Why a second screen

Built for focus, not for feeds.

Most ways to fill a second screen end up competing for your attention, always nudging you toward the next thing. TideGlass does the opposite: it moves with the music you already chose, and asks for nothing in return.

Made for deep work

Calm motion at the edge of your vision keeps you in flow, and asks for none of your attention. It stays light on the CPU while you work.

Nothing to fall into

It is not a place you browse. Nothing to scroll, nothing queued up next. Just the audio you chose, made visible.

Calm on tap, day or night

Reading after dark, or hosting on the big screen. The room turns to soft, glassy light that never breaks the vibe.

Watch the app breathe.

Short screen recordings of TideGlass in everyday use, from first launch to picking a mood. Real captures arrive with launch; the scenes behind them are already live.

First run

From zero to calm

Grant system audio, pick a first mood, and you're running a full scene in under a minute.

It reacts

Felt, not metered

Play something with a pulse and watch the sea answer. The reaction is smoothed, never strobing.

Pick a mood

Worlds, not presets

Choose "Night Shoal," not "FFT bin gain." Crossfade between worlds, or let them rotate to match the music.

Eighty-eight worlds.

Every one is a living simulation with its own rules, never a loop and never a preset. Weather moves through them, creatures hunt in them, light travels across them, and whatever you are playing stirs the whole thing. Here are eight.

  • Oceans & Rain
  • Forests & Fields
  • Night Lights
  • Deep Space
  • Skies & Peaks

On the same screen

Two companions in the corner.

A second monitor can earn its place twice over. Both of these sit in a corner, fade out when you stop moving the mouse, and never cover the world.

What is playing, right there

Cover art, title and artist for the track you have on, with skip and pause under your cursor. You can put it in any corner, size it, or have it show only when you reach for the mouse.

Works with Apple Music Spotify

A focus timer that fits the room

Work and break intervals you set once, a soft bell at each turn, and a row of dots for the sessions behind you. It lives in the same calm as the world it sits on, so a finished session never yanks you out of one.

Set it once. Let it breathe.

How it works

Built to be felt, not watched.

No bars, no equalizers, no kaleidoscopes. Sound maps to nature, and the design gets out of your way.

  1. 01

    Nature, never knobs

    Low sounds swell the tide and breathe through the dunes. Bright ones scatter starlight. You never see a parameter.

  2. 02

    Slow inertia

    The motion breathes with the music instead of twitching at it. Nothing strobes, nothing snaps, nothing demands a glance while you work.

  3. 03

    Dark by default

    A second monitor sits at the edge of your vision all day. Palettes stay deep and low-glare, as easy on your eyes at noon as at midnight.

  4. 04

    Set and forget

    Beautiful in under a minute, then invisible. Send it to a second display and leave it running.

Coming soon

Bring the tide home.

An ambient companion for your Mac, reacting to whatever's playing right now.
