★★★★★
Actually works. Actually accurate. But order the 27 dollar diffuser accessory. Sounds silly, but it's legitimate and literally causes my Samsung A52 mid-range phone to consistently give me PPFD and DLI readings that confirm my LEDs manufacturers light tests to be accurate! This is the only legitimate par meter app that is not a silly app compared to a 600 dollar apogee part meter. This is not as proficient as apogee obviously but even apogee instruments Founder vouches for the efficiency!
★★★★★
This app has been fantastic, I have the diffuser accessory now, and it made it a lot more stable. I have been using paper, and it was reading quite a bit lower than it actually was, and I always thought I was having to run my plants with low light and I felt bad always trying to push them thinking I was running low. Now, with the accessory, it seems to be much better. I had to raise my lights and dim one of them, and after a couple of weeks, everything is great.
★★☆☆☆
Update ruined this app, lower from the light I go brighter it reads and vice versa going up gets dimmer sorry guys
★★☆☆☆
Used this app for years worked great now I need a diffuser yet never did before nothing has changed same light same grow space sounds like cash grab
★★☆☆☆
Need a separate device now. Was the only reliable source for a long time. So long old friend.
