CamCheck helps you inspect an iPhone camera system before buying, selling, repairing, or accepting a used device. Use the app to check for possible camera dust spots, focus sharpness issues, shake stability, and differences between available camera lenses. CamCheck is designed for marketplace buyers, resellers, repair shops, and anyone who wants a quick camera inspection workflow. CAMERA DUST TEST Point the camera at a white wall, white paper, or another evenly lit bright surface. CamCheck analyzes the captured image and highlights possible dark dust marks or lens/sensor artifacts. FOCUS SHARPNESS TEST Use the built-in focus test pattern to check camera sharpness. Display or share the pattern on another screen, capture it with the tested iPhone camera, and review the focus score. FRONT & BACK CAMERA TESTING Inspect both rear and front cameras. For supported devices, compare available rear camera lenses such as Wide, Ultra Wide, and Telephoto. STABILIZATION & SHAKE TEST Hold the device still and run a motion-based stability test. CamCheck uses device motion sensors to estimate shake stability during inspection. CAMERA REPORTS Save inspection results, compare camera captures, review scores, and export a clean PDF report for buyers, sellers, repair shops, or personal records. USEFUL FOR: • Used iPhone buyers • Marketplace inspections • Phone resellers • Repair shops • Refurbished device checks • Personal camera health checks PREMIUM FEATURES: • Unlimited camera inspections • Front and back camera diagnostics • Multi-lens comparison • PDF reports • Focus chart testing • Saved inspection history Important: CamCheck is an inspection aid.
