## What is Duo Scope?

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. There are no subscriptions, in-app purchases, ads or accounts. Your saved note, progress and preferences stay on your device. Privacy and support includes a control to delete saved data.
