Smart Tide: Tide Chart & Times

Know what the water is doing before you get there. Smart Tide reads tide predictions straight from the agencies that publish them — KHOA in Korea, NOAA in the United States, and the Canadian Hydrographic Service — and puts them on your phone, lock screen, watch and home screen. No account. No sign-up. No analytics, no ad networks, no third-party SDKs of any kind. A CHART YOU CAN READ AT A GLANCE The day's curve fills the screen, with high and low marked where they actually fall. The background follows the time of day, so dawn looks like dawn and night is easy on your eyes at 4am. Press and hold anywhere on the curve to read the exact height at that moment. FIND YOUR STATION ON A MAP Start from the map, not a list. Pan to your stretch of coast and the stations are there — thousands of them across Korea, the United States and Canada. Search by name, or let the app find the closest one to you. Saving a station never yanks you to another screen; the map stays where you left it. Korean stations can be searched by 초성 or by romanization, so both 부산 and "busan" get you there. ON YOUR LOCK SCREEN, LIVE Start a Live Activity and the next high or low sits on your lock screen and in the Dynamic Island, with a small chart showing where the day is heading and dots marking the turns. Set it to start and end on its own for the hours you're usually out. WIDGETS AND APPLE WATCH Home screen widgets in several sizes, and complications for the watch face. Ask Siri for the next high tide without opening anything. METRES OR FEET, CELSIUS OR FAHRENHEIT One setting, and the app, the widgets and the watch all follow it — including alert thresholds, so nothing is left reading in the wrong unit. IT WORKS WHERE THE SIGNAL DOESN'T Tide predictions are astronomical, so they can be computed rather than fetched. When there's no bar at the shoreline, Smart Tide falls back to harmonic constants stored on the device and keeps showing you the curve. SUN, MOON AND CONDITIONS Sunrise, sunset, moonrise, moonset and the moon phase for the station you're looking at. Where the agency publishes them, water temperature and wind readings too. FOR KOREAN WATERS KHOA also publishes surfing, fishing and mudflat indexes, shown alongside the tide for Korean stations. SMART ALERTS Get a notification when conditions line up — a spring tide, warm water, wind picking up. Smart Tide only offers the alerts a station can actually report, so you never wait on one that was never going to arrive. SMART TIDE PRO The app is free and stays useful free: the chart, the map, every station, widgets, the watch app, Live Activities, Siri and offline mode are all included. Pro adds three things — the full 10-day forecast instead of 3 days, unlimited smart alerts instead of 1, and unlimited saved stations instead of 3 — as a monthly or yearly subscription, or a one-time lifetime purchase with Family Sharing. BEFORE YOU RELY ON IT Tide predictions are forecasts. Wind, pressure and storm surge move real water away from them, sometimes a long way. For navigation or any decision where being wrong is dangerous, use official charts and notices. Smart Tide is not affiliated with KHOA, NOAA or CHS.
