StopSlouching vs Nekoze.
Both watch your posture through your webcam, on-device, and nudge you when you slouch. Nekoze is a free, much-loved Mac-onlymenu-bar app that gives you a playful nudge; StopSlouching is a cross-platform coach that adds real scoring and a guided stretch. We make StopSlouching — here's the honest trade-off.
Short version: if you're on a Mac and want a free, charming reminder, Nekoze is great. If you're on Windows, want guided stretches and a calibrated score, or want to try without installing anything, StopSlouching is built for that.
- Pick Nekozeif you're on macOS, want it free, and like a simple, charming menu-bar nudge with nothing to configure.
- Pick StopSlouchingif you're on Windows (Nekoze doesn't run there), want a guided stretch instead of just a nudge, want a calibrated head/shoulder/upright score, or want to try it in your browser with no install.
How they work
Both detect your posture from your webcam with an on-device model, so the camera feed never leaves your computer. The difference is the shape of the product. Nekoze is a free macOS menu-bar app that gives you a quick, playful reminder when you slump — simple, light, and Mac-only. StopSlouching runs in the browser (open a tab, grant the camera, you're coached in about ten seconds), with an optional native Windows tray app and a Chrome extension for cross-tab detection.
The other difference is what happens when you slouch. Nekoze nudges you. StopSlouching scores your posture against a baseline you calibrate, breaks it into head / shoulder / upright sub-scores, and serves a specific 30-second stretch for whichever one is slipping.

What StopSlouching does better
- It runs on Windows. Nekoze is Mac-only. StopSlouching ships a native Windows tray app, runs in any Chromium browser, and has a Chrome extension — so it works whatever you're on.
- It coaches, not just nudges. When you slouch you get a specific 30-second stretch chosen for whichever sub-score (head, shoulders, uprightness) is weakest — not only an alert.
- Calibrated scoring. It learns your neutral and scores drift from it, so you can actually see your posture trend over a session instead of guessing.
- Nothing to install to try it. The whole app is a web page — the fastest way to see if webcam coaching works for you.
What Nekoze does better
- It's free. No paid tier to think about. If you just want a basic nudge and never want to pay, that's hard to beat.
- It's charming and simple. The playful menu-bar character is genuinely delightful, and there's almost nothing to set up.
- It's a native Mac citizen. A lightweight menu-bar app that feels right at home on macOS.
