Lueur

Voice notes you can see and feel

Lueur — pronounced “loo-ER” — means a faint glow.

It is the small light that appears in the dark, like an idea that suddenly comes to mind.

Lueur is a fast voice note app for thoughts, ideas, and reminders that might disappear if you wait too long.

Tap to record. Speak your thought. Tap again to save it.

A living glow.

During recording, Lueur turns your voice into a living glow, built in real time from the intensity, rhythm, and tone of your voice — unique to every person and every thought.

The animation reacts in real time to your speech: softer when you whisper, brighter when your voice rises, calmer when you pause.

Haptic feedback follows the same voice energy, so you don’t just see the recording — you feel it in your hand.

Private by design.
