How It Works

How it works

Your tides, weather and alerts on one small screen

Tidesy is a display for your home that shows what the water is doing at your beach today. It's set up for your coast before it ships and keeps itself up to date.

No appIt's a display. Glance at it, like a clock.
No subscriptionBuy it once. It keeps working.
Official dataTides from NOAA, alerts from the National Weather Service.
Getting started

Three steps, and only one of them is yours

We set it up for your coast

We use your shipping address to pick the nearest NOAA tide stations and tune your tide levels to your water.

You plug it in

Connect it to your home Wi-Fi from your phone. That's the only setup you do.

It takes care of itself

Tides, weather and alerts stay current on their own, and new features arrive automatically.

What you'll see

Two views of the tide, plus alerts when they matter

Tidesy Detail view for Los Angeles: the day's tide curve with alerts, live water level, rain, waves, UV and daylight

The whole day at a glance

A smooth curve of today's tide, with a marker showing where the water is right now and whether it's rising or falling.

  • Today's highs and lows, with times
  • Current temperature and wind, and any active alerts
  • On touchscreen models, tap any point on the curve to see that hour's tide
Tidesy Large view for Los Angeles with big tide numbers and current conditions

Big numbers across the room

The next highs and lows in large digits, plus the tide right now. Easy to read from the kitchen or the couch.

Tidesy can switch between both views on its own, or stay on the one you like.

Your own tide levels

Mark the tide you like best, say a low enough tide for a walk to the point, and a level that's too high for the beach. Tidesy shades those hours so you know when to go.

We set sensible levels for your beach before it ships. Change them anytime from your phone.

Weather alerts, in plain view

When the National Weather Service issues an alert for your area, like a high surf warning, coastal flood advisory or small craft advisory, Tidesy shows it on screen with what, where, when and how serious.

No alerts, nothing extra. Just your tides.

It looks after itself

Always current

New data arrives on its own, all day. If the internet drops, Tidesy keeps showing the day's tides and catches up when it's back.

Quiet at night

The screen dims, or turns off, during the hours you choose.

Gets better over time

Software updates install themselves over Wi-Fi. No cables, no SD cards.
