Yes. The Ocean world is completely free, with no account, no sign-up and no time limit — open the site and it plays. Two extra worlds, Forest and Space, are unlocked with a single one-time payment if you want more.
Instead of playing a recorded track on repeat, the app generates the sound live in your browser. Shapes drift across the screen, and every time two of them overlap a note, texture or drone is born. Nothing is pre-recorded and nothing ever repeats, so the music can run for hours without the loop fatigue you get from a playlist.
That's what it was built for. The sound has no lyrics, no beat to follow and no sudden attacks, so there is nothing for your attention to latch onto — it stays in the background while you work, study, read or code. Many people use it the way others use brown noise or rain sounds, but it stays musical instead of turning into static.
An optional switch under the worlds. The same sounds become a slow, soft groove that keeps changing. Free on Ocean for 8 minutes at a time; endless in every world after purchase.
No. It runs in the browser on desktop and mobile, with nothing to download and no account to create. On a phone you can add it to your home screen and it opens like an app. On iPhone that also gives you pause and play on the lock screen.
Ocean is deep and underwater: whale calls, sonar pings, slow tides in the low register — it's the free one. Forest is warm and still, built from temple bells, singing bowls and soft mantras. Space is calm and futuristic, made for long focused work: a deep steady hum, warm analog pads, and soft electric-piano notes and short signals that drift past and echo away into the distance, with plenty of room between them. Each world has its own sound, palette and set of instruments.
One payment unlocks Forest, Space and endless Rhythm forever, including future updates. No subscription. You get a key by email that works on every device, and Ocean stays free either way.
Yes. In the unlock window press “Listen for 30 seconds” and the world plays for half a minute, so you can hear it first.
In crypto only, through NOWPayments — cards are not supported. You can pay with USDT, USDC, BTC, ETH, SOL and hundreds of other coins. The network takes a few minutes to confirm, and your key is emailed right after.
Each press of the pay button starts a fresh payment, so you can simply try again. Crypto payments sometimes fail on the wallet side: not enough left for the network fee, the wrong network, or an invoice that ran out of time. If money left your wallet and no key arrives, write to [email protected] from the email you used and we will sort it out.
It arrives by email as soon as the payment is confirmed, usually within a few minutes. Check your spam folder first. If it still isn't there, open the unlock window, enter the email you paid with and tap “Lost your key?” to have it sent again. Still nothing? Write to [email protected].
Yes. Open the email on the other device and tap the button, or paste the key into the “Already have a key?” field. The key belongs to you, not to a single browser.
If you paid and the key never arrived or does not work and we cannot fix it, you get a full refund. Write to [email protected] from the email you bought with. More in Terms, refunds & privacy.
On iPhone, yes: the sound keeps going when you lock the screen or switch to another app, and it plays even with the silent switch on. Add the site to your home screen and the lock screen gets pause and play. On Android it depends on the browser.
Yes. Next to the volume there is a sleep timer. Pick from 15 minutes up to 90 minutes and the sound fades out and stops by itself.
Yes. The world you chose, the volume and the number of objects are remembered on that device, so it opens the way you left it.
The sound is synthesised on your device, so once the page is open it keeps playing even if your connection drops. You do need to be online to load the page the first time.
Almost no data — there are no audio files to stream, just one page. Battery use is similar to any animated page. The page asks the screen to stay awake so the sound isn't interrupted, but you can lock the screen whenever you like and the sound goes on.
Each shape is an instrument. Circles are textures, squares are harmony, triangles are living creatures, bars are the drones that set the tempo, and diamonds are percussion. Sound only happens when shapes overlap — drag the Objects slider to make the field busier or sparser.
No account is needed. Your email is kept only if you buy, to send your key. Visits are counted anonymously, with Google Analytics cookies and a simple counter of our own. No ads, nothing is sold. Details are in Terms, refunds & privacy.
It's a solo project by Max Ramozov, a designer who builds things in code. No team, no venture money, no ads and no tracking beyond anonymous analytics — the paid worlds are what keep it running.
Free Rhythm plays 8 minutes at a time. Unlock for endless Rhythm, plus Forest and Space.
One payment, yours for good. No subscription.
