Apple’s foldable iPhone Duo ships as AI’s UX limits come into focus

Apple’s first foldable iPhone reached stores worldwide, alongside optimized apps and new Figma frame presets. AI tools expanded workflow automation and prototyping, while UX findings exposed inflated synthetic-user scores and uneven benefits for practitioners.

Key developments

iPhone Duo reaches stores

Apple launched iPhone Duo at stores worldwide on October 23 and announced apps and games optimized for its first foldable iPhone starting that Friday. Figma also added iPhone Duo and iPhone 18 presets wherever mobile frames can be selected.

Designers can now evaluate the shipping foldable and prototype for its form factor in their existing workflows.

Synthetic users inflate usability scores

Digital twins systematically overestimated System Usability Scale scores for business software in MeasuringU’s findings.

Synthetic-user assessments can make business software appear easier to use than it is.

Linear automates connected workflows

Linear Loops can now start automatically from Slack and GitHub events. Teams can also share Loops as templates and customize their reasoning levels.

Connected-tool updates can trigger reusable workflows instead of waiting for a person to start them.

AI saves time but disappoints practitioners

AI saves UX practitioners time on nearly every task, according to practitioner research, but most feel lukewarm about it. Mandates, unreliable output and inflated expectations eat into the gains.

Faster task completion does not necessarily translate into a better working experience for UX practitioners.

Figma grounds its agent in design rules

Figma published guidance on making design-system principles and guidelines useful to its agent, giving it context about the product it is working on.

Established product rules can provide a reference for agent-generated design work.

Cockpit prototypes become more dynamic

Lufthansa Systems used Figma Make to create more dynamic prototypes for testing in-flight software that helps pilots navigate routes, monitor air traffic and avoid turbulence.

Pilots can test more realistic interface behavior rather than relying solely on static screens.

Default AI chat interfaces face scrutiny

Two commentaries challenged adding AI interfaces without a clear user need. They advocated useful features built with AI rather than standalone AI features and offered six questions for assessing conversational layers for professional users.

An added chat layer can introduce friction into professional workflows rather than improve them.

CSS adds controlled visual variation

Brecht De Ruyte demonstrated CSS random() through organic typography, bouncing letters and splayed cards, exploring variation within design-system constraints.

These effects can be created without JavaScript libraries or extensive generated CSS.
