PRIME to AVOID in seconds.

Stop guessing from a weather app. Eddy scores every water body from PRIME to AVOID by analyzing real flow rates, water temperature, and forecast data — not crowdsourced reports.

Dropping pressure means fish are feeding.

Generic weather apps ignore barometric pressure trends. Eddy tracks pressure changes by the hour and tells fishermen exactly when the bite window is opening — before it starts.

Your best window. Down to the hour.

Eddy doesn't just score right now. It scans the next 72 hours and tells you exactly when your best window opens — the specific block of time when conditions peak for your activity.

Snowmelt and tides change everything.

Mountain rivers run cold, fast, and murky from upstream snowpack — not rain. Coastal paddlers need tide and current data not just wind forecasts. Eddy tracks upstream snowpack, NOAA tidal data, and real-time flow rates so you understand why conditions are what they are — and exactly when they change.

Wind at 12mph kills a paddle session.

Eddy weights wind speed, direction, and forecast trends specifically for water — so you know if conditions improve or deteriorate during your window, not just what they are when you leave the house.

Moon phase drives the bite.

Serious anglers know the solunar calendar. Eddy calculates major and minor feeding windows from moon phase and position — so you know if the morning tide aligns with a major feed before you back the boat down the ramp.

Not a fishing app. A water intelligence system.

Catch logs and social features are noise. Eddy is a conditions intelligence system — built for the angler who checks pressure trends before bed and the kayaker who needs to know if Saturday's flow is runnable before booking the shuttle.
