Current clarity first
Eddy is built to make current timing, direction, and local flow patterns easy to read over the entire coverage area. Not just at specific points, not just in a narrow time window, but everywhere and all the time.
Current charts made easy
Tidal current charts for every kind of boater.
WorkingTidal.ca builds tools for boaters who care about local conditions, timing windows, and clear, accurate current information. The first product is Eddy, the current chart app designed to make complex tidal flow easy to understand.
The philosophy is simple: less clutter, strong offline behavior, and software grounded in real boating use.
Offline-native
The app architecture centers on prebuilt atlas data, on-device rendering, and no internet connection required.
Built on the water
WorkingTidal.ca is focused on software shaped by real boating use, not generic dashboards made far from the coast.
Meet Eddy
A current-chart app for every boat.
Eddy is built around one job: helping boaters understand what the water is doing, where the flow will run, and when a passage window is worth paying attention to simply and easily. No looking up tide tables, no deciphering complex charts, no guessing. Just a clear, visual picture of the currents around you, on your device.
The current app design centers on prebuilt atlas data, on-device rendering, point-current support, and optional location-aware map features. That foundation makes it a better fit for practical field use than websites that disappear the moment coverage gets thin.
- Offline atlas assets and on-device rendering built for field use.
- Schedule-driven current views backed by precomputed current datasets.
- Point-current support for station-based current lookup and visual trend context.
- Optional device location and heading overlays.

Eddy is built as a practical current-visualization tool. It should not be treated as a substitute for official charts, notices, instruments, or prudent seamanship.
