531 Focus
A native iOS timer for structured deep-work intervals. Built in Swift and UIKit so a session starts in one tap, with history kept locally in CoreData and nothing on screen except the session you are in.
The challenge
Knowledge workers struggle to protect long, uninterrupted stretches of deep work. Existing timers add friction and visual noise that pull attention away from the task rather than toward it.
Our approach
We designed 531 Focus around a single, calm focus loop and built it natively in Swift and UIKit so interactions feel instant. CoreData keeps session history local and private, and the interface strips away everything that is not the current session.
The outcome
The result is a distraction-free iOS timer that makes structured focus intervals effortless to start and easy to sustain, with a clean interface that stays out of the user's way.
