Deadlift Rep Counter

Stop counting in your head. Point your phone at yourself and every full-range deadlift counts itself — sets, reps, and PRs logged automatically while you train your hamstrings, glutes and back, with core and forearms assisting. Free, in your browser, no account needed.

HOW TO DO A PROPER DEADLIFT

Setup  Stand side-on to the camera, the weight over your mid-foot, feet hip-width.

  1. Hinge at the hips with a flat back and grip the weight.
  2. Drive through your heels and stand tall — hips and shoulders rise together.
  3. Lower with control, keeping your back flat and the weight close.
Form cue: Flat back, drive hips

This is the same instruction sheet you’ll find on the ⓘ panel inside the app — with an animated demo next to it.

How The Counting Works

HANDS-FREE IN THREE STEPS

1

Prop your phone and get in frame

Set your phone at roughly torso height and set up side-on to the camera. The built-in camera test confirms your lighting, distance, and angle with live green checks before you start.

2

The AI locks a 17-point skeleton on you

GoodReps measures your hip angle (shoulder → hip → knee) in real time, entirely on your device. No wearables, no clickers. A barbell, dumbbells, or a kettlebell over mid-foot — log the weight, track PRs.

3

Just work — the counter does the counting

A rep banks at the bottom (~95°) and re-arms when you return toward ~160°. Half reps don’t count, and after 3 clean reps it calibrates to your personal range of motion.

Under The Hood

WHAT MAKES A REP COUNT

Form Still Matters

COMMON DEADLIFT MISTAKES

Rounding your lower back

The cardinal deadlift sin. Brace hard before the pull, chest proud, and think "long spine" — if your back rounds to move the weight, the weight is too heavy today.

Squatting the pull

A deadlift is a hinge, not a squat. Push your hips back and let them ride higher than a squat would — your hamstrings should feel the stretch before the bar moves.

Bar drifting away from you

Every inch the weight drifts forward multiplies the load on your spine. Keep it dragging up your legs like a zipper.

Soft lockout

Finishing bent over leaves the rep incomplete. Stand all the way up — hips through, shoulders back, no lean-back needed.

Your Data

PRIVATE BY DESIGN

Rep counting runs entirely on your device — your camera feed is never uploaded.

Pose detection runs in your browser via TensorFlow.js. Camera frames are analyzed in real time and immediately discarded — nothing is recorded, nothing leaves your phone, and we never see them. Sign-in is optional; skip it and everything stays local.

FAQ

QUESTIONS, ANSWERED

Do I need a barbell to check my deadlift form?

No — a single kettlebell or a pair of dumbbells over mid-foot works the same hinge. Log whatever you pull and the app tracks your PRs.

Does it work in a home gym or low light?

Run the built-in camera test first — it checks your lighting, distance, and angle with live green checks before you start. If a rep still slips through, manual counting is always one tap away.

Is my camera feed uploaded anywhere?

No. Pose detection runs entirely on your phone, in your browser. Frames are analyzed in real time and immediately discarded — nothing is recorded, nothing is uploaded.
