Light measurement apps

[Scottylikesbud]

Hello has anyone tried the app called korona. It’s supposed to measure ppfd and lux was wondering if it’s reliable?

I tried a couple different ones, my phone sucks, the light sensor caps out at like 36,800 lux or something around there so it won't measure high enough light levels to be useful for flower.

Musta been the issue with my phone ...it crapped out too so couldn't compare an app to.my PAR meter

Does this seem right? The sun is setting on the iPhone xr

I haven't tried APP, I have been using a special device, I think it will be more accurate
