Compared, fairly

The best posture app for Mac depends on what you want.

Fourteen apps, prices with a date on them, and a straight answer for each kind of person. We make one of these apps, so the fair thing is to show you the whole field and say where the others are better.

Pick by what you want

Open source you can read and build: Dorso's free build (the project formerly called Posturr), PostureCV, or PostureGuard. Compare
No camera at all: Posture Pal, AirPoise, or Dorso's AirPods mode. Compare
Windows or Linux as well as Mac: SitApp or SuperShrimp run on all three. Slouch Sniper covers Mac and Windows. Compare
The cheapest paid app, bought once: Dorso at $4.99 on the App Store, or its free open-source build if you can skip the polish. Compare
A game: SuperShrimp, with XP, levels and a leaderboard. Postura leans the same way. Compare
A nudge calm enough to keep running, tuned to your own desk: BetterPosture. Free at the core, calibrated to you, one overlay, no streaks.
To avoid a subscription: Dorso, SuperShrimp, Slouch Sniper and BetterPosture are free or one-time. Posture Reminder AI, SitWit and SitApp's monthly plan bill you every month. Compare

How we judge a posture app

The same four questions we hold our own app to.

Is it calibrated to you?

A fixed idea of good posture breaks the moment your camera sits at an angle. The app should learn your upright and your slouch.

Will you keep it running?

Blurred screens, meowing cats and streaks feel motivating for a week. The test is whether it is still running in month three.

Can you check the privacy claim?

Every app on this list says it is local. The good ones let you verify it: open code, or a page that lists every host and a firewall test.

Does the price match the software?

An app that runs on your own Mac has no server bill. A one-time price, or free, is the honest shape. A subscription needs a reason.
