Terrible purple font

Just needed a 1 time check but I am not sure about the accuracy since it gave me a rating on my desktop monitor of 10 nits on a monitor which can go up to 350 nits. Why 350 possible nits if I am really only using 10 Nits? ***2nd point: The purple font/ text on the website is extremely hard to read. Use another color & get feedback from peers before finalizing the final color. ***Still I appreciate the effort.

Response from developer

Thanks for the detailed feedback! A reading of 10 nits does seem unusually low — did you measure a white area of the screen, and was the room dark or light? Most screens auto-adjust brightness and often output well below their maximum. If something seems off, I'd love to investigate further — reach out at apps@contechity.com. Regarding the purple font, I only use black and dark blue text on the website, so I'm not sure what you may be seeing there. Feel free to contact me at apps@contechity.com if you'd like. Thanks again!

annoying paywall

Worked pretty well for a while until I opened the app and it no longer allowed me to use the measurement feature for free. I’m now forced into a free 3-day trial, after which I’m charged $2 a month unless cancelled, or a one-time $10 purchase. It’s not the most ridiculous paywall I’ve ever seen, but it sure is frustrating that the basic functionality of the app has been stripped away.

Response from developer

Hi, I appreciate you taking the time to leave a review. Nits Meter is free to try for a few weeks, and then yes, if you like it, a one-time purchase or small subscription is needed to keep going. I am working on making this clearer. If the trial felt too short, I'd love to make it right — just drop me a line at apps@contechity.com and I can extend your test period. Sorry and thanks again!
