About this launch

Grain is a web-based music player that generates ambient focus music live as it plays, so it never loops. The mood of the music follows the time of day, staying soft for long listening sessions. It offers a free 25-minute focus timer and includes six themes to choose from. The player works in any modern web browser on Mac, Windows, Android, Chromebook, and iPhone.
The free version includes 30 minutes of daily play and access to all six themes. Grain Unlock ($19 once) removes the daily play limit, adds longer focus timers (45, 60, 90 minutes) and a sleep timer, enables background playback on iPhone lock screens, and allows offline installation. No account is required—the license key stays in local storage on your device. Mac and iPhone apps are planned, and the unlock key will carry over to them.

Shopper questions
What does Grain Unlock include?
Grain Unlock ($19 once, plus tax) removes the daily 30-minute free-play limit and adds longer focus timers (45, 60, 90 minutes), a sleep timer, background playback for iPhone lock screens, and offline installation. All future themes are included. Mac and iPhone apps are planned, and your unlock key will carry over to them.
Do I need an account to use Grain?
No. A license key from Polar unlocks this browser. The key stays in local storage on your device, so no account is needed.
Will Grain keep playing when my phone locks?
With Grain Unlock, turn on Background mode and press Play. The player renders ahead and keeps the session going on the lock screen, including long timers. Without this, live audio stops when the browser is suspended.
Will my Grain Unlock key work on Mac and iPhone apps?
Mac and iPhone apps are planned. Your Grain Unlock key will carry over to them when they ship. Today it unlocks the web player in your browser.
Can I get a refund?
Yes, Grain offers a full refund within 30 days. Just email support@grainfocus.app.
