KaliTrue vs SpotRange

The KaliTrue app is designed to help people calibrate their displays to most accurately reflect colors. A user manually adjusts their display to show a white screen as "pure white", and KaliTrue allows them to measure the screen to see if it's indeed showing pure white, and if not the app tells them what needs to be adjusted to correct it. The app does not automatically calibrate your display... there are already apps for this but they require specialized hardware. This app is essentially a measuring device that assists you in manually calibrating your displays by showing you what needs to be adjusted. The project home page is at KaliTrue.app
