Seems ok. Simple to use. You can select different rooms but it will average across them all, which isn't helpful. Be great to start again with each room. Saving the average would be helpful too! App says 250lx is too high - my sitting room is 2000lx - lovely & bright.

I wish I could use reverse camera lens. hard to read light from my window if I can't see the phone.

Hi,
Sorry but the phone's light sensor is located only on the front side. Thanks!

Simple operation and useful guidance on acceptable light levels in different situations. Just right for me.
