## What is ScreenTwin?

ScreenTwin turns any screenshot into an interactive design inspection canvas. Measure spacing, sample colors, read typography, and export developer-ready specs — without leaving your phone.

MEASURE ANYTHING
• Distance, width and height between any two points
• Horizontal and vertical guides that snap to detected edges
• Zoom to 20× for sub-pixel work
• Smart snapping to edges, centers, baselines and equal spacing
• A floating ruler you can drag and rotate, with a live angle readout
• Units in px, pt, dp, mm, cm or inches — or define your own

INSPECT EVERY DETAIL
• Long-press anywhere for a magnified eyedropper
• Every notation: HEX, RGB, HSL, HSB, CMYK, LAB, LCH, OKLab, OKLCH
• Copy-ready Flutter, SwiftUI, UIColor, Compose and CSS literals
• WCAG contrast ratios against white and black
• Color harmonies and 50–900 tonal ramps generated in OKLCH
• On-device OCR estimates font size, weight and line height

ANALYZE THE LAYOUT
• Detects buttons, cards, icons, avatars, navigation bars, tab bars, text fields and dividers
• Every detection shows its confidence and the rule behind it
• Automatic spacing analysis: gaps, padding, margins and element sizes
• A 0–100 score for how closely a design follows an 8-point grid
• The spacing scale your screen actually uses

EXPORT DEVELOPER-READY SPECS
• Annotated PNG and machine-readable JSON
• PDF spec sheets for handoff
• Paste-ready SwiftUI and Flutter code
• Design tokens as a Flutter theme, SwiftUI, CSS variables, JSON or W3C Design Tokens

REVIEW TOGETHER
• Comment pins, arrows, highlights, rectangles and freehand marks
• Status and resolve tracking on every note
• Compare two versions with slider, split, overlay or difference modes
