Version 1.2 introduces PatternScope Pro — an optional one-time upgrade that turns a nearby iPhone or iPad into a measurement microphone for your home theater. Everything the app already did stays free, unchanged, and fully included. NEW: PATTERNSCOPE PRO (one-time purchase, $4.99) Using Apple's Continuity Camera & Microphone — no companion app to install: • Live Level Meter — relative input level with peak, noise-floor, and clipping indicators • Speaker Level Match — measure each speaker against a reference and get receiver trim suggestions • Room Response — sine-sweep measurement with a relative frequency-response graph • Subwoofer Integration — compare mains, sub, and combined output around your crossover • Relative Timing & Polarity — arrival-time and polarity comparison across speakers • Automatic A/V Sync — estimate your system's audio/video offset with the phone's camera and microphone • Guided Complete Audio Setup workflow, saved measurement sessions, and local-network report export (QR code) All measurement is processed on your Apple TV. No account, no subscription, no cloud — audio and video are never recorded or uploaded, and reports leave the device only if you export them over your own Wi-Fi. Measurements are relative, consumer-level diagnostics: results reflect the phone's position and your room. Requires a Continuity-capable Apple TV 4K and a nearby compatible iPhone or iPad.

Version 1.1 adds a new Geometry & Convergence category plus more reference and calibration patterns — and, as always, every pattern explains what it is and what to look for. NEW: GEOMETRY & CONVERGENCE • Crosshatch Grid — check screen geometry and linearity; spot pincushion or barrel bowing • Circle Grid and Single Circle — confirm circles stay perfectly round (correct aspect ratio, no stretching) • Starburst — judge center sharpness and convergence • RGB Convergence — reveal red/green/blue misalignment, especially on projectors NEW REFERENCE PATTERNS • Resolution Wedge — find the limit of your display's resolution • Multiburst — check fine-detail contrast and high-frequency rolloff NEW CALIBRATION PATTERNS • Gamma Estimation Chart — read your display's gamma by eye • Clipping Targets — set black level and contrast with near-black and near-white targets • Color Step Wedges — check grayscale and color tracking Still no account, no network, and no tracking — nothing ever leaves your Apple TV.
