About this app

Lumen is a camera that doesn't hide its values.

EV, ISO, shutter, focus and white balance are on screen as numbers, always —
and one tap locks all of them. Recompose without your exposure drifting.

■ Precise colour — free
Temperature in Kelvin and green↔magenta tint, together, on one two-axis pad.
A precision the competition doesn't offer. In Lumen it's free.

■ It won't die at the decisive moment
Survives incoming calls and thermal throttling.
Shoots from the volume button. Launches straight from the Lock Screen.
All of that is free too.

■ Free, forever
Auto shooting · EV compensation · tap to focus · two-axis white balance ·
lens switching · histogram · grid · level · burst · volume shutter ·
Lock Screen launch · photo library

■ Lumen Pro
· Manual mode — ISO, shutter, focus
· One-tap lock — every value at once
· RAW · DNG · RAW+JPEG
· Video — 4K, interval, time-lapse
· All 22 filters

■ Privacy
Lumen contains no networking code at all.
No servers, no accounts, no analytics, no ads, no tracking.
Nothing you shoot or configure ever leaves your phone.

——
Every Pro feature is free for the first 6 months after install.
After that, Lumen Pro is an auto-renewing subscription or a one-time lifetime purchase.
Cancel anytime.
