Look, this app is incredible. For years I used a dedicated lux meter and did all the math myself to convert to PPFD/DLI. Now, I can't even think of a feature I'd want that this app doesn't have. PPFD, DLI, color temp, lux, measurement hold, tilt detector, peak / average values, quick changes for DLI hours, oh and the values are correct too. Never before have I been so pleased with a piece of software! I'd pay for this app for sure, so long as it was a one time cost and not a subscription.

Great concept, quick response from support. I had an issue with a tip not dismissing and they got back to me the next day from the other side of the planet. The light readings are pretty far out from my actual meter, but hopefully they can fine tune it for better accuracy. Be sure to look through the extras on the site, they have a great little start of a plant database with light info for various species - looking forward to this being integrated fully into the app in time. Well done, devs!

Hi Samantha,
Thank you very much for your insightful review! We're happy to hear that you like our app :) If you have an actual meter and want both devices to read the same you can simply calibrate according to that. We have a guide showing how here: https://growlightmeter.com/guides/how-to-calibrate-photone/

Nice concept, but could use a lock for par. When I'm measuring I can't see my screen because the light is too bright. So I have to very quickly move the phone to where I can read it. By that time the phone isn't under the light so I can only guess at the par reading (it starts dropping as soon as it's moved from the light). On my Samsung Galaxy s8+ it appears to be reading very low.

Hi John,
Thank you for your feedback! I understand and what you are describing is our already existing "hold mode" feature. You can enable it by touching and holding the lower third of the screen to freeze the reading. Is there something else that we could do to deserve a better rating from you?
Best regards,
Dominik and the Photone Team
