iPhone

Read Duo’s hinge angle and display measurements, practise Split View gestures, and keep a saved note while folding. Live hinge data requires iPhone Duo. Duo Scope shows live hinge and layout measurements and provides instructions and practice activities for iPhone Duo. LIVE DEVICE READINGS See the hinge angle, app area, display scale and maximum refresh rate. Open or fold Duo to see the readings change. The device-readings page explains each value and shows recent hinge samples. Maximum refresh rate is a display capability, not measured FPS. PRACTISE DUO GESTURES Try separate activities for opening a Split View layout, returning an app to full screen, pairing and swapping apps, and dragging a note between panes. These practice layouts run inside Duo Scope; they do not control other apps. WRITE, DRAW AND PLAY VIDEO Write a note that remains saved while you fold Duo. Draw with your finger or a compatible Pencil, play the included video with native controls, and request a second app window where supported. FOLLOW FEATURE INSTRUCTIONS Read step-by-step guides for Duo camera previews, Smart Take, FaceTime, StandBy, Edge Light, Pencil and accessibility. Features used in Camera, FaceTime or Settings are clearly identified, with links to Apple's instructions. DEVICE REQUIREMENTS Live hinge readings require iPhone Duo. Preview and in-app practice remain available without hinge data on other compatible iPhones. iOS 27.0 or later is required; Duo hinge readings require iOS 27.1 or later. Apple Pencil (USB-C) support on Duo and Edge Light require iOS 27.2 or later; some features require supported accessories or another app. PRIVACY AND PAYMENT The paid download includes all app features.
