Dip Rep Counter
Stop counting in your head. Point your phone at yourself and every full-range dip counts itself — sets, reps, and PRs logged automatically while you train your triceps and chest, with shoulders assisting. Free, in your browser, no account needed.
▶ Start Counting FreeHOW TO DO A PROPER DIP
Setup Support yourself on parallel bars, side-on to the camera, arms straight.
- Lower until your shoulders dip below your elbows.
- Keep a slight forward lean.
- Press back up to lockout.
This is the same instruction sheet you’ll find on the ⓘ panel inside the app — with an animated demo next to it.
HANDS-FREE IN THREE STEPS
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.
The AI locks a 17-point skeleton on you
GoodReps measures your elbow angle (shoulder → elbow → wrist) in real time, entirely on your device. No wearables, no clickers. Parallel bars or a sturdy dip station.
Just work — the counter does the counting
A rep banks at the bottom (~75°) and re-arms when you return toward ~155°. Half reps don’t count, and after 3 clean reps it calibrates to your personal range of motion.
WHAT MAKES A REP COUNT
- Your elbow angle, live — from roughly 155° locked out down toward 75° at depth. Quarter-dips don't bank; real descents do.
- Your personal range of motion — after 3 clean reps the counter calibrates to your shoulders and build.
- Your depth on every rep — the form cue sets the standard: "Lower until shoulders past elbows."
COMMON DIP MISTAKES
Cutting the descent short
Tiny dips protect your ego, not your triceps. Lower until your shoulders pass your elbows — the camera checks from the side.
Diving too deep, too soon
Depth is earned. If your shoulders aren't ready, going way below parallel can pinch — build range gradually.
Elbows flaring wide
Wide elbows dump the load into your shoulders' worst angle. Keep them tracking back, close to your body.
Shrugging at the top
Finish tall with your shoulders pressed down away from your ears — the lockout is part of the rep.
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
What can I use for dips at home?
A dip station is ideal. Two sturdy, equal-height surfaces (like heavy chairs) can work if they truly don't move — stability comes first.
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.
