally, the primary focus and functionality for tides are limited to Japan.
How accurate is the tide data?
The tide graphs are calculated using 'Tidal anharmonic constant' within the app, meaning no external data download is required for tide calculations. This ensures immediate access to tide information for around 340 places in Japan.
What are the fishing forecast features?
The app can identify 'good times' for fishing, which are typically a few hours before and after high or low tide. In Japan, these are referred to as '上げ三分, 上げ七分, 下げ三分, 下げ七分'.
How can I see weather information for nearby locations?
The app utilizes your device's GPS function to identify nearby tide locations. Once identified, it can display the tide graph and weather forecast for that specific nearby area.
