Mahindra, the app is completely free to try out for a few weeks, no signup - just tap close on the paywall. It is in this way so that you can try out before you buy. Thanks for your understanding!

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.

Nits Meter uses your phone's front camera to measure screen brightness of any laptop or monitor. Just point your phone at a laptop or monitor display to measure it. Hope that helps and let me know if there are any problems. apps@contechity.com. Thank you!
