Yes. I have Pocket Light Meter by Nuwaste Studios (most used). Lightmate is comparable. The app Lightme should be very good but I find it very confusing and grab to Pocket Light Meter 9 times out of 10.Point the iphone camera at something 18% grey (grass, tiles or asphalt) in the shade and consider the rest as sunny 16 (clouds entering, +1, sun brighter -1, etc).
Just use your lightmeter and app simultaniously at home fooling around and you’ll quickly learn when it needs adjustment and with what it is most reliable.
There’s so much more in a customers decision than ‘price’. I’d even think that ‘price’ isn’t even very high up there.
