Way off!

Using a spider farmer g5000 grow light sitting at 24” above canopy pulling 200 watts at 40% in 4th week after seed popped soil surface. Leaves are praying but level with eye. This app says I’m at 70 ppfd. Wouldn’t suggest this app to nobody. Doesn’t even reach suggested ppfd sitting right under light at 100%. You use this and you’ll fry your plants crispy for sure.

Excellent light measure

Very easy to use and excellent light meter. It is also reasonably accurate and no big fluctuations when you hold your phone steadily in front or under the source as the case may be. Works for LED, incandescent, natural sun etc. No required diffuser attachments. No muss no fuss. Totally decent application!

We are grateful for your positive feedback! We are constantly working to improve our light meter, and your support is very important to us. Thank you for choosing our app!

Poor App Support

The App has no instructions or documentation to show how to use the meter. Also super limited capabilities unless you buy the paid version. I will be deleting the app from my device.

Measures much lower values than a calibrated light meter

I tried to see if this could replace a calibrated light meter, but the answer is a definite NO. The measured values are 1/2 to 1/3 of what the light meter reads for a LED test source. At very high flux levels (~10 klux) the values are lower by a factor of 10.
