WHY TIDELINE

Knowing when high tide is only gets you part of the way. Tideline answers the question that actually matters on the water: what is it doing right now, and what will it be doing when I get there. Tides, currents, swell, wind, and beach hazards in one place, with every number labeled with where it came from and how far away.

NOAA-POWERED ACCURACY

Every tide and current prediction comes directly from NOAA's Tides and Currents service, the official source for US tide predictions. Wave and sea temperature data comes from the NOAA National Data Buoy Center, and beach hazards from the National Weather Service. No third-party guesswork, and every card names the station or buoy it read.

DESIGNED FOR THE WATER

Whether you're timing an inlet, planning a fishing trip, checking the surf, launching a kayak, or walking the flats at low water, Tideline shows you what you need to know quickly and tells you honestly where it came from.

PRIVACY

Tideline doesn't collect your data. Location stays on your device and is used only to find the nearest NOAA station. There are no accounts, no tracking, and no analytics.

Built in Maine by one person, for anglers, boaters, and surfers.
