The new app OS is here. OpenAI’s Sam Altman revealed on Monday that he wants ChatGPT to be the place to use apps in the future. At OpenAI’s Developer Day, he announced a new SDK that lets third-party apps live inside ChatGPT. Think of it like this: instead of jumping between different apps on your phone, you could open ChatGPT and say, “Book me a flight to Paris,” and an integrated app like Expedia handles the UI, the search, and the checkout, all of this within the chat! You could then, without switching your app, ask Booking.com to show you hotels to stay at in Paris, and get your booking done there itself. And then, a Spotify playlist for your short trip to Paris? Sure, why not?What’s fascinating here is the shift from AI as a tool to AI as an operating system. For an app developer like you, that’s both exciting and a little wild. You can tap into ChatGPT’s multimodal stack and create context-aware apps that users interact with conversationally, not through traditional navigation.But here’s the thing: This isn’t the first time OpenAI has taken a shot at this idea. Remember when two years ago, it launched custom GPTs, where you could essentially build-your-own widgets and tweak and publish them to the GPT Store. That concept never really caught fire as the widgets felt limited, siloed, and not deeply integrated with the user experience. Altman’s betting that this time it’ll be different. Will it though? How many of you who experimented with the custom widgets last time around are likely to try the new Apps SDK now? Whether this turns ChatGPT into a mini-app ecosystem or a full-blown operating layer remains to be seen, but it’s clear OpenAI wants you to think conversationally, not just visually, when developing your apps.That’s not all the news this week. Let’s dive in.🚀 OpenAI turns ChatGPT into an app platform: Sam Altman wants ChatGPT to be your new app OS, with third-party apps like Expedia and Spotify living right inside the chat.🔒 Apple’s Foundation Models go on-device: AI gets local with Apple’s new framework, running private and powerful right on your iPhone’s Neural Engine.📲 Android gets its own Handoff: Task Continuity will let you jump between devices like magic, Android 16 is gunning for Apple’s ecosystem edge.🏛️ React gets its own foundation: Meta hands React to a new Linux Foundation home, backed by $3M and an all-star board, open-source just grew up.💻 Google’s Jules hits the command line: Google’s coding agent now runs in terminal and hooks into Slack and GitHub, devs call it smart, but scattered.Stick around for this week’s Developer Tip to learn how to avoid excessive wake locks and improving battery efficiency in your Android apps andtheDid You Know? section to learn how Apple’s iOS 18.6 update reduced the Epic Games Store iOS install flow from 15 steps to 6.Let’s dive in!📱 What's Happening in Mobile Development?If there’s any major news in the world of mobile app dev in the last week, MobilePro has you covered.iOSApple’s Foundation Models framework unlocks new app experiences powered by Apple Intelligence: Apple’s new Foundation Models framework brings intelligence straight to the iPhone’s Neural Engine, no cloud, no GPU, just on-device sorcery.

Do you have any concerns, advice, or tutorials to share?MobileProbrings them to you all in one place.Live Activities reimagined as visual micro-storytelling: If you’re already using Live Activities, think of them less as widgets and more as visual micro-stories that evolve with user context. The piece dives into when they truly shine and how to keep them meaningful through smart hierarchy, smooth transitions, and avoiding “always-on” fatigue that turns delight into distraction.iOS devs debating Liquid Glass adoption: are they really on board?: A lively Reddit thread shows the community is split; some devs whisper excitement over the fresh design, others slam it for readability, performance hits, and visual discomfort, especially in dark mode. It’s become a lightning rod for deeper questions about how far designers should push aesthetics on mobile UI.Google tests “true” edge-to-edge layout in Chrome Canary: In a Reddit post, users noticed Chrome Canary is experimenting with full edge-to-edge rendering where content flows behind both the navigation and status bars, though the implementation is shaky and buggy so far.Android developer verification clarified: your top questions answered: Android’s new developer identity rules aim to protect users without killing sideloading or day-to-day dev workflows, and Google reassures that Android Studio builds, testing, and debugging remain unaffected.Derived Data mistakes every iOS dev should avoid: Antoine van der Lee breaks down five common missteps: misunderstanding Derived Data’s purpose, manually hunting for its folder, recklessly deleting everything, ignoring build-time insights, and failing to inspect build output for hidden inefficiencies.App monetization strategies: how to pick the right mix for your app: This article walks through real-world trade-offs, like ad fatigue vs. subscription churn, and shows that layering multiple revenue streams, whether subscriptions, ads, freemium upgrades, or sponsored content, often yields the best balance for long-term growth.Flutter team seeks your feedback to improve accessibility: With accessibility standards like EAA and WCAG becoming more critical, Flutter wants to help developers catch issues earlier instead of fixing them right before release. The team is asking for input on pain points, success stories, and tools that could make accessibility debugging more proactive and integrated into everyday development.📚️ Latest in Mobile Development from PacktMobilePro presents the latest titles from Packt that ought to be useful for mobile developers.Available now in Early access, Ahmad Sahar's book is perfect for beginners with minimal coding experience who want to enter the world of Swift programming and iOS app development.🏗️Have fun building your first iOS app and start your iOS programming career🤖 Learn to integrate Apple Intelligence and the sleek new Liquid Glass UI for modern app experiences📚 Establish a solid foundation with UIKit, testing, and deployment best practicesiOS 26 Programming for BeginnersLimited-time offer: 30% off for 72 hours!
