How it works

Three steps. Ten seconds of setup. Then just work normally.

1
Calibrate your baselineSit upright and press Start. Backtrack captures your shoulder and head position in 10 seconds.
2
Work normallyLeave the tab open. It still tracks when minimized. Feel free to switch tabs.
3
Get alerted when you slouchDrop 10% below baseline and you hear your chosen alert. Sit back up, it stops.

Based on research from the European Journal of Social Psychology, PMC, and psychophysiology studies on postural awareness.

What to expect, honestly

Most users see their average posture quality climb steadily. Here's the realistic timeline from our beta cohort.

Week 1
Awareness
You'll be surprised how often you slouch. The alerts feel constant at first. That's the point.
Month 1
Relief
Average slouch events per hour drop nearly in half. Your baseline score climbs 15-25%.
Day 60
Habit forms
Correcting becomes reflexive. The basal ganglia are taking over from conscious effort.
Day 90
Fixed
Upright is your default. Most users report less neck pain and noticeably better focus.

Why not a wearable?

Posture hardware is expensive, easy to forget, and works in one spot. Backtrack uses gear you already own.

Reviews from early users

Honest feedback from our beta cohort.

★★★★★

"I've tried two posture wearables and a $30 chair cushion. This is the first thing that actually stuck. The alerts are annoying enough to work but gentle enough that I don't hate the app."

"Neck pain I'd had for two years is mostly gone after six weeks. I'm not saying it was magic, I'm saying I finally became aware every single time I was slouching, which I never was before."

"The fact that it runs locally was the selling point for me. I work with client data all day and I'm not about to ship webcam frames to anyone's server. Looked under the hood, it really is on-device."

"Took me a day to find a sensitivity setting that worked for my desk setup, I'd leaned forward a little when calibrating. Once I re-did it, perfect. Support replied within an hour when I emailed."

"I hate apps that nag me. But this one only speaks up when I'm actually slouching, which is exactly the deal. My shoulders stopped aching around week 3."

Frequently asked questions

Does Backtrack record or upload my video?
No. Pose detection runs entirely in your browser using Google's MediaPipe. No video frames are ever sent to our servers. They literally cannot leave your computer. You can verify this yourself in your browser's Network tab.
Does it work on Mac, PC, and Linux?
Yes. Backtrack runs in any modern browser (Chrome, Safari, Firefox, or Edge) on Mac, Windows, or Linux. No install, no extension, no driver.
Can I use my laptop camera, or do I need a webcam?
Your built-in laptop camera works perfectly. A separate webcam at eye level can give slightly cleaner pose detection, but it's not required.
Does it work with multiple monitors or a standing desk?
Yes to both. As long as the camera can see your head and shoulders, Backtrack works. Many users mount their webcam on their primary monitor.
What if I wear glasses or have a beard?
Totally fine. Backtrack tracks head and shoulder position, not facial features. Glasses, beards, hats, and hairstyles don't affect detection.
How do I cancel?
Settings → Subscription → Cancel. One click. You'll keep access until the end of your billing period. No phone calls, no retention runaround.
Do you offer refunds?
Yes. 7-day money-back guarantee on all plans, no questions asked. Email us at support@back-track.app and we'll process it within 24 hours.
Can I export my data?
Yes, anytime. Settings → Data & Privacy → Export. You'll get a JSON file with every session, streak, and setting.
Is 90 days actually how long it takes to build a habit?
The peer-reviewed Lally et al. (2010) study found habit formation ranges from 18 to 254 days, with a median of 66. We picked 90 as a realistic target for a physical habit involving postural muscles, more conservative than the average, but well under the max.
Can multiple people use one account?
Each account is for one person because your posture baseline and streak are personal. Team/family plans are on the roadmap. Email us if you're interested.

About Backtrack

Why one frustrated founder built a software-only posture fix.

The short version

Backtrack was built by Sean Vierthin 2026 after two years of on-and-off neck pain and a $70 wearable that lived in a drawer. The premise is simple: you already own a webcam, and modern on-device AI is good enough to watch your posture without sending a single frame anywhere. So that's what we did.

Our bet

Most posture products are either hardware you forget to wear, or coaching apps that guilt you. Neither works because the hardest part of fixing posture is noticing the moment you slouch. Backtrack's entire job is to reliably notice, gently alert, and get out of the way for as many workdays as it takes for upright to become your default.

Privacy first, because anything less is unserious

We made a deliberate architectural choice: run the model in your browser. It's slightly harder to build than a cloud pipeline, but it means we never have to promise not to look at your video, because we literally can't. We don't want that liability, and neither do you.

What's next

We're shipping Apple Health + Google Fit integrations, a mobile companion app for reviewing stats, and team plans for remote-first companies. Every feature we ship preserves the on-device guarantee.
