About Still Water

Still Water is a calm space for breathing exercises, guided meditation and sleep. Check in with your mood before and after each session, build a gentle streak, and keep a short journal of reflections.

Is Still Water free?

Yes. Every breathing exercise, four meditations including Anxiety SOS, a sleep story, the white noise and sleep sounds mixer (white, pink and brown noise, rain, ocean, fan, wind, fire and birdsong) and the silent timer are free, with no ads and no account. Still Water Pro is an optional one-time upgrade ($4.99) that unlocks the full meditation and story library and 10 to 20-minute sessions.

What breathing exercises are included?

Box breathing, 4-7-8, coherent breathing, the physiological sigh and Relax 4-6. A glowing orb grows as you breathe in and softens as you breathe out, with optional voice cues.

Who narrates the meditations and sleep stories?

Sessions and stories are original scripts read by your device's built-in voice, over a soundscape you choose. With Still Water Pro, many meditations also come in 10, 15 and 20-minute versions.

Can I mix my own background sounds?

Yes. The Sounds tab mixes white, pink and brown noise, rain, ocean, fan, wind, fire and birdsong, all made live in your browser. Save your mixes, play one under a meditation, and set a sleep timer that fades everything out gently. Still Water Pro adds a stream, distant thunder, crickets, a heartbeat, a soft hum and a night train, unlimited saved mixes and 90-minute and until-morning timers.

Does Still Water play white noise and brown noise for sleep?

Yes. White, pink and brown noise are free, along with rain, ocean waves and a fan. Each is generated live in your browser and loops without a gap, and the sleep timer (15 to 60 minutes free) fades it out gently.

Is there a plain meditation timer?

Yes. The silent timer is unguided, with bells to begin and end and optional interval bells along the way.

Is my data private?

Yes. Your mood check-ins, streaks, sessions and journal stay on this device with no account. You can back them up to a file and restore them later.

About White noise

White noise has the same energy at every frequency, which is why it sounds like a bright, even hiss, like an untuned radio. Because it covers the whole range of hearing, it is good at hiding sudden sounds, a door, a voice, a car, that would otherwise catch your attention. Still Water makes it live in your browser rather than playing a recording, and it loops without a gap.

How to use it

  1. Press Play in the card above. Browsers only start sound after a tap, so nothing plays until you do.
  2. Set the Volume, or tap other tiles to mix in more sounds. Each tile has its own slider.
  3. Set a sleep timer (15, 30, 45 or 60 minutes) if you'd like it to fade out gently on its own.
  4. Like the mix? Save mix keeps it on this device, and Share copies a link to it.

Keep this tab open while it plays. iPhone and iPad may pause web audio when the screen locks: tap the moon for Sleep mode, a dim, near-black screen that keeps the sound going, and keep the phone on charge.

Good for

  • Covering a partner's snoring, traffic or a neighbour's TV at night
  • Sleeping somewhere new: a hotel, a dorm, a long-haul flight
  • Blocking out an open-plan office or a busy café while you work
  • Giving naps the same sound wherever you are

Questions

What is the difference between white, pink and brown noise?

White noise has equal energy at every frequency and sounds bright, like a hiss. Pink noise falls by 3 dB per octave, so it sounds softer, like steady rain. Brown noise falls by 6 dB per octave and sounds like a deep rumble.

Should I leave white noise on all night?

You don't have to. Set the sleep timer to 15, 30, 45 or 60 minutes and the sound fades out gently at the end. Keep the volume low and comfortable.

Is it free?

Yes. White noise and eight other sounds are free with no account and no ads. Still Water Pro, a one-time upgrade, adds six more sounds and longer timers.
