Appkiro Mobile Simulator is a developer-focused Chrome extension designed for responsive web testing, viewport emulation, and pixel-perfect design inspection directly in your browser. Test how any website looks and interacts across mobile phones, tablets, foldables, and desktop viewports without physical devices or external testing labs. KEY CAPABILITIES • Accurate Viewport Emulation Simulate mobile and tablet browsing environments with authentic screen resolutions, device pixel ratios (DPR), user-agent strings, and native touch event simulation. • Multi-Device Side-by-Side Testing Open and compare multiple device viewports simultaneously in a single browser tab. Synchronize scrolling, clicks, and navigation to verify responsive breakpoints in real time. • Mockup Frames & Presentation Display websites inside realistic device frames with optional OS status bars and address bars. Clean presentation layouts make client demos and design reviews effortless. • Flexible Screenshot & Video Capture Capture viewports with frames, clean website-only views, or complete full-page scrolling screenshots. Record screen interactions with microphone audio and camera overlay for bug reporting. • Batch Testing Matrix Run responsive checks across multiple viewports in a single automated pass.
