PixelStick is a tool for measuring distances, angles, and colors on the screen. PhotoShop has distance, angle and color tools but they only work in PhotoShop. PixelStick works in any app and anywhere on screen anytime and costs a hundred times less.
Most of what PixelStick does is obvious. Drag the endpoints to change the measurement. Click the locks to constrain the movement. Launch it, play around, no more limitations to just one app in measuring distance, angle, and color.
