Donβt let accessibility compliance halt your deployment. With Appleβs enforcement of Accessibility Nutrition Labels and global regulatory pressures like the European Accessibility Act (EAA), submitting inaccurate accessibility declarations can stall your app in App Review or risk serious compliance rejections. Accessibility Audit provides a seamless, offline-first auditing engine that checks your mobile user interfaces in seconds. Simply load or drop a screenshot into the workspace to run an on-device, localized compliance scan that helps you confidently fill out your metadata sheets. Core Compliance Pillars: VoiceOver Semantic Validation: Automatically detects missing interactive text labels and analyzes structural focus routes. The engine visualizes the logical path a screen-reader user would navigate, warning you if layout hierarchies jump or skip critical elements. WCAG 2.2 Contrast Math Engine: Computes pixel-precise relative luminance ratios across light and dark interfaces. Instantly maps text elements and background layers to verify conformity with absolute standard requirements (4.5:1 or 3:1 targets). Tap Target Physical Auditing: Measures the physical boundaries of touch elements. Identifies interactive regions failing the baseline requirement (44x44pt or 48x48pt) and highlights narrow spacing boundaries to mitigate accidental mis-taps. Privacy-First Processing: Your visual layout components and technical designs never leave your local device. Every calculations engine and programmatic vision layer runs locally, ensuring proprietary mockups remain confidential. Direct Compliance Mapping Built For App Store Connect: Generate immediate, actionable insights specifically formatted to answer the official App Store declaration sections: Interaction Methods: Clear visibility scores for VoiceOver and Voice Control frameworks. Visual Accessibility: Mathematical validation patterns across Sufficient Contrast metrics. Interface Flexibility: Immediate confirmation that element clusters safely scale and hold spatial integrity. Eliminate the guesswork of self-reporting. Download today to secure an uncompromised, accessible user experience for everyone while accelerating your release cycle. Prepare for Accessibility Nutrition Labels.
