Works best with AirPods Pro 2 or AirPods 4.

Three steps to sitting tall.

Wear your AirPods

Spine Nudge reads your head angle from the motion sensors in your AirPods. No camera, no desk sensor, no extra hardware.

Sit tall once

Sit up, hold still for a moment, and Spine Nudge learns your upright posture as the baseline.

Forget about it

Work as usual. The Vitality meter drains as you slouch and refills as you sit tall, and when a slouch sticks, a gentle nudge sets you straight.

The calibration window: a figure sits tall at a desk while Spine Nudge holds still to capture the upright baseline.

See it in action.

Watch Spine Nudge catch a slouch, nudge it away, and keep score, all in under thirty seconds.

Sound on: you will hear the chime and the spoken cue.

Built to make sitting well stick.

Nudges

A gentle nudge sets you straight.

When a slouch sticks, Spine Nudge plays a soft chime, says “Sit up straight.”, or both. Choose how quickly nudges escalate (Gentle, Balanced, or Assertive), and snooze them whenever you need a quiet stretch.

A slouching figure at a desk with a “Sit up straight.” speech bubble, a red glow around the scene, and the Vitality meter reading Nudged. Above it: Chime, Voice, and Screen glow.

Screen glow

Keep slouching, and your screen glows red.

Turn on the screen effect and Red Nebula glows in from the edges of your screen while you slouch, then fades the moment you sit tall. Pick when it shows, how fast it builds, and how strong it gets. It is a click-through layer that never reads or captures what is on your screen.

A Mac desktop with a code editor, its edges washed in a red glow while the user slouches.

Widget

Know where you stand.

A tiny widget shows how many degrees you are from your calibrated posture. Park it under your camera, so glancing at it lifts your head instead of dropping it. Past your slouch line, its outline fills like a timer until the nudge, so you can sit up first.

Show it all the time, or only when you start to drift.
Keep it above every window.
Lock it in place so clicks pass through. Locked, it fades while your pointer is over it.

Menu bar

Always on, right in your menu bar.

The spine icon in your menu bar fills and empties with your posture. One click shows your live posture, today’s stats, and your streak, with quick switches for sensitivity, the widget, and the screen effect.

Monitors all day and pauses on its own when your AirPods come off.

Progress

Watch your posture improve.

Today shows your score, your share of good posture, your slouches, and a timeline of your day. Trends adds week, month, and year views, the hours you slouch most, and your hardest weekday.

A daily goal, streaks, and badges to keep you going.
A record of every session.

The Trends window for a month: daily scores climbing toward 93 percent, a chart of the hours you slouch most, and a 12-day streak notification.

Settings

Tune it to you.

Pick how strict detection is: Gentle, Standard, Strict, or your own angle and hold time. Choose how you are nudged and what your screen does. Keep a separate profile, with its own calibration, sensitivity, and nudges, for each place you sit, and switch between them in a click.

Spine Nudge settings: detection sensitivity with slouch angle and hold time sliders, nudge aggressiveness, sound and spoken cue switches, and desktop overlay options.

The little things, handled.

Honest scoring

Time Spine Nudge cannot see you, like AirPods out of your ears, is never counted against you.

Re-centers as you move

Small shifts are re-centered automatically, so you do not need to recalibrate every time you adjust your AirPods.

Badges worth earning

Milestones unlock badges, and a notification lets you know the moment you earn one.

Synced, privately

Your daily totals, goal, streak, and badges sync through your own iCloud. The app works fully without it.

Try it without AirPods

A built-in demo runs the real detection on simulated head motion, so you can see a nudge before your AirPods are in.

No account

Nothing to sign up for. Install it, calibrate, and get back to work.

Your posture is nobody's business.

Spine Nudge never uses your camera. Head motion is processed entirely on your Mac and is never sent to us. Only your daily totals, goal, streak, and badges sync, through your own private iCloud, which we cannot read. No account, no analytics, no ads.
