Libre Light Sensor

Thanks for such a great app. It does what it says and that's it! Simple and straightforward. I have two suggestions. As I am using this to check the light from my light therapy box, I'm putting it by my eye, so I can't see the reading on the phone screen. It would be great if I could press a button to save the reading at that moment, so I can pull the phone away from my eye and see the reading. Then press the button again to go back to live measurements. And a button to exit the app would be good too.

I tried another App and it basically did NOTHING but forcing you to pay for a subscription. So I found this one and I am blown away. This works great. You point it a the light source and it tells you how much lux your plants are getting. Now I know why they aren’t doing as good as they should. I’m like a 71 year old kid running around pointing my phone at every thing. I would gladly pay for this; not a subscription, but a one time fee of $5-$8.

All other lux meters I installed and uninstalled, with their many positive reviews, started free, then sometimes it was very obviously inaccurate. Eventually it would boil down to “it would be accurate if you buy this or that and add it on top … now you could make one yourself from newspaper, but it will not be as accurate”!! I used this to measure how much light will hit my eyes when I read a book, vs read from browser on monitor, vs read dark theme article on monitor. It gave me perfect comparison of each for free. Reduce monitor brightness and contrast, all show how much difference they make.
