Auto measure
Detects the boxes on screen and derives every gap, padding and size without you drawing a thing.
Real units
Reads in points, pixels or your own unit, using the capture scale worked out from the screenshot itself.
Colours & type
Sample any colour, recover font sizes and weights, and collect them into a palette.
Design tokens
Export what you measured as W3C design tokens, CSS or Swift — ready to paste into a codebase.
Compare
Put two screenshots side by side and see what moved, what changed colour and what disappeared.
Stays on device
Screenshots are never uploaded. Text recognition runs on device, and projects are stored locally.
Private by construction. ScreenTwin has no image upload path at all — your screenshots are read, measured and stored entirely on your device. See the privacy policy for the detail.
