StopSlouching vs Upright Go 2.

We make one of these (StopSlouching). We've also worn the Upright Go 2 for a couple of weeks for this comparison. They're both real tools that solve overlapping but distinct problems.

The right choice depends almost entirely on whereyou slouch. Skip to the “how to pick” section below if you just want the recommendation.

How they actually work

StopSlouchinguses your laptop's webcam to detect pose landmarks (head position, shoulder evenness, upright score) about ten times per second. After a 5-second calibration to your seated baseline, it scores you continuously and pings you when you drift below threshold for a configurable sustain time. All of this happens locally in the browser — no video is uploaded.

Upright Go 2 is a small accelerometer/gyroscope module that adheres to your upper back with a reusable hypoallergenic adhesive. It senses upper-back angle relative to a calibrated baseline and vibrates when you slouch. It connects to a phone app that logs trends.

Both use the same underlying principle: real-time biofeedback — an immediate cue when posture degrades — which is what the physical therapy literature consistently shows outperforms time-based reminders. The difference is what they can sense and where they work.

Side by side

What StopSlouching does better

• No hardware to remember.The single biggest reason wearables fail long-term is people stop wearing them. With a webcam coach, you don't have to remember anything — it's active the moment you open your laptop.
• Sensitivity to forward-head posture.Upright Go measures upper-back angle. StopSlouching also measures head position. The classic “text neck” pattern is forward-head with relatively neutral upper back — Upright can miss this; the webcam catches it.
• Free to try. A full hour of free detection costs nothing. You find out within five minutes whether the approach works for your specific desk setup before paying anything.
• Works on multiple machines. Same account, same baseline, works at the office and at home.

What Upright Go 2 does better

• Mobility.The webcam can't see you when you stand up, take a meeting in another room, or work from a couch with your laptop closed. Upright Go follows you.
• Tactile feedback. A vibration on your back is harder to ignore than a screen notification. For people whose slouch is deeply ingrained, the physical signal is more effective.
• No CPU usage. Webcam pose detection uses ~3–6% CPU. Negligible on modern machines, but noticeable on older laptops or during heavy work.
• Mature mobile app. Their iOS/Android app for tracking trends has a few more years of polish than ours.

Price math over a year

Assuming both used 5 days a week:

• Upright Go 2: $80 device + ~$60/year in adhesive refills = ~$140 year one, ~$60/year after.
• StopSlouching free plan: 60 minutes of free detection, lifetime. $0/year.
• StopSlouching subscription: Unlimited detection + history. See pricing on the app page.

If you're shopping on price alone, the free plan of StopSlouching is the cheapest way to find out whether real-time posture feedback actually changes your habits. If it does, you can decide whether to upgrade or buy hardware. If it doesn't, you haven't spent anything.

How to pick (decision tree)

1. Q: Is more than 70% of your slouching at a desk?
   Yes → StopSlouching. Save the $140.
   No → Continue.
2. Q: Do you take a lot of meetings standing or walking?
   Yes → Upright Go 2.
   No → Continue.
3. Q: Do you care most about head-forward posture (vs upper-back rounding)?
   Yes → StopSlouching (it measures the head angle Upright misses).
   No → Either. Lean wearable if you'll remember to wear it; webcam if you won't.
