yoruneko is a quiet place to work.

Meditative ambient music, made to be listened to for hours without wearing thin. It sits behind your work, your study, or your last hour before sleep.

■ Five moods, five worlds

Focus — sharp air, nothing in the way.

Relax — the hours after the work is done.

Meditation — stillness, nothing moving.

Sleep — the last light before the screen goes dark.

Journey — somewhere far from here, still moving.

Each mood carries its own track, its own film, its own balance of sound.

■ The moon is the real moon

A 3D lunar sphere built from NASA surface data, tracking the actual phase of tonight's moon. It waxes and wanes with the sky outside your window.

■ A focus timer that stays out of the way

Set your own focus and break intervals, run as many cycles as you need. Your focused hours are recorded quietly in the background — today, all-time, and the last seven days at a glance.

■ Layer in the room around you

Ten ambient sounds — rain, waves, wind, a running stream, a crackling fire, birds, night insects, a distant town, thunder, and a singing bowl — each with its own volume. Some play continuously; others, like thunder and birdsong, arrive now and then, the way they do outside.

Add as much or as little as the hour calls for.

■ A background that knows when to step back

Turn the video off for a calm, solid backdrop, or dim it to just the right level.

Every track is made for this app under the yoruneko project.

Open it, let it run, and work.

■ A focus timer that stays out of the way

Set your own focus and break intervals, or simply let it count up while you work. Your focused hours are recorded quietly in the background — today, all-time, and the last seven days at a glance.
