Caesura is a menu-bar app for macOS that reminds you to take six kinds of breaks: drink water, walk, stretch your wrists, rest your eyes, check your posture, and breathe. Each one runs on its own schedule, and every default interval comes from a specific study rather than a number I made up.
The problem with running six timers is obvious: on a busy day they gang up on you. Caesura merges any reminders that land within two minutes of each other into a single prompt, so you get one interruption instead of three back to back.
It also knows when to shut up. When your camera is on, you're sharing your screen, an app is fullscreen, or Do Not Disturb is active, every timer pauses and picks up where it left off. It can watch your local calendar too, if you let it.
A few things it deliberately doesn't do:
- No subscription. You buy it once, updates are free.
- No account, and the 14-day trial never asks for a card.
- No health theater. The Evidence page lists what the research actually supports, including the claims this app refuses to make.
