Know the water before you go
Maris Blue reads the wind, the waves and the water at the spot you fish, five days out, and shows you where fish may rise. All on one calm map.
Coming soon. Join the waitlist and we’ll send you one invitation to try it before release, and one note on launch day.
A coast drawn for fishing
Open the map and you’re already on the shore. Coastal Calm shows the water the way an angler reads it, by day and by night. Tap a lake or a river to see what the map knows about it, drop a pin where you want to fish, or save a stretch of coast for the days without signal.
Maps by Mapbox. Water details come from the app’s own data; where nothing is known, nothing is made up.

The week’s wind and water, at your spot
Wind and gusts, waves and swell, water temperature, pressure on the move, sun and moon, and the tides where they’re reported. Pick the exact point you’ll stand on and plan the morning the night before. Premium goes hour by hour where the data allows.
Forecast data from WeatherAPI, refreshed on a schedule through our own gateway. It’s a forecast, not a promise.

As the app showed it on 16 October 2026 for this point: a forecast for that day, not a live reading.
Fish Rise shows you where to start
Draw an area on the map and ask. Our server reads the forecast and the water around your spot and ranks where fish are most likely to rise, with the conditions behind every answer. It’s a score to think with, not a guarantee: it reads the water, not the fish.
Free shows you a sample. Premium runs the real analysis.

The scores the app gave on 16 October 2026 for one run. Low numbers are honest numbers: a quiet day is a quiet day.
The rest of a good day
Fishing Guide
Species pages that tell you where a fish lives, what it bites and when it feeds, with a tip from someone who has caught it. The guide launches with 16 species.

Four more things worth having in your pocket.
Saved spots
Drop a pin, give it a name, come back to its forecast later and share the coordinates with a friend.
Condition alerts
Set a limit for wind, gusts or waves at your spot, and we’ll send a notification when the forecast crosses it.
Offline maps
Download a stretch of coast before you leave the signal behind. What you saved keeps working out there.

Questions
When can I install it?
Not just yet, and we’d rather get it right than rush it. Join the waitlist and you’ll get one invitation to try the app before release and one note on launch day, nothing more.
Where does the forecast come from?
From WeatherAPI, through our own gateway, which caches it and refreshes on a schedule. Nothing on screen is live to the second: it’s a forecast, and the forecast disclaimer says what that means.
What is Fish Rise?
A score our server works out for the area you choose, from the forecast and the water around it. It tells you where fish may rise. It doesn’t promise you’ll catch one.
Does the map work without signal?
The regions you download do: open Offline Maps, pick a stretch of coast and save it. The forecast and Fish Rise still need a connection.
Which languages does it speak?
The app launches in 13 languages. This site speaks English and Turkish for now; the rest follows.
What does the waitlist store?
Your address, the version of the consent text, the time, the page language and path. No IP address, no device fingerprint, no cookies. Every mail has a one-click unsubscribe, and we delete the list after the launch announcement.
How do I reach you?
