LUX Meter vs Candela

LUX Meter is a private light meter for quick, practical illuminance checks with your iPhone camera. Measure ambient light in lux or foot-candles, compare rooms and work areas, check desk lighting, find brighter spots for plants, and see whether a space is too dim, comfortable, or bright enough for detailed tasks. Pick a target for your task — reading, office, kitchen, plants and more — and get instant "too dim / good / too bright" feedback as you move the phone. Simple and trustworthy: no account, no ads, no tracking, no photo storage. Features: - Lux and foot-candle readings - Lighting target presets with live in-range feedback - Live brightness scale with plain-language guidance - Hold mode to freeze a measurement - Session min, average and max - Calibration against one trusted lux value - Practical guide with common light levels - Paper-diffuser guidance for incident light - Private on-device camera metering Important: LUX Meter estimates illuminance from camera exposure. Great for quick checks, comparisons, and plant or room-light decisions. For regulated, safety-critical, or professional compliance measurements, use a certified lux meter.

Candela turns the camera into a genuinely useful light meter. Point your iPhone and read the light around you — live illuminance in lux or foot-candles, exposure value (EV), and color temperature in Kelvin — on one beautiful instrument with a camera-iris dial that opens and closes with the light. One meter, three jobs: PHOTO / FILM • Live EV at ISO 100, plus a full exposure-triangle solver — lock any two of ISO, aperture, and shutter and Candela computes the third. • Color temperature readout for white balance. • Perfect for film shooters, manual photographers, and anyone learning exposure. PLANT • Convert measured light into PPFD and a projected Daily Light Integral (DLI) for the hours your plant gets light. • Instantly see whether a windowsill is deep shade, low, medium, bright-indirect, or direct sun — with example plants for each level. • Stop guessing why your monstera is leggy. ROOM / WELLBEING • Compare a spot against recommended light levels for reading, kitchen work, an office desk, and more. • A clear verdict — too dim, comfortable, or bright — plus a color-temperature note for evening, sleep-friendly lighting. Built for trust: • Calibrate to any reference in one tap so your readings match a meter you trust. • Lux or foot-candles, your choice. • Save a "spot" to remember a reading, with a tidy history. • A built-in Guide explains plant light needs, room standards, and a photographer's EV chart. Private by design: • Everything runs on your device. Camera frames are analyzed live and are never saved, photographed, or sent anywhere. • No account. No tracking. No ads. Data Not Collected. A note on accuracy: a phone camera is a reflected/scene light meter, so readings are a well-calibrated estimate rather than a laboratory instrument. For incident-style readings, meter off a neutral gray card. Calibration lets you dial Candela in to a reference.
