Luxmo

Luxmo turns your iPhone into a fast, precise reflected-light meter for photographers. Point it at your scene and read a correct exposure instantly — aperture, shutter and ISO — on a calm, single screen with no clutter. Built for film and analog shooters who want a dependable meter in their pocket, Luxmo is fully offline. No accounts, no ads, no tracking. Nothing you measure ever leaves your device. — WHAT MAKES LUXMO DIFFERENT — • Instant, real-time reflected-light readings on one clean screen — no menus to dig through • Solves aperture, shutter, and ISO with priority modes, using real photographic units (f-stops, shutter speeds, ISO) plus EV, lux, and foot-candles • Values snap to standard full, ½, or ⅓ stops, just like a real meter — pick what's set on your camera and your film speed, and it solves the rest • Hold a reading whenever you need to lock in a value • Private by design — fully offline, on-device only, no accounts, no ads, no tracking — PRICING — Luxmo is free, with live reflected metering, aperture priority, and EV/lux/foot-candle readouts included. Luxmo Pro is a one-time purchase — no subscription, pay once, yours forever — that adds spot metering (tap to meter just one part of the scene), shutter and ISO priority modes, exposure compensation in ½ / ⅓ stop increments, and a saved readings log with notes and CSV export. Luxmo is a reflected-light meter and is not affiliated with any camera or film manufacturer. — FEEDBACK — Made by a small indie team.
