Notes, tasks and your calendar side by side
On the Duo: Duo-native. Version 3.4.2 (24 October) added iPhone Duo support, its release notes say; its maker's site shows the capture grid across the open Duo's inner screen. Checked November 5, 2026.
App Store data as of October 27, 2026

Capture saves notes, lists and reminders, spots dates and URLs, and exports to other apps, including calendar apps. Badges nudge you about open items, a Share extension takes content from any app, and widgets, Siri, Shortcuts and iCloud sync are included.
Open, the Duo shows your captures beside the one you're reading, with room for its photo, link or note; closed, everything fits the outer display, its release notes say. Its maker shows the capture grid across the full inner screen.
