“There’s an app for that” was the promise of the App Store from the very beginning. The app that will get your phone to do the thing you want it to? It’s just a few taps away. The tagline wasn’t strictly true — I’m still waiting for that one perfect grocery list app. Still, apps shaped the modern smartphone into what it is today. We spend all day, every day inside of apps — scrolling, listening, and tapping until we find what we want. But your next favorite app might just be one that you made yourself.

If you weren’t familiar with the concept of “vibe coding” at the beginning of 2026, you probably are now. As AI coding tools have become better and more accessible, more and more non-developers are finding success creating apps that fulfill a niche need. Vibe coders are mostly working with desktop software, but signals from this Google I/O and beyond indicate that mobile will be the next frontier.

For starters, Google is making it easier to just straight up vibe-code a whole Android app. At I/O the company announced an update to its AI Studio vibe-coding tool, allowing you to create a native Android app and export it to a phone in a matter of minutes. The feature is limited to “personal utility” apps to start with, and the rules for putting an app on the Play Store remain the same. But if you’re the kind of person looking for a particular feature from a habit tracking app that none of them seem to offer, you might just be able to build it yourself.

If a whole app feels too ambitious, then maybe a widget is more your speed. At last week’s Android Show, Google announced an upcoming feature to create your own widgets with a prompt — Google’s examples include widgets that highlight certain weather metrics or suggest new recipes to try.

These tools draw on Gemini’s knowledge base, so the possibilities are pretty wide open. Naturally it all depends on this feature actually, you know, working. But the idea of putting the very specific information I want where I want it on my phone is awfully compelling. Not to make too much out of some widgets, but stuff like this has kind of been the whole premise of personal computing for the past couple of decades. If it works as advertised — again, emphasis on if — it kind of unlocks a whole new level of personalization for your phone.

Google calls the AI-generated widgets a first step toward something called a “generative UI,” where your phone creates an interface and apps on the fly based on what you need in the moment. Sounds great in theory! But it also sounds like it could get messy fast. Android president Sameer Samat acknowledges that there’s a pretty obvious way to take the concept too far. “While I don’t think we want to wake up every morning and have our devices have different UI, I do think there’s a level of personalization and customization to the user that could be delightful,” he tells me.
