## What is Design Checkers?

Design Checkers is a web browsing utility built for web developers and designers who need to test and preview web designs directly on their iPhone or iPad.

Enter any URL and view it through three different rendering engines:
- SFSafariViewController for native Safari experience
- External Safari for full browser testing
- Custom WKWebView for controlled environment testing

Features:
- Quick URL input with history
- Three viewing modes for comprehensive testing
- Native iOS rendering for accurate previews
- Test responsive design on actual devices
- Simple, developer-focused interface
- Fast switching between viewing modes
- Share and bookmark tested URLs

Perfect for:
- Web developers checking responsive layouts
- Designers reviewing web proposals
- QA testers verifying cross-browser rendering
- Anyone who needs to quickly preview a website

Why use Design Checkers?
Testing web designs on real devices is essential for quality assurance. Design Checkers makes it easy to quickly load any URL and see exactly how it renders in different iOS browsing contexts — without needing to open separate apps or configure complex testing environments.
