No test mode. – Nix Pro Color Sensor Review

Don't bother downloading, unless you already own the $249 (USD) accessory sensor. The app won't work without it. It would be nice, if you could check out how it works without first dropping that much $$$$. Unless the accessory device price point can be brought down under $50, I guess I'll just have to continue taking pictures of the colors, opening them in Photoshop and using the color picker there or holding a Pantone color-selector book next to my target color.
