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.

The minimum nits the screen should be is 250. my reading at max brightness is only 20. way off. so it gets one star.

Sorry and thanks a lot for reporting! Something is clearly not working as it should. Do you get any warnings from the app? Have you accidently applied an extreme and wrong calibration? Could you please send a screenshot of the app when you are using it, to me at apps@contechity.com? Thank you!

A popup nagging you to buy premium makes the basic function of the app unusable These free to download, but paid to use apps are very annoying. Just make the app paid from the store so you don't waste people's time

The app is free to test of for a few weeks. Simply tap "close" on the paywall. This is so that you have the option to test it out before buying. If you did not have enough time to test it out, please send me an email and I can prolong your test period. Thanks a lot!
