What's New in Tideline

2.3

August 17, 2026

New in Tideline Pro Custom Alerts. Set your own line and get told when the water crosses it: tide height, wave height, wind speed, or water temperature. You can also be told a set time before or after high and low tide, or before the current turns to flood or ebb. Up to 10 alerts across your saved locations. Tap any day in the forecast to open its full tide curve, out to 30 days. Drag across the chart to read the predicted height at any hour, not just the high and low times. New for everyone Tomorrow's full tide chart is included. Tap tomorrow in the forecast and drag across the curve to see what the water is doing at any hour. Hide the cards you don't use. Conditions, beach hazards, currents, swell, sun and moon, and best fishing times can each be switched off in Settings. Tide height, the chart, and today's highs and lows always stay. A map button in the location picker, so browsing stations by where they are is easier to find. Fixed Searching a beach or harbor by name now searches every NOAA station instead of a short list, so places like Fort Popham turn up properly. Better contrast in low light. Text on the lower part of the screen was washing out against the background. Apple Watch: the tide chart no longer draws flat after the app has been in the background, and conditions refresh when you raise your wrist rather than waiting for a relaunch. Rip current risk and National Weather Service beach warnings are unchanged and stay available to everyone.

Best tide app for divers

I’m a PADI OWD certified scuba diver based out of Key West. I’ve found this app incredibly useful for tracking the tide for dives and other maritime activities. It’s sleek, easy to use and provides all the information I need without being cluttered. I would recommend this app to any diver or sea lover!
