How it works
From clip to coaching in seconds.
Prop up your phone. Film your skill. Stunt Lab analyses the movement, finds what matters, and turns it into your next focus.
2
Coach reads every frame
Stunt Lab tracks your movement through the whole skill, scores it out of 100, and shows what made the score: take-off, angles, rotation, shape, landing.
3
Know what to work on next
Your analysis becomes your next session: the progression, drills and conditioning to close the gap, in a focused 15 minutes.
Why it works
Stop guessing what's holding you back.
Most athletes don't plateau from lack of effort. They plateau because it's hard to see exactly what's holding a skill back.
Get the skill sooner
See what's holding the skill back. Stop repeating the same rep with the same flaw. Know what's happening in your skill, what matters most, and what to work on next.
Train anywhere. Get the details.
Whether you're at the gym or at home, film a rep, see exactly what's happening, and leave with a clear focus for your next session.
Know where the rep is at
Every clip ends with a clear verdict: Competition clean, Close or Building. A simple snapshot of the rep you filmed, so you know exactly where that attempt stands.
Feedback you can actually use
One clear cue, two drills and two conditioning exercises, all built into a focused 15-minute session around what your skill needs next.
The score
What decides whether it's your skill?
Every clip is measured frame by frame: flight time, block height, joint angles, how far you travel on the landing. The number is just the summary. The breakdown is the coaching, and what it scores depends on the skill.
Take-offDo your arms finish before your knees start? Late sets are the number-one reason tucks undercut.
HeightHow much air the skill actually gets, measured from your hips, not the feeling of it.
RotationHow fast you come around, and whether you're pulling or hoping.
ShapeWhether the shape you think you're holding is the one you're holding.
TwistingWhen the twist starts, how square it finishes, and whether it cost you height. Scored on twisting skills.
LandingDrift, absorption, control. The part judges and coaches notice first.
74 · You're close. Keep drilling.
Scores keep sharpening as Coach learns the way you perform each skill.

Questions
Good to know before you join.
What is Stunt Lab?
A training app for tumblers, made with the coaches at Stunt Culture. You film a skill and it shows you how clean the rep was, what held it back, and what to train next. It’s built for the hours between coaching sessions, when nobody is watching your reps.
How does it work?
Prop your phone up side on and film one skill, 20 seconds or less. Stunt Lab follows your body from take-off to landing and gives the rep a score out of 100, with a breakdown of what earned it. Then it picks the one thing to fix first and the drills that fix it.
Does my video leave my phone?
No. Your video stays on your phone, and the analysis happens there too. Nothing is uploaded unless you choose to send us a video.
Does it replace my coach?
No, and it isn’t meant to. Your coach decides what you’re ready to throw. Stunt Lab is for the work in between: it shows you what your last rep really looked like, so you walk back into the gym with something specific to work on.
Which skills can it score?
It starts with the foundations and builds up: handstands and cartwheels, through handsprings, to standing tucks and layouts. A skill is only switched on once its scoring holds up against a coach’s eye, so new ones arrive in stages.
What does it cost?
Stunt Lab is a paid membership that starts with a free trial, so you can try it on your own skills first. Plans and prices are shown in the app, in your currency, before you commit to anything.
Is it on iPhone and Android?
iPhone only for now. There is no Android version yet.
How do the founding places work?
The first 100 members are our founding members. They come in as four groups of 25, and each group has its own badge: Founding 25, Founding 50, Founding 75 and Founding 100. Places are given in the order they’re earned, so the sooner you earn yours, the earlier your group. The badge stays on your profile for good.
How do I get a founding place?
Bring three friends. You get your own link as soon as you join, and it’s in your welcome email too. When three friends have joined the waitlist with it and confirmed their email, your place is secured, while places remain. That is the only rule.
Is a founding place free?
No. A founding place gets you in first and gives you the badge. The membership itself costs the same for everyone.
What if I don’t bring three friends?
You stay on the waitlist, and we’ll email you when more places open after the founding groups.
What is a Lab Partner?
Lab Partners help us tune the scoring. They get early access, film their skills and send us the videos, and a coach checks each one against the score the app gave. They come in separately from the 100 founding places and have their own badge in the app. If you’re under 18, a parent signs you up. Join on the Lab Partners page.
What is an Ambassador?
Ambassadors are creators we pay to make content with Stunt Lab, and they have their own badge in the app. How it works, and how to apply, is on the Ambassadors page.
I’m under 18. Can I join?
Yes. There is no minimum age. Check with a parent before you join the waitlist or share your link, and a parent approves the membership when you start.
