Google’s new AppFunctions framework is one of the more important Android developments in a while, because it points to where mobile computing may be heading next: away from tapping through app interfaces and toward asking an AI agent to just handle the task.
Some geek speak: AppFunctions gives developers a structured way to expose app capabilities directly to Gemini — things like creating reminders, adding calendar events, searching photo libraries, or generating playlists. In practice, it’s a bit like bringing the logic of MCP-style tool use (a thing developers use to link tools together) down onto the device itself, making it available to everyone.
What makes this notable is that it changes how and what the user interacts with. The user no longer thinks of which app to use. Ins6ead, the user tells the assistant what (s)he wants and the assistant figures out which app(s) and which function(s) to use. That’s a meaningful shift. If Gemini can reliably complete tasks across multiple apps, the user will work with the assistant rather than any individual app.
Google is also taking a pragmatic approach by pairing AppFunctions with UI automation for apps that haven’t implemented native support for automation. That makes the strategy much more viable in the short term, but it also raises long-term questions: who controls discovery, who owns the user relationship, and how much leverage does Google gain if Gemini becomes the broker for most actions on Android? If this works, it could be one of the clearest examples yet of the operating system becoming agent-first.

The Genesis of ZeroCadence
Back in 2003 I started a blog that was intended to be a collection of short posts. Mostly for me but ideally useful to others, it was a collection of short posts highlighting or discussing a single topic. This newsletter is the evolution of that concept — short posts highlighting what I consider to be interesting and worthwhile tech news items.
This newsletter will always be free but if you like it and you want to show your appreciation, you can buy me a coffee for as little as $1, the suggested $3. or any amount you think appropriate.
And thanks for reading!
