What's New in Smart Tide

2.0.0

September 11, 2026

Smart Tide goes global, and gets a new name. NEW NAME "Tide Current" read as tidal current — the horizontal flow of water, which this app has never claimed to compute. It's Smart Tide now. NEW: THE UNITED STATES AND CANADA Thousands of NOAA and Canadian Hydrographic Service stations join the Korean ones. Pick your source, or search across all of them. NEW: FIND STATIONS ON A MAP Station discovery starts from the map instead of a Korea-first list. Saving a station keeps you where you are rather than throwing you to another screen, and your saved stations sit in a row along the top of the map. NEW: METRES OR FEET Switch height, temperature and wind units in one place. The app, the widgets, the watch and your alert thresholds all follow. NEW: KOREAN, ENGLISH AND FRENCH Fully translated, with Korean station names romanized so they read properly in every language. Regions now say which country they're in — "West Sea" alone was not much help outside Korea. FIXED: alerts that could never fire You could set a surfing alert on a station that doesn't measure waves. It would simply stay silent forever. Smart Tide now only offers the alerts a station can actually report, and says why when one isn't available. FIXED: Live Activities disappearing One you started by hand would be shut down a moment later by the automatic schedule. It now leaves your manual ones alone, refreshes more reliably in the background, and leads with the next high or low rather than a current height that could go stale. FIXED: Siri failing on US and Canadian stations "What's the next high tide?" returned "station not found" for anything outside Korea. FIXED: long station names breaking the saved list Names like "Redwood Creek Marker 8" wrapped and squeezed the tide reading onto two lines. ALSO A redrawn chart with a full-width curve and a background that follows the time of day. High and low points marked on the Live Activity chart. Confirmation before deleting a station that has alerts attached. Nearest-station lookup no longer suggests a station on another continent.

No Canadian tides locations

Don't use this app in Canada it only have US and Caribbean locations only

Useful features and interface, with room for some improvements.

Current features work great. It is nice that a map of the location is provided in the small window, but it will be nice to provide a map with all of the tide points, available, near the person's location.

That's way, the person can choose their preferred location before heading to the area as noted on a map.

Exactly what I needed

Simple and easy to use. Like the ability to add favorites to a list. Would like to see a search by map option.

Beautiful app!

Finally a good looking tide app. However, tide times are only available in UTC and you can't change. Confusing to try to figure out what time it is every time. Please update in the future to change to current time zone or at least the time zone the station is in. Great app!

Does not work for SF.

Looks pretty but doesn't work other than apparently Hawaii as advertised.
