Who is actually free right now?
The idea
Who's Out started with a simple question: "Who is actually free right now?" We wanted to make it easier to meet people in real life without having to text everyone, check calendars, or figure out where they are. We built it for an IndeHub WWDC26 challenge around the new capabilities coming to iOS 27, which gave us a chance to explore what happens when the operating system can understand more about your personal context.
Instead of asking someone to manually mark themselves as available, Who's Out tries to figure it out. It brings together things like calendar events, location, and Focus modes to understand whether someone is likely to be free. Over time, it can learn patterns around when you tend to be available, making the answer less like a calendar lookup and more like a personal understanding of your routine.
The build
We also wanted the interaction to feel natural. With App Intents and Siri, you can ask Who's Out about your friends or tell it what you want to do without having to open the app and navigate through it. Apple's new App Intents system is designed to make app content and actions available to Siri and Apple Intelligence through natural language.
My role was designing the core architecture and building the systems that connect all of this together — from interpreting availability and combining the different signals to integrating App Intents, Siri, location, calendar and Focus data.
What I learned
The idea was to make the app feel less like another social network and more like a small layer of intelligence that quietly answers a question you already have: "Can we hang out?"
