Tide, swell and wind at each of your spots, for your level, in one call: Worth it, Maybe or Not today, with the window and why. Pay once, no subscription.
Sendoa checks the tide, swell and wind at each of your spots, for your board and your level, and makes the call: Worth it, Maybe, Not today or Big for you. You get the window, and the reasons.
It's what you'd work out yourself with a tide table and a forecast open side by side, done for the next seven days.
YOUR SPOTS
All your spots on one screen, a call for each. You see which one is working and when to set the alarm. Tap a spot for the detail, hour by hour: swell height and period, wind, tide and light.
YOUR LEVEL
Tell it your board, your level and the biggest surf you're comfortable in. When it's too big for you, the call says so. Big spring tides and solid swell come with a warning about currents.
TIDES, EVEN WITH NO SIGNAL
Tide times and heights are worked out on your iPhone, so they still work in a parking lot with no signal. We check them against real tide-gauge readings and publish the error for every port on sendoa.app. 340 ports in six countries.
WHERE THE FORECAST COMES FROM
Swell and wind come from the Météo-France and ECMWF models. The source and the time of the run are on screen. Beyond three days, it tells you the forecast can still change.
WIDGETS
Your spot's call and its window on your home screen, the next tide on your lock screen, without opening the app.
227 SPOTS IN SIX COUNTRIES
France 74, Spain 50, United States 38, Australia 27, United Kingdom 26, South Africa 12. Each spot runs on local time, in your units: feet or meters, mph, km/h or knots. Spot missing? Ask for it from the app.
PAY ONCE
No subscription, no ads, no account, no trackers. Secret spots, an optional one-off purchase, lets you add your own breaks with the same forecast. They stay on your phone. Family Sharing covers both.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
The widget shows the first spot on your list, even a secret spot.
Spot screen: one tap on back is enough, even when you come from the widget. The buttons are no longer cut off.
My spots: hold a spot, choose "Change the order", then drag each spot into place.
