This is a well designed and modern looking metering app. Thank you for responding to my inquiry relating to the absence of ISO 64, and hope to see its addition soon. Update: 5/28/25 Huge thanks for the addition of ISO 64, Fantastic App!!

I've checked this light meter against my siconic L308, all readings are spot on aperture shutter speed and ISO. well, worth the small cost, I would highly recommend.
