SpineSpy: a free macOS menubar app for posture reminders, no camera or cloud needed
SpineSpy sits quietly in your Mac's menubar and nudges you to fix your posture or take breaks at set intervals. It works entirely on your device — no camera, no internet, no account required.
SpineSpy is a local-first macOS app, meaning everything it does stays on your Mac. There's no cloud service tracking you and no camera watching your posture — instead, it uses simple timers to remind you to sit up straight or rest your eyes at whatever interval you choose.
For anyone running a Mac mini as a home server and spending long hours in front of it, this is a practical, zero-friction tool. It's open-source, so the code is publicly available for anyone to inspect or modify. Setup is lightweight and it lives unobtrusively in the menubar without slowing your machine down.
