Spotter
An AI coach that actually watches you lift — every squat rep scored on depth and tempo, on-device.
Spotter is an AI lifting coach that films your squat and scores every rep on depth and tempo — on-device, no wearable. It auto-progresses your barbell weights across full-body 5×5, powerlifting, and hypertrophy programs, and coaches the whole session hands-free, with an Apple Watch companion.

The problem
Training alone, no one tells you if your squat hit depth or if the bar is moving right — and generic apps just log numbers or chat at you. You find out you grooved a bad pattern weeks later, and you never know when to add weight.
Why now
On-device pose models are finally good enough to score a lift in real time on a phone. Spotter turns that into a coach: it sees the rep, scores it, and moves the weight — no wearable, no trainer, no video ever leaving your phone.
Why I'm building this
A spotter is the person who watches your set and keeps you honest under the bar. Most lifters train alone and never get that. Spotter is that second set of eyes — it scores every rep and moves the weight for you — built camera-first so it works with the barbell you already own.

How it works
Set up your phone
Prop it upright, side-on, about 3 metres away so your whole body is in frame.
Lift
Spotter counts and scores each squat rep live, and speaks the coaching so you never look at the screen.
Earn the weight
Hit your reps with good depth and the coach adds load next session. Every lift climbs on its own.
Inside the app
Ready to lift
Today's session, streak, working weight — set by your coach.
Programs
StrongLifts 5×5, upper/lower hypertrophy, Barbell Burn — camera-scored.
Solid set
All five reps earned, depth held. Adding 2.5 kg next session.
Set cut short
Racked at 3 of 5 — this weight isn't earned yet. Hold it.
Workout complete
Average depth score, and whether the weight just earned a bump.
Warm-up ramp
Plate math to your working weight — warm-ups aren't scored.
Pro
Annual or monthly — start with seven days free.
What it does
Camera rep scoring
Films your squat side-on and scores every rep on depth and tempo, live — all on-device with Apple's Vision framework. No wearable, no upload.
The coach adds the weight
Hit your reps with good depth and the weight goes up next session; miss it and it holds or deloads. Every barbell lift — squat, bench, row, press, deadlift — progresses on its own.
Hands-free coaching
Counts your reps out loud, reads a coaching note between sets, and runs the rest timer — so you never touch the phone across the room. Warm-up ramp and plate math built in.
Apple Watch companion
Live rep count, last-rep score and rest on your wrist, with a tap to finish a set or skip rest — and a buzz on a bad rep.

1.0.1 — the post-launch audit
Camera-denied now shows a recovery screen and a log-by-hand option; the camera restarts after a call or a tab switch; the screen no longer sleeps mid-set. Rep counting now requires your hips to actually descend, and the weight only climbs when your average rep reaches parallel.
