Photone here with a uni-t Meter. Photone has a calibration setting. With the uni-t it was only off 6% when compared to readings from an apogee (I rent for calibration). When I used the light sensor on my android it wouldn't even read past 650umol/s full stop.
Can confirm it is very inaccurate with the standard light sensor.
we weren't discussing the app at all until I posted the link to the calculator. Troll elsewhere.
