Well app

I like the idea of having incident and reflected light meter in one app. It is somehow accurate, but compensation is required. In my case the reading of the app is one step lower then the readings on my 35mm TTL Minolta x-700 camera. The solution is just to dial one step hire iso and the readings of the app would be correct. I did the test in a dim room pointing the reflected light meter at the window in sunny day. My camare readings for 100 iso were 1/125 at f2.8, the app shows the same reading on 200iso.

very good

Got the free app so I could measure the light and sun into our apartment block as the property speculators want to block it with a new hotel. Will get the paid app for my partner who likes photography if it works well. Seems to be good and not many permissions - like that a lot!!

Very good!

Super useful. May not be exactly accurate but it is very helpful for determining if something is getting as much light as you think it is compared to the rest of your space.
