—— WHY TIDELINE Tide apps tend to be cluttered or overwhelming. Tideline takes a different approach — a clean interface, government-grade data, and widgets that put your next tide on your home screen or lock screen. —— NOAA-POWERED ACCURACY Every tide prediction in Tideline comes directly from NOAA's Tides and Currents service — the same data used by the US Coast Guard, NOAA charts, and professional mariners. No third-party guesswork. —— DESIGNED FOR THE WATER Whether you're planning a fishing trip, checking the surf, launching a kayak, or timing a beach walk, Tideline shows you what you need to know — fast, accurate, and beautiful. —— 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. —— Tide predictions are for general planning. Always consult official NOAA charts and local authorities for navigation.
