About
Your iPhone torch can do far more than on and off. Lumen drives its brightness smoothly — like an instrument.
MUSIC
• Music Sync — Lumen listens through the microphone and flashes in time with whatever is playing around you: a speaker, a party, a concert. Analysis happens on the device, and nothing is ever recorded. In a quiet room the light simply stays off.
LIGHT MODES
• Candle — light it with a match or a lighter, watch it flicker, then blow at your phone to put it out. Really blow: the microphone hears you.
• Strobe — a party strobe; tap along to the beat and it locks the tempo.
• Breathe — guided breathing (Calm, Coherence, Box, 4-7-8). The light leads while gentle haptic taps tell you when to inhale and exhale.
• Heartbeat — a slow lub-dub pulse.
TOOLS
• Morse & SOS — type a message and the light blinks it in real Morse code.
• Metronome — a visual click with accented downbeats.
• Intervals — workout rounds: green light to work, blue to rest.
• Beacon — a slow visibility flash for night rides and walks.
Every mode can drive the LED, fill the screen with color, and tap along with haptics.
PRIVATE BY DESIGN
No accounts, no ads, no tracking. Microphone audio is analyzed on the device in real time and is never recorded, stored, or sent anywhere.
SAFETY
Flashing is capped at 20 Hz, and Lumen shows a photosensitivity warning on first launch.

What's New in Lumen
1.1.1
August 22, 2026
• Lighting the candle is a show again. Strike a match or flip the lighter open and watch it come down to the wick — the animation used to play out past the bottom of the screen, where nobody could see it. • The candle looks like a real one: a charred wick that leans, a flame whose tip dissolves into its own glow, and wax that melts and glows around the flame. • The lighter is drawn in full — brushed case, hinged lid, windscreen and flint wheel. • The flame now goes out only when you press Blow out or actually blow at your phone. Tapping the candle no longer puts it out by accident.
