Real-time rim rendering — every beat drives the glow.
Every part of the light is yours to shape — color, motion, glow and thickness, live as you drag.
Pick a palette, or let Rimlight pull colors straight from the album art playing right now.
Let the light travel around the frame with the beat, or lock it in place for a calm, steady wash.
From a whisper of light behind the bezel to a full room-filling bloom — it's one slider.
A hairline rim or a wide gradient halo. Adjust per display, and Rimlight remembers.
Rimlight reads the track playing in Apple Music or Spotify and pulls the two dominant colors straight from its cover art — no screen recording needed.
Rimlight reads the current track straight from Apple Music and Spotify and shows it right in the app — cover artwork, title, artist and elapsed time, updating as the song moves.
The transport controls actually work: skip to the previous track, play or pause, jump to the next one, and drag the scrubber to seek anywhere in the song. None of it requires screen recording.
