Bout Fitness

Most productivity timers split the screen into work and break, and treat the break as the absence of the work. Bout Fitness treats it the other way around: the break is the point. The work happens in Rounds — short, focused intervals — and the Corner is where the day’s movement quietly accumulates between them.

The concept is straightforward. Sit down to work, the app starts a Round. When the bell rings, you don’t leave the desk — you do whatever the Corner is showing: a 60-second mobility flow, a posture reset, a stand-up stretch, a quick walk. By the end of the workday, the desk worker has done what most fitness apps demand a separate 45-minute block for.

Why we built it

Personal-product team move. The Bout Labs team works long sessions at the desk, and watched too many ergonomic + fitness apps fail the same way: they ask for a separate block of time that the user doesn’t actually have. Rounds + Corner sneaks the movement into the work session, where the time was always going to go.

The other half is structure. Pomodoro-style timers are tools without an opinion. Bout Fitness has opinions — about what a good Round looks like, what to do in your Corner, when to push and when to recover. The app is the coach, not the stopwatch.

What’s in it

• A focused-work timer built around Rounds (work) and Corners (active recovery)
• A growing library of Corner exercises — mobility, posture, breath
• Subscription unlocks deeper Corner libraries, personalized Round structure, and longer-term tracking
• Native SwiftUI, no web shell — the app belongs on the platform it runs on
• Optional CloudKit sync — your Rounds follow you between devices
