Compare quiet reminders with points, levels, and scores.
Plumb clears its reminder when you sit back up. SuperShrimp turns posture into a game with scores, XP, levels, and a leaderboard.
SuperShrimp requires no wearable; built-in, USB, or Continuity Camera support. It supports macOS, Windows, and Linux. Check whether that hardware and platform setup works at the desk where you need reminders.

A quiet cue appears after you remain slouched and clears when you return to the upright position you recorded.
The first week
How each product sends posture feedback
Plumb begins by asking for three examples from your real desk setup: upright, your natural slump, and the position you use when looking down. That gives the app a personal reference before it starts coaching. You then begin a monitoring session and continue working while classification stays on the Mac.
Plumb ignores brief movements. A quiet reminder appears after your posture stays outside the calibrated range. The reminder clears after you return, and Plumb records the recovery.
SuperShrimp uses camera-based scoring; the public page does not describe a comparable three-pose calibration. During use, it relies on webcam analysis using on-device AI and responds with a notification with posture preview when the score drops.
Plumb records posture time, recoveries, and longer-term patterns on your Mac. SuperShrimp offers good versus bad posture time, daily and weekly scores, XP, ten levels, and a leaderboard. Compare the reports and decide which measurements you would use.
Plumb waits, reminds you, and records recovery
A quiet cue appears after sustained slouching and clears after you return to your calibrated range.
Visible scores and game mechanics that reward consistency
Main drawback: More visual feedback, competitive mechanics, and account-like concepts around a posture habit.
The coaching experience
Choose private recovery tracking or visible game rewards.
Plumb waits to see whether a posture change lasts, then shows one quiet cue. The delay prevents brief reaches, reading positions, and normal movement from triggering alerts.
SuperShrimp responds with a notification with posture preview when the score drops. Its main advantage is visible scores and game mechanics that reward consistency. Its main drawback is more visual feedback, competitive mechanics, and account-like concepts around a posture habit.
After a Plumb reminder, returning to your calibrated range clears the cue. Plumb stores posture time, recoveries, and longer-term patterns on the Mac.
Record three positions, start monitoring, and receive a cue after you remain slouched for the delay you selected.
Pick your trade-off
Compare the daily setup and maintenance
- Want quiet reminders without scores or a game.
- Prefer private local progress without a leaderboard.
- Want three-pose personal calibration.
- Want a no-card trial before purchase.
- Respond to XP, levels, and visible scores.
- Need Windows or Linux support.
- Want a one-time lower launch price.
- Prefer detailed daily and weekly scoring.
Plumb only works on Mac and needs a clear camera angle. SuperShrimp has this drawback: more visual feedback, competitive mechanics, and account-like concepts around a posture habit.
Privacy and setup
Compare camera, device, and account privacy
Plumb uses the Mac camera to compare your current head and shoulder position with the three positions you recorded. It processes frames on the device, discards them during use, and keeps posture history on the Mac. Camera images and posture history are excluded from diagnostics. No account is required for the three-day trial.
That model still has a clear requirement: you must be comfortable granting camera access and have an angle that can see your working position. If your camera is closed, obstructed, or pointed away while using an external display, Plumb cannot coach the session properly.
SuperShrimp has this setup requirement: No wearable; built-in, USB, or Continuity Camera support. Its documented privacy position is on-device, offline detection; no webcam images are captured or stored. For some buyers, that removes the permission they care about most. For others, it adds hardware, account, sync, or platform requirements that make everyday use less convenient.
Read the privacy policy, check the required hardware or account, and test whether you can pause the product during calls and other unsuitable tasks.
