Caesura is a macOS menu-bar app that reminds you to take six evidence-based breaks throughout the day: hydrate every 45 minutes, walk every 60, roll your wrists every 30, rest your eyes every 20, shift posture every 30, and breathe deeply every 90. Each interval comes from published research, not convenience.

The app respects your flow: it automatically pauses during video calls, screen sharing, fullscreen apps, and focus modes — then picks up exactly where it left off. Overlapping breaks coalesce into a single notification. No account, no telemetry, no subscription.

Choose from three prompt styles per break:

Overlay — a full-screen prompt (for breaks you'd otherwise ignore).
Banner — a gentle slide-in from the menu bar.
Notification — a standard macOS notification.

Built natively with Swift and SwiftUI, Caesura is just 8 MB, cold-launches in under a second, and uses single-digit MBs of RAM when idle. It supports macOS 14+, Apple Silicon and Intel, and is localized in over thirty languages.

One-time purchase of $15 includes a 14-day free trial (no credit card required) and a 30-day money-back guarantee. Updates are free forever.
