Ambient that follows the hour.

Grain generates the sound as it plays. It is not a recording, and it does not loop. The mood follows the time of day. Highs stay soft for long listening. A focus timer is free. A sleep timer comes with Unlock. No account and no tracking. Any browser: Mac, Windows, Android, Chromebook, and iPhone.

Every theme includes 30 minutes of free play each day. Unlock removes the daily limit and adds the sleep timer, full screen, lock-screen playback, and offline install. All future themes included. A web Unlock will carry over to the Mac and iPhone apps when they launch.

Full refund within 30 days, just email us. support@grainfocus.app

Questions

What does unlock include?

Grain Unlock is $19 once, plus tax where applicable. All future themes included. It removes the daily free-play limit. It also turns on the sleep timer, full screen, Background mode for an iPhone lock screen, and offline install. The focus timer and all six themes are free. A web Unlock will carry over to the Mac and iPhone apps when they launch.

Do I need an account?

No. A license key from Polar unlocks this browser. The key stays in local storage on this device.

Who handles payment?

Polar is the seller of record. Polar takes the payment and sends the license key. Grain never sees the card. The privacy page says what is stored and what is sent.

Will it keep playing if the phone locks?

With Grain Unlock, turn on Background mode, then press Play. The player renders ahead and keeps the session going on the lock screen, including a long timer. Without that, live audio stops when the browser is suspended.

Does this unlock the Mac and iPhone apps?

A web Unlock will carry over to the Mac and iPhone apps when they launch.

Can I get a refund?

Full refund within 30 days, just email us. support@grainfocus.app
