Does unhunch work with a MacBook's built-in webcam?

Yes. unhunch runs in Chrome or Edge and uses whatever webcam your Mac already has — built-in or external. There's nothing to install: open the page, allow camera access, and it starts scoring your posture and sending slouch alerts immediately, with all processing happening on-device.

Do I need to download a Mac app to get slouch alerts?

No. unhunch runs entirely in your browser (Chrome or Edge), with no download and no signup required to start. It watches your posture through your webcam, scores it from 0–100, and alerts you with sound and an on-screen notification the moment you slouch — all without leaving the page.

How much does unhunch cost, and can I try it first?

unhunch offers a 30-day free trial with no credit card required. After that, it's a one-time payment of $14.99 for lifetime access — not a subscription — backed by a 7-day money-back guarantee.

Why are regular posture breaks important, and how frequently should I take them?

Maintaining the same posture for extended periods—even good posture—fatigues your muscles and reduces your awareness of when you're slipping into poor habits. Taking short breaks to move, stretch, or briefly change position gives your postural muscles a chance to recover and resets your body awareness. Common guidance suggests a break every 30 to 60 minutes, even if it's just a minute or two of standing, walking, or light stretching. These micro-breaks interrupt the pattern of static tension and help prevent the cumulative strain that develops over hours of sitting. Beyond the physical benefit, movement breaks also boost circulation and mental clarity. Frequent small adjustments and position changes are often more effective at preventing discomfort than trying to maintain "perfect" posture continuously—which isn't realistic or healthy.

What's the connection between poor posture and headaches or neck tension?

Your neck muscles are in constant use to support the weight of your head. When your head is in a neutral, balanced position—stacked over your shoulders—these muscles work efficiently. But when you crane your neck forward to see a screen that's too low, tilted down to look at a phone, or held to one side, your neck muscles must work much harder to maintain that position. This sustained muscle tension restricts blood flow, can pinch nerves, and contributes to headaches that often feel like they originate in the back of your head or behind your eyes. Even small forward head posture increases the load on your neck exponentially—a few inches of forward lean can substantially increase the effective weight your neck is supporting. Over hours of work, this tension accumulates and can trigger tension headaches or chronic neck pain. Correcting your screen height and viewing distance, along with overall spinal alignment, often alleviates this type of headache.

A Mac posture app that catches your slouch and alerts you instantly

unhunch is a browser-based posture app that works on Mac in Chrome or Edge: it watches your posture via webcam, scores it 0–100, and fires a sound plus notification the instant you slouch — no download, no signup.

THE SHORT ANSWER

unhunch runs right in Chrome or Edge on Mac — open the page, allow webcam access, and it starts scoring your posture from 0–100 in real time. No download or signup is needed. When your posture drops past your calibrated threshold, it plays a sound and shows an on-screen alert, and an always-on-top floating monitor (Chrome and Edge) keeps your live score visible while you work in other apps. All pose detection runs on-device with MediaPipe, so your webcam video never leaves your Mac.

Works in Chrome or Edge on Mac — no download, no signup, nothing to install.
Sound and on-screen alerts fire the moment your posture score drops.
An always-on-top floating monitor keeps your score visible in other apps.
All pose detection runs on-device — your webcam video is never uploaded.

How does an app know you're slouching, anyway?

A posture app that catches slouching needs two things: a way to see your posture and a way to tell good from bad. unhunch uses your webcam and on-device pose detection (MediaPipe) to track your head and shoulder position, then compares it to a baseline you set during a short calibration. When you drift far enough from that baseline for long enough, it counts as a slouch and triggers an alert — a sound plus an on-screen notification — rather than waiting for you to notice the ache yourself.

Setting up slouch alerts on a Mac

Getting alerts running takes a few minutes, and there's nothing to install. Open unhunch in Chrome or Edge, grant camera access, and sit the way you normally would — that becomes your reference posture. From there the app scores you continuously and tells you the moment you slip.

Open the site in Chrome or Edge on your Mac — no download or account needed.
Allow webcam access when prompted; your video stays on your machine.
Sit in your normal working posture and run the short calibration.
Keep the floating monitor on top of your other windows for a constant glance at your score.
Let sound and notification alerts catch the slouches you'd otherwise miss for hours.

Why on-device processing matters for a webcam posture tool

Any tool that watches you through a webcam raises an obvious question: where does that video go? With unhunch, the answer is nowhere — every frame is processed locally by MediaPipe, and nothing is uploaded or stored. That matters doubly on a personal laptop, where the webcam often points straight at your home office or living room. You get the benefit of continuous visual feedback without handing footage of yourself to a server.

Posture app or wearable posture corrector — which actually catches the slouch?

Wearable correctors buzz against your back when you round your shoulders, but they only know about that one joint, and many people stop wearing them within weeks. A webcam-based posture app instead watches your whole upper-body alignment — head, neck, shoulders — from a normal working distance, with nothing strapped on. The trade-off is that it only sees you while you're at your desk and in front of the camera, which is, for most knowledge workers, most of the working day anyway.

A setup fixes posture once; feedback keeps it fixed

Raising your monitor and adjusting your chair gets your desk into a good neutral position — but nothing about a good chair stops you from leaning toward the screen an hour into a focus session. That's the gap unhunch is built for: it watches quietly in the background and tells you the moment your posture drifts, so the good setup you already built keeps doing its job through the whole day, not just the first ten minutes of it.

Make your good posture habits stick

A clean desk setup is the foundation; unhunch is the layer that keeps you honest through the workday, watching quietly via your webcam and alerting you the moment you slouch. Try it free for 30 days, no credit card, then keep it for a one-time $14.99 with a 7-day money-back guarantee.
