A app de marés gratuita que criei para o Garmin

Tides on your wrist, offline and free

If you spend time near the sea, the tide decides a lot of your day: whether the break works, whether the sandbank is walkable, whether your boat gets out of the harbour. Checking that usually means pulling out your phone, and phones and salt water are a bad pair.

So I built Tides for Garmin. It's free, and it puts the tide on your wrist.

What it shows

• The next high and low tides, with times and heights, for the hours ahead
• Tide extremes for the next 7 days, so you can plan the weekend, not just this afternoon
• A glance view, so a quick scroll from the watch face is enough for a check
• More than 200 stations worldwide, with optional manual station selection if the nearest one isn't the one you want
• Your choice of height reference: MSL, LAT or MLLW, plus optional tide coefficients

It works offline

This is the part that matters on the coast. Tide predictions are calculated on the watch, so you don't need your phone, a signal or a data connection. Raise your wrist on the beach and the numbers are there. (As with a few of the features above, this depends on what your watch model supports.)

It talks to your watch face

Tides shares its data with several watch faces, including Face It, Core, Goals, Goals 9, Titan and The Laziest Watchface Ever Created. If you use one of those, the next tide can sit on your watch face permanently, without opening anything.

Missing a location?

The station list keeps growing. If the coast you care about isn't covered yet, send me the location through the Contact Developer form on the store page and I'll look at adding it in the next update.

One safety note

Tides is for information, not for safety-critical decisions. Tide data can be inaccurate or out of date, so don't let an app on your wrist be the only thing standing between you and a rising tide. Check local sources for anything that actually matters.
