Paint matching needs work

The scanner seems to be accurate but the way the paint matching works is a daft. You have to know the paint brand and can only look at one paint brand at a time. Also, the match is fairly coarse- only 1 - 3 out of three.
I was trying to match the paint in my house but several brands had equal level of matches in the app.
I solved the problem by putting a screen shot of the LAB values from the app into ChatGPT. It searched all UK paints and its top match was correct.
The paint matching in the app should:

1) Give a confidence level as a percentage

2) Search for matches across all brands in the region you have chosen

Response from developer

Thank you for the great feedback!

My Fingers Hurt

The app and sensor work fine, but the inability to save and export bulk data as a .csv has opened my eyes to the wrist pain of heavy numpad use. Plus, it's kinda annoying that the sensor crashes if you tab out of the app while it's collecting data.

Response from developer

You can export as a batch from the web dashboard. Please log into https://app.nixtoolkit.com Contact support if you are still unable, and we will help work it out with you.
