DisplayScale

DisplayScale is a utility app designed for UI/UX developers and designers to check screen metrics, verify accessibility compliance, and keep local logs of project layout specifications. The application runs completely offline with no network requirements or user account registration.

Key Features:
- Aspect Ratio Calculator: Input pixel dimensions (width and height) to instantly calculate the simplified ratio, decimal value, and match the result against standard desktop and mobile viewport presets.
- DPI/PPI Density Estimator: Enter screen width, height, and diagonal screen size in inches to estimate screen density (PPI), asset scale multiplier, and target Android density bucket (such as mdpi, xhdpi, or xxhdpi).
- Color Contrast Analyst: Input custom hex codes for text and background colors to evaluate contrast ratio scores. Confirm compliance standards (Pass or Fail status) against WCAG 2.1 AA and AAA rules for normal and large typography with a live canvas preview.
- UI Layout Checklist: Interactive checklist categorized by Interaction, Typography, Layout, and Accessibility. Follow standard guidelines to check your screen layouts, with progress saved automatically.
- Project Logger: Maintain an offline database of your project dimensions. Log screen width, height, custom padding guidelines, and notes, with the ability to add, edit, search, and delete entries.
