Spino — sit up, gently

Features

Calibrate once. Forget it's there.

Spino learns how you sit when you sit well, then only speaks up when you drift away from it.

Personal calibration

Sit the way you want to sit for about three seconds. That becomes your baseline — recalibrate any time from the menu bar.

Posture drift

Detects slouching, sideways lean, head tilt and leaning in too close to the screen.

Gentle escalation

Nothing for the first 3 seconds. Then the edges darken, and the screen dims over ten seconds until you straighten up. Max dim is up to you.

Break reminders

After a stretch of sitting (3–120 min, your choice), a small card asks you to stand up. A minute out of frame counts as a break.

Pause when you need to

Snooze alerts for 30 minutes, or pause Spino entirely — the camera stops too. It also pauses on its own when you step away.

Open at login

Optional and off by default. Uses the system's own Login Items list, so you stay in control.

Privacy

Your camera never leaves your Mac.

Not as a promise — as a property of the app. macOS enforces it.

Processed in memoryEvery frame is analysed on your Mac with Apple's Vision framework, then dropped. Nothing is recorded or written to disk.
No network, at allSpino runs in the App Sandbox with the camera as its only capability. There is no networking code, and macOS would block it anyway.
Camera off when you're awayScreen locked, display asleep, Mac asleep or another user logged in — the camera turns off and comes back on its own.
Always visibleA green dot in the menu bar shows exactly when the camera is active.
Almost nothing storedThe only saved data is your calibration: five numbers, their tolerances and a timestamp.
No account, no trackingNo sign-up, no analytics, no telemetry. Just the app.

Install

Up and running in a minute.

Spino isn't from the App Store yet, so macOS asks you to approve it once.

Download and drag to Applications

Open Spino.dmg and drag Spino onto the Applications folder.

Try to open it once

Launch Spino from Applications. macOS will say it can't verify the developer — click Done.

Allow it in System Settings

Go to System Settings → Privacy & Security, scroll down and click Open Anyway next to Spino. Confirm with your password or Touch ID.

Allow the camera and calibrate

Spino lives in the menu bar (no Dock icon). Grant camera access, sit up straight for three seconds, and you're done.

On macOS 14 Sonoma you can skip step 3: right-click Spino in Applications, choose Open, then Open again. You only need to do this once per version.

Sit up, gently.
