Sand Mandala: Bowls & Sleep,
Play, listen, breathe, sleep
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Play Tibetan singing bowls and watch sand draw their sound. Breathe with the sea, drift off to rain or whale song, and wake to a gentle dawn.
Sand Mandala is a place to come back to when you need to slow down.
Strike a Tibetan singing bowl and listen as its sound blooms and slowly fades. Above it, sand trembles and draws a different figure for every note: the real physics of sound, made visible. Each bowl is synthesized live, so no two strikes ever sound quite the same.
PLAY
Eight bowls tuned to G, ready to play — no rules, no sheet music. Strike them softly or firmly with felt, leather or wood, or let one sing on its own as the mallet circles its rim. Record what you play and listen back whenever you like. And if you want to look inside the sound, See the Sound shows its partials live, how they beat, and the figure two notes draw together.
LISTEN
A library of melodies written for the bowls: just listen, learn them by following the sand, or play along. Make your own playlists to drift from one piece to the next hands-free.
BREATHE
Turn on Breathe with the Scene and everything breathes with you: the waves roll in as you breathe in and draw back as you let go — six breaths a minute, no counting, no effort. Just follow along.
SLEEP
Eleven scenes to wind down the day: the sea under the moon, rain on the glass, a distant storm, fireflies in the woods, plankton glowing on the shore, a pond with its bamboo spout, a fairy forest, a campfire, the northern lights over a frozen lake, whales singing under the sea — and a sunrise to wake to. Every scene answers your bowls. Choose how long it plays and let it fade out on its own as you fall asleep.
WAKE
Alarms that ring with singing-bowl melodies, and a sunrise that comes on gently. They work with Siri, Shortcuts and widgets.
FOR WHEN IT'S HARD TO STOP
When your mind won't quiet down at night. Before an exam or a difficult conversation. After a heavy day. On a night that feels long. Sand Mandala asks nothing of you: no goals, no streaks, no minutes to hit. Just a quiet place to play, listen and breathe.
FREE AND FULL
Free, with no ads and no time limit: all eight bronze bowls, See the Sound, six melodies from the library, three recordings, the Sea, Rain and Pond scenes with breathing, 15- or 30-minute sleep timers, one alarm, and Siri, Shortcuts and widgets.
Sand Mandala Full — one purchase, yours for good, shareable with Family Sharing: every melody, unlimited recordings you can export, playlists, the other eight scenes, more bowl materials, 45- and 60-minute sleep timers, until the alarm or all night, unlimited alarms with any melody, more awake with every snooze and a separate weekend schedule. No subscriptions. No accounts, and nothing leaves your iPhone or iPad.
Sand Mandala is a relaxation tool, not a medical device, and it is not a substitute for professional help. If you're going through a hard time, talk to someone you trust or to a health professional.
