SurfTideΔ for AppleWatch Manual


You can see tide information on your AppleWatch with SurfTideΔ v1.3.1.
You should use WatchOS6 or later.

To use the SurfTideΔ for AppleWatch, you should synchronize the tide data with “Send tide data to Watch” from the app settings.
When the synchronization is completed, the tide data can be shown on your watch alone. You don’t even have to connect your watch to the network.

Sync procedure


It cannot be used unless the watch and iPhone are paired. Click here for how to pairing.

At first, launch the “SurfTideΔ” with your watch. Next, launch the “SurfTideΔ” with your iPhone, and open the setting screen.
If it is possible to synchronize with your watch, “Send tide data to Watch” will be shown in green color, so tap it to synchronize.

Data cannot be synchronized unless your watch “SurfTideΔ” is launched near your iPhone.

The tide data to be synchronized will be the 5 most recently shown on the app. Since synchronization is manual, please synchronize manually whenever this information changes.
After synchronization, the tide information can be shown on the watch alone.

You can select the place by tapping the menu icon at the bottom of the screen. The watch remembers the last shown tide place.
