How does unhunch measure posture score?

unhunch uses your webcam to detect key skeletal landmarks — ears, shoulders, hips — and calculate their angles in real time. All pose detection runs on-device via MediaPipe; no video is uploaded or stored. At setup, you calibrate a personal neutral position, and your live score reflects how closely your current posture matches that baseline. The score updates continuously and triggers a slouch alert when you drop below your set threshold.

Will watching my posture score actually improve my posture?

Watching the score alone creates short-term awareness but rarely changes long-term habits. The more effective approach is to use alerts as a trigger: when the score drops, correct your position, then return to your work. Over time, corrections become automatic. The score works best as a background accountability layer — something that catches drift before it becomes hours of sustained misalignment, not a number to monitor continuously.

Why is maintaining good posture so challenging without continuous feedback?

Your body adapts to repeated positions through a process called proprioceptive habituation — your brain becomes less aware of your actual posture the longer you hold a position. This is why many people don't notice when they start slouching after 30 minutes of work; it feels normal to them because their nervous system has adapted. Without external feedback, your body defaults to comfortable (but poor postural) positions rather than upright ones. Unhunch solves this by providing real-time feedback, interrupting the adaptation cycle and keeping your postural awareness sharp throughout your workday.

Does unhunch work effectively if I work from different locations with varying setups?

Yes. Because unhunch runs entirely on your device using your webcam, it doesn't depend on a specific desk setup or environment. The on-device pose detection system adapts automatically to your camera angle and surroundings, whether you're at your home desk, an office, a coffee shop, or a co-working space. Unhunch analyzes your body's alignment relative to your own anatomy and current position, not a fixed reference environment, so it provides consistent posture coaching regardless of where you're working. This makes it ideal for people who split their time between multiple locations.

What Is a Good Posture Score — and How Is It Measured?

Q: What is a good posture score?

A posture score of 80–100 is generally considered good : the head is balanced over the shoulders, the spine maintains its natural curve, and there is minimal sustained load on the neck and lower back. Scores from 60–79 indicate mild misalignment — forward head posture or rounded shoulders — worth correcting when noticed. Scores below 60 reflect significant slouch and prolonged muscle strain.

A posture score is a real-time 0–100 rating of how closely your seated position matches a neutral spine alignment. Scores above 80 are generally considered good; anything below 60 signals significant slouch worth correcting.

WHAT COUNTS AS A GOOD POSTURE SCORE

A posture score is a 0–100 index that measures how far your head, neck, and spine deviate from a neutral seated position. 80–100 is good: head over shoulders, spine in its natural curve. 60–79 is fair: mild forward head or rounded shoulders that should be corrected. Below 60 is poor: significant slouch that puts sustained load on the neck and lower back. unhunch calculates its score on-device using your webcam and MediaPipe pose detection — no video is ever uploaded. The score updates in real time so you see the exact moment alignment slips.

Scores of 80–100 indicate good alignment; 60–79 is fair; below 60 needs attention.

A score is most useful paired with alerts that catch slouching as it happens.

How Posture Apps Calculate a Score

Posture apps use a camera to identify key body landmarks — ears, shoulders, hips — and compute the angles between them. The two primary signals are head-forward distance (how far your ears sit ahead of your shoulders) and spinal curvature (whether your lower back has rounded). These measurements are compared against a neutral baseline set during calibration. The further your joints deviate from that baseline, the lower your score. unhunch runs this detection entirely on-device via MediaPipe — your video never leaves the browser, so scores update in real time without any server round-trip.

What a Score of 80 or Above Looks Like in Practice

An 80+ score means your ears are roughly aligned over your shoulders, your lower back keeps a gentle inward curve, and your screen is at or near eye level. This is not a rigid military stance — small, natural movement is fine and even beneficial. The goal is avoiding sustained deviation: the kind where your chin juts forward, your shoulders round inward, and your upper back slumps for 30 minutes without correction. A score in the 80s lets you shift slightly, lean in to read, or tilt your head without triggering an alert — it flags the drift that matters, not every micro-movement.

Why Your Posture Score Drops Over the Course of a Day

Posture scores fall as the day progresses for two main reasons: muscle fatigue and cognitive load. The muscles that hold your head upright and maintain lumbar curve tire after hours of sustained effort. At the same time, focused work pulls attention away from physical awareness, so slouching begins without conscious notice. Most people are at their worst in the hour after lunch and in the final two hours of the workday. Tracking a score over time makes this pattern visible — you can see exactly when your alignment breaks down and decide where to add a movement break.

Personal Calibration: Why Your Baseline Matters

A fixed universal posture standard does not account for differences in body proportions, seating height, or camera angle. That is why calibration matters. When you set your neutral position in unhunch, the app measures your specific joint angles at a comfortable, upright posture and uses those as the reference point. Later deviations are scored relative to your baseline, not a generic model. This means a person who naturally sits with a slight forward lean will not be penalized for it — only unintended drift from their own neutral triggers a lower score.

How to Use Your Score to Build Better Posture Habits

The score is a feedback signal, not a goal in itself. The most effective approach is to set a threshold alert — in unhunch this is the slouch alert — and let it fire when your score drops. Correct your position, then return to work without watching the number. Over days and weeks, the alerts become less frequent as corrections become automatic. Pairing the score with a brief movement break every 30–60 minutes handles the fatigue side: a short walk or stretch resets muscle tension so you can hold a neutral position more easily.

Set your neutral position during calibration, seated comfortably upright.
Enable slouch alerts so correction happens in the moment, not after an hour.
Take a 2–5 minute movement break every 30–60 minutes to reset muscle fatigue.
Review score trends weekly to spot which times of day your alignment slips most.
