■ Your Camera, Reimagined as a Sci-Fi Movie Scope ■ 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 — visuals you'd only see in movies, now on your phone with no special gear. ■ Key Features ■ ● 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 — a deliberate nod to subject privacy. ● Lock-On Animation (Red Vector) Every 20 seconds, a randomly selected target gets a dramatic red lock-on animation — the green frame turns red and zooms in to capture it. This layers extra immersion on top of the standard HUD. ● Fully On-Device Processing All camera frames and detection data stay on your iPhone. Nothing is uploaded, transmitted, or stored externally. Privacy by design. ● Portrait & Landscape Support The HUD adapts automatically to portrait and landscape orientation, letting you frame shots however you like. ■ Requirements ■ iPhone (iOS 16.0 or later) / iPad (iPadOS 16.0 or later) ■ Technical Notes ■ 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.

Plume is a Dreamcast emulator for iPhone, iPad, and Mac. A polished library, deep graphics options, and controls for handheld play and couch co-op. Add games through the Files app, AirDrop, or the Share sheet. Supported formats include GDI, CDI, CHD, CUE, BIN, ZIP, 7Z, and ELF. Retail BIOS files are optional. Turn on Fast Boot to skip the splash, or add dc_boot.bin and dc_flash.bin from hardware you own for the full boot sequence. LIBRARY Your collection lives in one place with cover art, metadata, favorites, and play time. Every menu can show as Tiles or a List. After you run a game, Plume grades how it performs on your device (Excellent, Good, Playable, and more) so you know what to expect before you boot. Add any game to your Home Screen. CONTROLS Use fully customizable on-screen controls, or pair a Bluetooth gamepad in iOS Settings and remap every button in Plume. Dreamcast has four controller ports, and each port can hold a standard controller, arcade stick, twin stick, racing controller, fishing controller, light gun, maracas, train, rhythm or dance controller, keyboard, or mouse, each with its own touch layout. Touch controls fill port 1 when nothing else is connected. Rumble and haptics are built in. CONSOLE MODE Mirror your screen to a TV over AirPlay or HDMI. In Console mode the game renders on the big screen while your iPhone stays the controller. GRAPHICS AND PERFORMANCE Tune internal resolution, aspect ratio, CRT shaders, texture filtering, HDR, and upscaling. MetalFX upscaling and FSR 3 frame generation are available on supported devices. HD texture packs, neural upscale models, and Upscale Studio help older games look sharper. A live HUD shows FPS, frame time, CPU, RAM, and more. SAVE STATES AND VMU Save and load states from the in-game menu. Slots appear on library covers for quick resume. Per-game VMU files keep memory cards where they belong. CHEATS Add cheat codes by hand or import them for each game. RETROACHIEVEMENTS Sign in to RetroAchievements and earn badges while you play. Hardcore mode disables save states for a classic challenge. EXTRACT Hold a game in the library to extract its music, videos, and pictures from your own disc. CAPTURE AND SHARE Take screenshots and record gameplay in-game. Save them to Documents or Photos, or attach a capture to a save-state slot as a visual bookmark. SOUND AND STYLE Menu music from downloadable tracks, your own imports, or songs from your Apple Music library. Themes give you control over colors, fonts, corners, and accessibility, including Bold Text and Button Shapes when iOS has them on. REQUIREMENTS Plume runs on iPhone and iPad with iOS 17 or later, and on Mac computers with Apple silicon running macOS 14 or later. Your device may warm up during play, and heavy 3D games may not reach full speed on older devices. LEGAL Plume does not include commercial games or a retail BIOS. You are responsible for content you import. Only use game files and firmware you legally own. Dreamcast is a trademark of SEGA. Plume is not affiliated with or endorsed by SEGA.
