Liquid Glass and the future of mobile UX
First up, Appleās WWDC kicked off this week and compared to the other recent events from Google, Microsoft (and even Dyson!), this one felt strangely flat. There was an undercurrent of ādonāt mention AIā and some of the announcements that were made didnāt quite hit the mark. On the plus side, iPad OS finally seems to have nailed multi-tasking and Apple Wallet got some neat Digital ID support updates.
But for product teams, of course, the most significant announcement is the all-new design language that Apple is calling Liquid Glass. Many companies have tried and failed to do this, the most notable being Microsoftās Windows Vista. To be fair to Apple, many of the issues with Vista glass effects UI were related to processor limitations that Apple users in 2025 are unlikely to run into.
The main concern though, is accessibility. And because of this, the reaction to Liquid Glass has been mixed to say the least. But if you are curious about what a Liquid Glass-ified version of your own product might look like, Appleās comprehensive design guidelines are worth a read. Some of the most important of these guidelines include:
Moderation in Design - avoid overusing Liquid Glass to maintain content focus. Apple says that designers have noted readability issues with excessive translucency, so prioritize clarity. Plenty of social media posts make this point pretty clear.
Test with Accessibility Settings - ensure interfaces adapt to settings like āReduce Transparencyā or āReduce Motion.ā Standard components handle these automatically, Apple says, but custom elements must provide fallback experiences (e.g., reduced animations or opaque backgrounds).
Minimize Custom Backgrounds - avoid custom backgrounds in controls, navigation elements, or views (e.g., split views, tab bars, toolbars) to prevent interference with Liquid Glassās translucency and scroll edge effects. Let the system handle background appearances.

The Browser Company has officially released Dia in a beta for existing Arc users, the agentic browser set to replace Arc. Iāve been playing around with it for the past few days and so far, so good. Itās still a little bit buggy since itās only a beta version but Iāve found it to be super helpful for things like chatting with PDF reports or summarizing long articles. The UX strays far enough from Chrome to make it feel different but not so far as Arc did to make it feel like a challenge to switch. See some of these use cases in action here.
Googleās Gemini has released Scheduled Actions on its mobile app - a new feature that allows you to ask Gemini to perform a task at a specific time. For example, you can ask it to provide a summary of your upcoming meetings or unread emails every morning. Gemini has also been added to Google Forms which lets you summarize responses and Google Sheets now lets you edit charts created with generative AI.
Googleās VP of Gemini Josh Woodward also unveiled big updates to its Veo3 video generation which lets users generate videos 2x faster.
A new AI Agent called Clark has been released by AI startup Superblocks. Clark is designed for product teams to build internal apps quickly. Users simply describe the type of internal apps they want to build and Clark handles the rest.
Is Meta falling behind?
Meta seems to be falling behind in the AI arms race and this week announced $15bn in funding into AI data labelling startup Scale AI to build an AI āsuper intelligenceā team. Meanwhile, its users seem to be quite confused about how the Meta AI public feed works. There have been several examples of users posting personal, private information on Meta AIās public feed which shows that some users are very confused about the prospect of a public feed integrated into these tools.
WhatsApp is getting AI-powered summaries on mobile. New leaks show that once activated, if thereās a large enough message backlog, a new āSummarize with Meta AIā button appears in place of the usual āX unread messagesā label. Tapping it returns a brief recap of the conversation.
