OFFLINE TIDES, WORLDWIDE
Harmonic Tides predicts the tide on the watch itself, from the harmonic constants of 2,653 tide stations in 113 countries. The complete data set travels inside the app. No phone, no internet, no account, no subscription. It works offshore, abroad and years ahead.

WHAT YOU SEE
• Now: height above chart datum with direction and rate per hour, a 24 hour curve with every high and low water, and a countdown to the next tide.
• Tide table: all high and low waters of a day, the range, spring or neap, sunrise and sunset. Any day from 1902 to 2037.
• Water window: set a depth and see when the water is above or below it and how long it stays.
• 30 day calendar: the daily range with the moon phases.
• Station: distance and bearing, type of tide, mean range, HAT and MSL, data source and the air pressure hint.

WITHOUT OPENING THE APP
• Tide alarms before high water, low water or a water window, each with its own lead time.
• A glance with height, direction and the next tide.
• A complication for your watch face, for example "HW 12:52".

FIND YOUR STATION
Nearest station by GPS, the ten nearest as a list, favourites, recent stations, or a station by number or coordinates. Up to 8 own ports with time and height corrections. Height datum LAT, MLLW or MSL.

MADE FOR 82 GARMIN WATCHES
Laid out for AMOLED, MIP and the Instinct with its subscreen. On Instinct 3 Solar and Instinct E, own ports are set up in the app settings on the phone, and harmonics and compare are not available.

10 LANGUAGES
English, German, French, Spanish, Italian, Dutch, Portuguese, Danish, Swedish and Norwegian. The app follows the language of the watch.
