Stop logging.
Just lift.
A headband that watches your set and logs the exercise, your reps, and the weight on the bar — automatically. You type nothing.
Built by a solo founder who got tired of typing reps into an app mid-set.
The old way
Phone out. Gloves off. Thumb-typing 3×8 @ 80 kg between sets.
Every rep you log by hand is a rep you stopped to remember. The rhythm breaks, the numbers get fudged, half of them never make it in. There's a better way to remember what you did.
Meet IronPal One band.
One band.
Everything logged.
Moisture-wicking fabric, an 8 mm flush camera, a single teal LED. No screen, nothing to clip to the bar. Forgettable on your head — that's the point.
- Works on free weights and machines
- No equipment instrumentation, no per-machine setup
- First-person view — it sees what you see
In the app
Three numbers, logged for you.

Recognition
It knows what you’re doing.
A fine-tuned motion model running on your device, plus the camera, identifies the movement automatically — and it learns from your own sets. No scrolling a menu to find “triceps cable pushdown” before every set.

Counting
Every rep. Even the grindy ones.
Sensor fusion — motion and vision together — counts the set, including the slow heavy reps that wrist trackers quietly miss.

The hard part
It reads the weight off the bar.
Straight off the stack or the plates, from your point of view — no proprietary equipment, no QR codes, no typing. The part no one has shipped, and what we’re building.

Form It sees the rep.
It sees the rep.
So it can judge the rep.
From a first-person view, the same camera that counts your reps can watch how they look — squat depth, back angle, whether the knee tracks the foot. This is what the interface will show.
Like reading the weight, it's being built rather than shipped: reps and exercise recognition come first.
- Depth to parallel, rep by rep
- Back angle from vertical
- Knee tracking over the foot

The full picture
Everything it does, while you do nothing.
Sensor-fusion reps
Motion and vision together — counts the heavy reps too.
Reads any weight
Off the bar or the stack. No proprietary plates.
Learns your lifts
The model trains on your own confirmed sets — recognition sharpens the more you lift.
Free weights + machines
No per-machine calibration, no equipment instrumentation.
Zero taps, ever
Just train. The log fills itself in, set after set.
How it works
Wear it. Lift. It's logged.

Wear it
Slip on the band like any other. Camera and motion sensors wake up with you.

It's logged
Exercise, reps, and weight land in your log automatically. Nothing to type.
Why nobody else does this
The whole market makes you type the weight.
| Device | Picks the exercise? | Counts reps? | Reads the weight? |
|---|---|---|---|
| Wrist trackers (Garmin / WHOOP) | auto, often wrong | unreliable / none | ✕ estimates from body mass |
| Bar IMU sensors (Enode / GymAware) | manual / learned | drops heavy reps | ✕ manual entry |
| Camera appliances (Tempo) | in-class only | yes, in class | ✕ only their own plates |
| IronPal | automatic | sensor-fusion | ✓ any free weight |
Automatic free-weight reading is an open gap across the entire market. It's the hard problem we're building — and the reason IronPal exists.
Who's behind it
One founder, building this in the open.
I'm a solo founder, not a brand. IronPal started because I was sick of breaking every set to thumb numbers into an app — and because when I looked, nobody could actually read the weight off the bar. I'm building that, on camera, in public. Back the person, watch the progress.
Privacy
A camera on your head — handled honestly.
Your reps and exercise are detected right on the band, offline — by a fine-tuned motion model that runs on your device, so nothing about your movement leaves it. To read the weight, a single frame is sent securely, processed in seconds, and deleted immediately. We don't store your footage. We'll tell you exactly what's happening — no vague promises.

FAQ
Straight answers.
Does it really read the weight?
Reading arbitrary free weights from a first-person camera is the hard problem we're building — no shipping product does it today. It's our core bet, not a finished, guaranteed feature yet. Reps and exercise recognition are further along.
Does IronPal use AI?
Yes — a fine-tuned motion model that runs on your device, not in the cloud. It learns from your own confirmed sets, so exercise recognition and rep counting get sharper the more you lift. Only weight-reading sends anything off-device: a single frame, processed in seconds and deleted.
Does it correct my form?
Not yet. Form tracking — squat depth, back angle, whether the knee tracks the foot — is the next capability after reps and weight, and the screen you see on this page is the interface concept for it. Like weight-reading, it's being built rather than shipped.
Does it work on machines and cables?
That's the goal — free weights and machines, with no equipment instrumentation and no per-machine calibration. We're validating exercise by exercise.
What gets sent to the cloud, and what's kept?
Reps and exercise are detected on the band, offline. Only weight-reading sends a single frame off-device; it's processed in seconds and deleted immediately. Your footage isn't stored.
When does it ship?
We're pre-launch. Reserve your spot and you'll be first to hear the date — and first in line at the early-bird price.
What does reserving commit me to?
Nothing today. It locks your early-bird price and a 48-hour head start. You decide whether to back when we launch.
