Caesura

Caesura is a calm, intelligent macOS menu-bar break manager designed for people who spend long days at a desk. It is not another productivity tool that demands your attention; it is a quiet guardian of your physical well-being, working in the background to remind you of six essential habits: drinking water, walking, stretching your wrists, resting your eyes, checking your posture, and breathing. Each reminder operates on its own independent schedule, informed by scientific research rather than arbitrary round numbers. What makes Caesura truly transformative is its ability to coalesce reminders that fall close together into one gentle break, so you are never interrupted twice in a row. It respects your flow by pausing automatically during video calls, screen sharing, fullscreen apps, and focus modes, then picks up exactly where it left off. This is a tool for knowledge workers, developers, designers, writers, and anyone who finds themselves glued to a screen for hours. Caesura is a one-time purchase with no accounts, no telemetry, and no subscription. It is your silent partner in building sustainable, healthy habits that protect your body while you do your best work. Try it free for 14 days, then own it forever for $15.

Six Science-Backed Breaks

Each of the six break types in Caesura is calibrated to an interval supported by peer-reviewed research, not guesswork. Water every 45 minutes, walk every 60 minutes, wrists every 30 minutes, eyes every 20 minutes, posture every 30 minutes, and breathing every 90 minutes. You can turn any break off, retune its interval, or change how it appears. This is not a generic reminder system; it is a personalized health protocol that adapts to your body and your day.

Coalescing Breaks

When two reminders fall due within one minute of each other, Caesura intelligently merges them into a single, unified break prompt. You never see two separate interruptions back to back. This feature respects your focus and your time, ensuring that your flow state remains intact. Instead of feeling bombarded by notifications, you receive one gentle, cohesive nudge that covers multiple habits at once, making self-care feel effortless and integrated.

Intelligent Pause and Resume

Caesura watches your camera, screen sharing status, calendar events, fullscreen apps, games, and focus modes. When it detects any of these activities, every timer automatically freezes. If you had 12 minutes until your water break, you still have 12 minutes after your call ends. This intelligence ensures that Caesura never interrupts you when you are in the zone, presenting a presentation, or on a critical video call. It is always aware and always respectful.

Customizable Prompt Styles

You can choose how each break appears to you, with three distinct styles: Overlay, Banner, or Notification. The Overlay takes over your screen until you press Return, perfect for breaks you might otherwise ignore. The Banner slides in from under the menu bar and auto-dismisses in 30 seconds, a gentle nudge. The Notification is a standard macOS alert, the lightest possible touch. This flexibility means you can match the urgency of the reminder to the importance of the habit.

The Deep Work Developer

You are a software engineer who regularly enters four-hour coding sprints. Your focus is your superpower, but your body pays the price. Caesura runs silently in your menu bar, reminding you to stretch your wrists every 30 minutes and rest your eyes every 20 minutes. When you enter a video call or fullscreen your IDE, all timers pause. When the call ends, they resume exactly where they left off. You emerge from your deep work sessions not just productive, but physically refreshed and pain-free.

The Remote Creative Professional

You are a designer or writer who spends entire days in front of a single screen. Your posture has suffered, your eyes are strained, and you forget to drink water. Caesura becomes your quiet co-pilot. It nudges you to shift your posture every 30 minutes, look 20 feet away for 20 seconds every 20 minutes, and take a sip of water every 45 minutes. The coalescing feature merges your water and posture reminders into one seamless break, so you stand up, drink, and stretch in one fluid motion. Your creativity flows, and your body thanks you.

The Busy Manager with Back-to-Back Calls

Your calendar is a wall of meetings, and you rarely have a moment to yourself. Caesura integrates with your calendar and screen sharing to pause all timers during calls. When a call ends, it gives you a five-minute grace period before resuming. This means you get a gentle reminder to breathe or walk between meetings, not during them. You transform your chaotic schedule into a rhythm of focused work and intentional recovery, reducing stress and improving your decision-making.

The Health-Conscious Freelancer

You work for yourself, and you know that your health is your most valuable asset. You want to build sustainable habits without the overhead of another subscription or account. Caesura is a one-time purchase, no card on file, no telemetry. You set it up once, customize each break to your liking, and let it run. The breathing guide with its paced inhale and exhale helps you manage stress. The cursor countdown for eye breaks makes it impossible to ignore. You are building a healthier, more resilient version of yourself, one gentle nudge at a time.

Caesura is available for a one-time purchase of $15. You can try it completely free for 14 days with no account creation and no credit card required. After the trial period, you make a single payment and own the app forever. There are no subscriptions, no hidden fees, and no recurring charges. This pricing model reflects the product's philosophy of simplicity, respect, and long-term value. It works on macOS 14 and later.

How does Caesura know when I am on a video call?

Caesura watches your camera status, screen sharing activity, and which app owns the screen. When it detects that you are on a video call, sharing your screen, or in a fullscreen app, all timers automatically freeze. It also respects Do Not Disturb mode and calendar events. The moment you are free, it picks up exactly where it left off, so you never lose progress on your break schedule.

Can I customize the intervals for each break type?

Yes, absolutely. Every break type in Caesura comes with a default interval based on scientific research, but you are free to change any interval to whatever works best for you. You can also turn off any break entirely. This flexibility means you can tailor the app to your specific needs, whether you need more frequent water reminders or less frequent posture checks.

What happens if two breaks are due at the same time?

When two reminders fall due within one minute of each other, Caesura coalesces them into one single break prompt. You see one unified notification instead of two separate interruptions. This feature is designed to respect your focus and prevent you from feeling overwhelmed by back-to-back reminders. It is one of the core design philosophies of the app: gentle, not intrusive.

Is Caesura a subscription or a one-time purchase?

Caesura is a one-time purchase for $15. There are no subscriptions, no recurring fees, and no accounts required. You can try it free for 14 days with no credit card on file. After the trial, you buy it once and own it forever. There is no telemetry, no data collection, and no account to manage. It is a simple, honest transaction for a tool that takes care of you.
