This Demo version of ArgyllPRO ColorMeter has some reduced functionality.
The ArgyllPRO ColorMeter is an innovative Android application designed for both Tablets and Phones, that lets you use your USB connected color measurement instruments on the go, as well as save them for use later. The popular color instruments supported can be used for a wide range of common light and color measurement tasks, so ColorMeter provides a great deal of flexibility and configurability, allowing you to customize it to the task at hand and switch tasks rapidly.
Of interest to Designers, Graphic Artists, Photographers, Architectural and Theater Lighting Designers, Printing Professionals, Colorists, Film professionals and TV & Digital Cinema calibrators.
This free demonstration version of ArgyllPRO ColorMeter is fully functional, except that it shows the closest of one of the 8 pre-determined Demo instrument readings instead of the true measurement values from your instrument, times out after 3 Weeks, and also encourages you to return a short survey about your experience.
If you think the software will be useful to you, and you have confirmed that your color measurement instrument functions with this demo version on your Android device, then you can purchase the fully functional version of ArgyllPRO ColorMeter from Google Play.
