Earth
Open sea
Waves to the horizon. At dawn, by day, at sunset, in the blue hour, at night or on a silver sea; at night, with aurora or bioluminescence.
Guided breathing that follows the wave, no voice
Most meditation apps are a voice over a pretty background. Here there's no voice: the landscape moves at a breathing pace and you follow it.
Choose how
A mode, a length, a destination and a time of day. If you always use the same combination, save it as a ritual.
Follow the wave
The wave rises, you breathe in. It falls, you breathe out, and it leaves foam. On Mars the dust breathes; in Saturn's rings, the ice. The sound ebbs and flows with you.
End without a jolt
The session closes on a last out-breath, never in the middle of a hold.
Six destinations in three worlds: the sea, Mars and Saturn
Each destination is a real place with a name: its ground, its sky, its times of day and its sound. Tap «Watch it live» and the demo above takes you there.
Earth
Beach
Sand and shoreline: as you breathe in, the water moves up the beach; as you breathe out, it pulls back and leaves foam.
Mars · a dry sea
Acidalia Planitia
Dunes where there may once have been an ocean. Breathe in and the dust lifts; breathe out and it settles. At sunset, the Martian sun has its blue halo.
Mars
North Pole
Planum Boreum: layered ice cut by spiral valleys. The frost breathes: an icy haze rises and the horizon fades.
Mars
Jezero
The crater that once held a lake: loose rocks, the delta and the rim in the distance. In the sky, Phobos and Deimos.
Saturn
The rings of Saturn
You float above the rings, in silence, among chunks of ice. Saturn on the horizon, Titan in the distance and the Earth backlit.
Breathe, sail or sleep
Three ways to be in the same landscape, plus, on the web, a mode for focusing. The app's menus are in Spanish for now, so each mode shows its name there too.
Breathe · Respirar
The landscape sets the pace
Sessions of 1, 3, 5 or 10 minutes, or no time limit. Five patterns, and when you pause you can change the pattern, destination or time of day without losing the beat.
Sail · Navegar
No guide, just watching
A boat moves slowly across the sea; on Mars you cross the dunes like a rover. At the end, you see how far you went. 3 to 20 minutes, or no time limit.
Sleep · Dormir
Fall asleep to the sea
Pick 15, 30, 45 or 60 minutes: the waves calm down little by little, and at the end the picture and the sound fade out together, slowly. No bell, no summary screen.
For now, on Apple TV.
Focus · Foco
A star for every minute
The landscape stays in the background while you work, even if you switch tabs. Each minute adds a star, and the session draws a constellation you can name. Stop early and a cloud drifts by. Similar to a pomodoro: 5 to 50 minutes, with a breathing break after the longer ones.
On the web.
Tonight's moon
The moon in the sky has today's phase.
Waxing, full or waning according to the real date, and lit on the side you see from your hemisphere. No location needed: it comes from your device's date and time zone. It's only the phase: not where the moon is in your sky or when it rises.
On Apple TV now, coming soon to iPhone
The web version works today in any browser. The Apple TV app is on the App Store; the iPhone app is on its way. Both are in Spanish for now.
Apple TV
The sea on the big screen
Breathe, Sail and Sleep, with the remote. Free to download with Open sea and Beach; Mars and Saturn come with Pro, a one-time purchase, and you can try each destination for a minute first.
You download it from the TV: on your Apple TV, open the App Store and search for «Mar de Tranquilidad», the app's original name. It can't be installed from your phone or computer.

The app in your pocket
Everything the web version has, plus phone extras: it logs your breathing minutes to Apple Health if you turn that on, reminds you to breathe once a day, and gives a gentle vibration as you switch from breathing in to breathing out.
Coming soon to the App StoreGenerated live, no account, no internet needed
Generated live
Nothing is recorded: the code draws the landscape and makes the sound in the moment, on your device.
No account
No sign-up. Your minutes, streaks and constellations stay on your device, and on the web you can export them to move them elsewhere.
No internet needed
The web version installs like an app on your phone or computer and, once opened, works offline. Where the browser allows it, the screen stays on through the whole session.
FAQ
Do I need an account?
No. Open the app and start. No sign-up, no login.
Where can I breathe?
Six destinations in three worlds: Open sea and Beach on Earth; Acidalia Planitia, the North Pole and Jezero on Mars; and the rings of Saturn. Each one has its own times of day and its own light.
Is the app in English?
Not yet: its menus are in Spanish for now (its original name is Mar de Tranquilidad). The breathing itself needs no words: you follow the wave.
Is there an Apple TV or iPhone app?
The Apple TV app is out: on your Apple TV, open the App Store and search for «Mar de Tranquilidad». The iPhone app is coming soon. Meanwhile, the web version works in any browser, phones included.
Does it work offline?
Yes. The first time, it opens with a connection; after that you can install it and use it offline.
Does it have a voice or guided meditations?
No, on purpose. The landscape is the guide; if you want, a soft caption tells you when to breathe in and out.
Is it a medical treatment?
No. It's a tool to slow your breathing down and focus. It doesn't measure anything about your health and doesn't replace a professional.
