"Tidal Current Check" is an app for checking tidal currents (direction and speed) in areas such as the Akashi Strait.
When you open the app, you can instantly see whether it's a rising or falling tide, the current speed in knots, and how many minutes are left until the next slack tide (current change).

■ Main Features
・Current Current: Displays the rising/falling tide and current speed (knots) in large font. The direction is displayed using the same current name as the Japan Coast Guard, such as "Northwest Current."
・Slack Tide Countdown: Displays the remaining time until the next current change.
・Tidal Current Graph: Uses the same style as the Japan Coast Guard's tidal current prediction graph. Overlay display of current change/fastest current markers and tide level (tidal gauge data)
- Current change/fastest current time list: Displays a numbered list of current change (slack tide) and fastest current times/speeds for the day.
- Tide name badge: Displays spring tide, neap tide, spring tide, neap tide, and young tide.
- Weather band: Displays weather, temperature, and water temperature for each time period at the top of the graph.
- Current change alert notification: Notifies before slack tide (daily/"Today only" mode available for fishing days only).
- Date navigation: Switch to previous and next days to anticipate the tide cycle.
- Offline support: Displays the last acquired data even when out of range (acquisition time is clearly indicated).

■ Supported locations (more to be added sequentially)
- Akashi Strait (Buoy No. 2)
- Tomogashima Strait
- Irago Strait
- Nakayama Strait (Mouth of Mikawa Bay)
