### 5/5 — 便利

*2026-05-19*

仕事がら明るさを手軽に測れるのは助かります。キャリブレーション用の光源が無いけど、相対的に測定して利用してます

**Developer response:** 温かいレビューと5つ星をいただき、本当にありがとうございます！Nits Meterがお仕事に役立っているとのこと、大変嬉しく思います。相対的な測定値として活用されているアプローチは賢く、ディスプレイ間の意味のある比較を得るための完全に有効な方法です。経験を共有していただくお時間を割いてくださり、改めてありがとうございます！

### 2/5 — Terrible purple font

*2026-04-19*

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.

**Developer response:** 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!

### 3/5 — annoying paywall

*2026-04-07*

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.

**Developer response:** 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!

### 5/5 — Helped with science fair fr 🥹✌️

*2026-01-22*

Amazing, helped with a light project for school

**Developer response:** Great to hear! Thanks a lot for your support!
