Compared, fairly
BetterPosture vs Dorso
Dorso is the closest in spirit: local, no account, gentle. It comes as a free open-source build or a $4.99 App Store build, and it can use AirPods instead of a camera. Both offer progress tracking. BetterPosture is free at the core, camera only, and includes local assistant notes.
We make BetterPosture, so read this knowing that. Dorso is one developer's posture app for Mac: a free open-source build (the project formerly called Posturr), a $4.99 Mac App Store build, and an AirPods mode that needs no camera. Prices and claims checked October 2026; every number links to its source at the bottom.
Where Dorso wins
- You do not want to give any app camera access. Dorso can read posture from AirPods instead.
- You want to read the code, or run the free open-source build. BetterPosture is not open source.
- You prefer the Mac App Store or Homebrew for installs and updates.
- You want to pay once and little. $4.99 is less than BetterPosture Pro.
- You work unplugged. Dorso pauses itself on battery; BetterPosture does not yet.
- You want a community. Dorso has a Discord.
Where BetterPosture wins
- One signed download with everything in it, free: calibration, overlay, snooze, Progress. No choosing between a free build and a paid one.
- Calibrated to your own upright and slouch rather than a general idea of good posture.
- A Progress window that answers how today went, how this week compares, and what to do next.
- An assistant that reads daily totals, never frames, and writes one next action.
- A privacy page with every host the app can contact and a Little Snitch test you can run in an hour.
