Brisbane teen wins Apple's global coding challenge with emotion-management app

Martina Recabarren was fourteen when she decided to build an app for children who didn't know what to do with their anger. She called it Calm Corner, and it worked the way she imagined: a digital space where primary-aged kids could check in with themselves, name what they were feeling, and learn a few simple ways to settle down again. The app was good enough that Apple selected it as one of 350 winning submissions in its 2026 Swift Student Challenge, a global competition that invites young coders to design original playgrounds using Apple's Swift programming language. Martina, a Year 9 student at Siena Catholic College in Sippy Downs, Brisbane, became the only female winner from Australia and New Zealand.

The app itself is straightforward in its ambition. Martina built it to help children manage what she calls "big emotions"—anger, anxiety, the feelings that derail a classroom and send a kid spiraling. Calm Corner walks them through guided check-ins, asks them what's happening inside, and offers calming strategies that actually work for a nine-year-old's brain. The goal is simple: understand the feeling, manage it in a healthy way, get back to learning. It sounds modest, but in a school system where emotional dysregulation is one of the leading reasons kids fall behind, an app that helps a child find their footing again has real weight.

Martina's win is the second consecutive Apple award for Siena Catholic College. Last year, Year 12 student Kobe O'Connor won for an app called Deconstruct. The school's curriculum leader, Paul Dionysius, noticed Martina's coding talent early—back in Year 8, when she first took his Digital Technologies class. He watched her become completely absorbed in the work, coding at every spare moment, pushing beyond what the standard curriculum offered. His job became clear: get out of her way, ask hard questions, give her room to grow. "From the moment she started coding, she was completely immersed," Dionysius said. "It was clear she needed opportunities beyond the standard curriculum."

What strikes Dionysius now is not just Martina's own achievement, but the ripple effect. She's showing other students—particularly young women—that coding and STEM are not distant, abstract pursuits. They're tools you can pick up and use to solve a problem you actually care about. An app for managing emotions is not a theoretical exercise. It's something a real kid might use tomorrow. That visibility matters. In a field where women remain underrepresented, a fourteen-year-old girl winning a global competition sends a message that lands differently than any recruitment poster.

Martina is already thinking ahead. Her next project is more ambitious: an app that controls a robotic arm using wrist motion detected through an Apple Watch. It's the kind of idea that suggests she's not slowing down, not settling into the comfort of one success. She's building on it, reaching for something harder. The question now is what comes after that—and whether the schools and institutions around her will keep making space for her to find out.
