Enter your license key
On first launch Yellow's Out asks for the key from your Polar receipt email (it starts with YO-). Paste it and press Activate. The key is checked with Polar once, then the app works offline for up to 14 days at a time.
Start a session
Yellow's Out connects automatically when a compatible session is running — live or replay. The status dot in the title bar turns green.
