Ratings and reviews

The app has no benefit it can't measure the brightness of laptops and monitors.

Does not work properly on my OnePlus 13 does however work on my Galaxy S9. Probably an issue with what camera it's trying to use for its readings.

Initially, this app was unavailable for my phone. I emailed the developer who responded immediately and looked in to the issue. The app was made available for my phone within a few days, and after installing I found it highly useful and accurate - the readings on test images returned results very similar to those published in reviews using professional equipment. So 5 stars for the app and 10 stars for the support from the developer. A rare and precious thing.
