โ–  Your Camera, Reimagined as a Sci-Fi Movie Scope โ–  Lock2Cam overlays a real-time object detection HUD on your iPhone's camera feed, transforming everyday vision into a sci-fi / cyberpunk experience. A near-future scouter, a fighter jet's target view โ€” visuals you'd only see in movies, now on your phone with no special gear. โ–  Key Features โ–  โ— Real-time Object Detection HUD The app detects people and objects in your camera feed in real time, drawing them with neon green frames and rune-style labels that follow each target. The stylized labels add to the sci-fi atmosphere while keeping detected names visually obscured โ€” a deliberate nod to subject privacy. โ— Lock-On Animation (Red Vector) Every 20 seconds, a randomly selected target gets a dramatic red lock-on animation โ€” the green frame turns red and zooms in to capture it. This layers extra immersion on top of the standard HUD. โ— Fully On-Device Processing All camera frames and detection data stay on your iPhone. Nothing is uploaded, transmitted, or stored externally. Privacy by design. โ— Portrait & Landscape Support The HUD adapts automatically to portrait and landscape orientation, letting you frame shots however you like. โ–  Requirements โ–  iPhone (iOS 16.0 or later) / iPad (iPadOS 16.0 or later) โ–  Technical Notes โ–  Object detection runs entirely on-device using Apple's Vision framework with the official YOLOv3 sample model (Apple Sample Code License). No cloud services, no third-party SDKs, no analytics. Turn the everyday into sci-fi.
