Caesura is a native macOS menu-bar app that delivers six science-backed break reminders—water, walking, wrist stretches, eye rest, posture shifts, and breathing exercises—each on intervals supported by specific studies. It intelligently pauses timers during calls, screen sharing, fullscreen apps, and focus modes, and coalesces overlapping breaks into a single prompt.
Key features:
- Six evidence-based breaks: Each with a default interval from peer-reviewed research (e.g., water every 45 min, eyes every 20 min).
- Smart auto-pause: Detects camera, screen sharing, calendar events, fullscreen apps, and Do Not Disturb; timers freeze and resume seamlessly.
- Three presentation styles: Full-screen overlay, menu-bar banner, or standard notification—configurable per break.
- Native performance: Written in Swift/SwiftUI, 8 MB binary, universal binary for Apple Silicon and Intel, cold-launches under a second.
Target audience: Mac users who spend long hours at a computer and want unobtrusive, research-backed reminders to maintain physical well-being without disrupting workflow.
