| 2024-12-09 |  | | Using this for carnivorous plants. Im not expdcting the app to be very accurate, but it seems accurate enough! pretty impressive... All we need now is to be able to see Red, green and blue light spectrum amounts. |
| 2024-11-27 |  | | Very impressive. An app that delivers DLI which is ultimately the number an indoor grower should be looking for. Took my DLI chart from a grow light and was able to calibrate the app. Now I'm able to measure and adjust my other lights for optimal height/growth. Game changer. |
| 2024-11-26 |  | | On Samsung Galaxy s24 Ultra. After going into the settings and changing the diffuser setting to accessory, this app works very well with the light Ray diffuser accessory. This is an extremely useful app for measuring lighting. Thank you for giving me helpful advice. |
| 2024-11-05 |  | | This is a Really Great App for the home grower to dial in light intensityđź‘Ť This app only gets better as time goes on! âś… |
| 2024-10-23 |  | | seems to work very well. gives me a much better idea of what distance my lights are from my plants. |
| 2024-10-16 |  | | no back button Edit: Angela told me how to get the Android home buttons to work. It's glitchy, but works after a few tries. |
| 2024-10-03 |  | | my lights manual said at 18", I should read 657ppfd. Using a little piece of printer paper as a diffuser on my pixel 6a, the app read 648-657. damn good app! |
| 2024-09-29 |  | | A very useful app . Takes some of the guesswork out of cultivation. I think my seedlings are considerably less stressed at the correct DLI . |
| 2024-09-28 |  | | App shows absudly incorrect values on a bright light. Even when using with a paper diffuser, does not show realistic values. Not recommended, sorry. |
| 2024-09-24 |  | | You did something to mess up this app because my readings were dialed in to the 1s place, now all I get is measurements in increments of 10s nowhere near close to what they should be. Same exact phone. Have calibrated many times. |
