Most productivity tools are so complex that organizing your life starts to feel like one more task on the list. We wanted the opposite: an app where you just speak or type what's on your mind and a calm sidekick, Robin, sorts it for you, gently and with no guilt. We built Robn in SwiftUI, using local AI (Apple Intelligence) to turn messy thoughts into tasks and to suggest when something belongs under a task you already have. A Lock Screen Live Activity counts down to what's next, and a weekly card celebrates small wins. Along the way we learned that on-device AI is powerful enough to be the core of an app while keeping everything private, and that it has to be checked rather than blindly trusted. Our biggest challenge was the AI being "too helpful" and inventing tasks no one said, which we solved by checking every result against the user's own words. It was also hard to decide when something should become a subtask, fitting prompts into a small on-device model, and the realities of testing on real iPhones.
