Deadlift Rep Counter
Skip the mental math. Point your phone at yourself and every full-range deadlift counts itself — sets, reps, and PRs logged while you train your hamstrings, glutes and back, with core and forearms assisting. Free in your browser today; coming to Google Play and the App Store.

LIVEHOW TO DO A PROPER DEADLIFT
Setup Stand side-on to the camera, the weight over your mid-foot, feet hip-width.
- Hinge at the hips with a flat back and grip the weight.
- Drive through your heels and stand tall — hips and shoulders rise together.
- Lower with control, keeping your back flat and the weight close.
Same sheet as the ⓘ panel in the app — animated demo included.
HANDS-FREE IN THREE STEPS
Prop your phone and get in frame
Phone at roughly torso height, set up side-on to the camera. A quick camera test checks lighting, distance, and angle before you start.
The camera locks a 17-point skeleton on you
GOODREPS measures your hip angle (shoulder → hip → knee) on-device — no wearables, no clickers. A barbell, dumbbells, or a kettlebell over mid-foot — log the weight, track PRs.
Just work — the counter does the counting
A rep banks at the bottom (~95°) and re-arms near ~160°. Half reps don’t count; after 3 clean reps it calibrates to your range.
WHAT MAKES A REP COUNT
- Your hip angle, live — from roughly 160° standing tall down toward 95° in the hinge. The rep banks on a full stand-up, not a half-lockout.
- Your personal range of motion — after 3 clean reps the counter calibrates to your build and hinge depth, so it stays honest without being unfair.
- Your hinge shape from the side — the form cue that matters most is the one the app leads with: "Flat back, drive hips."
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.
PRIVATE BY DESIGN
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.
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.
