Missing monster plant in the plants' category would like to know where the Montana lands on light spectrum. Also feel like tomato plants and other fruits and veggies should be there. Also have checked fully but a moisture recommendation for the plans would be a nice bodice for thoes who have money and time to make conditions for plants ideal. Have a few green houses I need to get in check and having it all on one app would be amazing

We rescued a human and chick succulent from grocery outlet. Must-have been "in the dark" of the store for quite a while. Using a medium-sized desk lamp he was able to ascertain that it had just enough warmth and light output when adjusted close to it to keep it healthy and alive at 20,000 lux although outdoors would be 25,000. Like radiation poisoning, but the opposite, our new responsibility is likely to be in for a hellish time, but we saved the roots and inner growth center. Going to be awhile.

So glad this was available, started a hydroponic grow and money was tight... so thankful to Lux for the availability of a light meter right in my phone.

Lopped off three stars because I couldn't figure out the meter is looking at. Blocking the facing camera does not lower the LUX value. Blocking the forward camera does not lower the LUX value. The LUX value changes by moving the phone with all cameras covered on a Motorola 5G.

Let me get this straight - this app comes with two separate sets of functionality. The first set is available for all to use. The second is behind a paywall with zero way to test the functionalities or even preview the design of the tools before payment. That's not the mark of a good business model that is respectful of the individual needs and preferences of those whom you're asking to invest in your product. Automatic out. Now to test the contenders before choosing one worth investing in.
★☆☆☆☆Breck Fry· Sep 24, 2024
Is there any way to change the light sensor to the front camera? I don't really need to know how much light is on my face.
★☆☆☆☆A Google user· May 30, 2026
Hey, your photometer.pro domain expired, and now when the app is opened, all we see is a full screen ad to buy/renew the domain with no way to get to the app home screen. There's a back arrow on the banner across the top of the ad page, but all it does is reload the ad. Better renew quick, lots of registrars charge high fees to get a domain back if you let registration lapse for more than a couple of days.
