About Tidemark: NOAA Tide Widget
Tidemark puts the next high and low tide on your Lock Screen, Home Screen and StandBy, from the official NOAA predictions. It is for anyone who plans a day around the water: a beach walk, fishing, surfing, kayaking, boating, clamming, or getting off the dock before low water. Every widget is included. All six sizes ship in the app: Lock Screen rectangular, circular and inline, Home Screen small, medium and large, and StandBy at night. Each widget keeps its own station, so two coasts can sit on one screen. Nothing is behind a paywall. Pay once. No ads, no audio ads, no surveys, no subscription, no yearly data packs. Official NOAA CO-OPS predictions for 3,270 US tide stations, heights on the MLLW datum. The station list is built into the app, so search works before you have a signal. A seven-day table of every high and low, and a curve you can scrub to read the tide height at any minute.…
