--- Know your focal length. Every shot. LiveMM displays your real-time 35mm equivalent focal length and angle of view directly on the viewfinder — so you always know exactly what you're shooting. Whether you're a film photographer trying to match a composition on your phone, or someone who wants to develop a sharper eye for perspective, LiveMM speaks the language of real cameras. --- REAL-TIME FOCAL LENGTH OVERLAY As you zoom in or out, LiveMM instantly shows the 35mm equivalent focal length (e.g. 26mm) and angle of view (e.g. 77°) on screen. No lag. No guessing. HARDWARE-ACCURATE READINGS LiveMM reads the field of view directly from your iPhone's physical camera hardware using AVFoundation. The focal length you see is calculated from the actual optics of your device — not a rough estimate. LENS PRESET BUTTONS Instantly switch between your phone's physical lenses — 0.5×, 1×, 2×, and 3× — with a single tap. LiveMM automatically detects which lenses your device has at startup, so it works correctly on any iPhone without a device database. PINCH TO ZOOM Use standard pinch-to-zoom gestures for continuous zoom between lens presets. The overlay updates in real time throughout the entire zoom range, including digital zoom. PHOTO CAPTURE WITH EXIF DATA Capture photos directly in the app. The 35mm equivalent focal length is written into the photo's EXIF metadata, so your camera roll tells the full story of every shot. --- PERFECT FOR · Film and mirrorless camera photographers shooting with an iPhone · Photography students learning to see in focal lengths · Anyone who wants to understand what their phone's lenses actually see REQUIREMENTS · iPhone 12 or later · iOS 16.0 or later · Physical device required (camera features are not available in Simulator) ---
