Great app!

Great for science projects really helped me, I got a %98. Definitely worth getting!

Fantastic

Fantastic app top marks

Great simple app. A few recommendations

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.

Camera

The app is working great and it is free! The only problem is that there was no option given for the camera to be in use only when using app. Otherwise, I love its simplicity and that there is a chart for different lux levels in different scenarios.

Perfect

Best app Iโ€™ve tried to just measure Lux levels.

11.23.25 Todayโ€™s itโ€™s not loading. Hope itโ€™s temporary. Seems like an iOS update messed it up โ˜น๏ธ
