"What I like about this app is that they allow you to more accurate readings based on your light type. I grow under red/blue LED which can give a totally different reading vs natural sunlight, incandescent, or even white LED"

"Great app to check the grow lights PPFD and the DLI for increasing yields. My wife didn`t renew my prescription because she thought it was a scam lol anyway I`ll renew it soon enough because it`s a great tool to have in a any growers arsenal. And i use a Samsung S21 Ultra."

"Easily off by 100% and requires a proper sensor to calibrate so this isn`t your alternative to investing in hardware (which typically has its own app.) I`ll stick with ``PPFD meter for now``. Dev: since you have people doing calibrations, why not store the calibration per device model and make that information available to users with the same hardware so they don`t need to calibrate? 😉 Update: After calibration using a UT383BT, results are still off 6-10% with my s22 Ultra."

"Off by about 30 to 50% on a Galaxy S10+ compared to an actual meter. Accurately reads calibration point after calibration, but is off by 10 to 15% when the light intensity changes. Works well for rough estimates but not as reliable as a meter."
