Luxdeck turns your iPhone camera into a light meter. Point it at a lamp, a window, or a grow light and read four things at once: illuminance in lux (or foot-candles), PPFD and DLI for plants, and the color temperature of the light in kelvin. Most light meter apps make you buy or clip on a diffuser dome before the numbers mean anything. Luxdeck reads straight from the camera, so you can pull it out and measure whenever a question comes up: is this corner bright enough for the fern, how warm is this bulb, is the desk lit well enough to work. WHAT IT MEASURES Lux and foot-candles for everyday lighting. PPFD, the light plants actually use for photosynthesis. DLI, the total light a spot receives over a day. Color temperature in kelvin, from warm tungsten to cool daylight, with a warm-to-cool scale so you can read it at a glance. BUILT TO BE HONEST Every reading carries a small badge that tells you how confident the measurement is and whether the app has been tuned for your specific phone. No hidden fudging, no pretending a phone camera is a lab sensor. WORKS ANYWHERE, KEEPS TO ITSELF Everything runs on the phone. There is no account to create, no network call, and no data leaves the device. The camera is used only to read light in the moment; frames are never stored or sent. FOR GROWERS AND EVERYONE ELSE If you keep plants, Luxdeck reads PPFD and DLI so you can match a spot to what a plant needs. If you shoot photos, set up a room, or just want to know how bright and how warm a light is, the same numbers are there without any gardening jargon in the way. Free to use. A Premium upgrade unlocks unlimited saved history and CSV export for people who log readings over time. Terms of Use (EULA): https://www.luxdeckapp.com/terms

Verdict
The clearest difference is update cadence: Luxdeck at every 3 weeks against Rechnung Scanner's every 4 months. Luxdeck also leads on iOS requirement (16.0 vs 18.1). On price, ads, in-app purchases and device support there is nothing between them.
