StrokeVision watches your swing the way a coach would — from your feet all the way up to your follow-through — finds the one or two things holding you back today, and shows you exactly how to fix them. In plain English, with the why behind every tip.
You're making contact a touch late.
Your elbow stayed slightly bent at contact — often a sign the ball got behind you. Try meeting it a half-step earlier, out in front of your hip.
Built on the same things real tennis coaches teach
Lessons cost $60–150 each. Clinics happen once a week, if you're lucky. So most of your court time reinforces whatever habits you already have — with no one watching, and no feedback until the next lesson days away.
Filming yourself doesn't close the gap. You watch the clip once, can't tell what your body is actually doing, and shelve it. The distance between “I have video of my swing” and “I know what to fix and how” is exactly the gap a coach fills — and exactly what StrokeVision was built to fill, on every practice video, instantly.
A full coaching session — record to recommendation — in under a minute.
Set your phone down at the side of the court, full body in frame. Record live or pick a clip from your camera roll. Slow-mo welcome.
StrokeVision follows your whole body as you swing — your feet, knees, hips, shoulders, arm, and the moment you hit the ball — and checks 21 different things that go into a great shot.
No confusing numbers to figure out — just clear, simple advice: what to work on, why it's happening, and exactly what to try next. Plus a pro's swing to compare against.
Every session feeds a progression timeline. See what's actually changing — not a guess, a measurement — and watch the habit you've been working on improve.
Power and control come from the ground up — your feet, knees, hips, shoulders, and arm all working together. A small mistake down low shows up as a bad shot up top. StrokeVision watches all of it, so the advice you get fixes the real cause — not just what you happened to notice.
A few clear tips after every session, in plain English — what to work on, why it's happening on court, and exactly what to try. Built on real coaching know-how, not random advice from a chatbot.
From how your feet are planted to how high you finish your swing — the same details a real coach looks for, checked every single time.
Layer your skeleton over Federer, Sinner or Djokovic. A reference to learn from — never a “copy this exactly” instruction.
Metric trends, session over session. Watch the thing you've been working on actually move.
If your video is a little blurry or shot from a tough angle, StrokeVision tells you instead of making something up — just like a real coach would say "I couldn't quite see that, film it again." You always know how sure it is.
Lay your swing right on top of a pro's and watch them side by side — so you can actually see the difference, not just read about it.
Nadal & Alcaraz coming next.
“I've filmed myself for years and never knew what I was looking at. The first session told me my contact point was late — something three lessons never named clearly.”
“It doesn't bury me in numbers. It picks the one thing, tells me why, and I go work on it. That's exactly what my coach does — but I get it every single practice.”
“Overlaying my forehand on Federer's was a wake-up call. I could finally see how little I was rotating my hips. My ball is heavier now.”

One private lesson is ~$60–150. A year of StrokeVision is less than one.
87 million tennis players worldwide — and far too few coaches, with lessons that cost a fortune. StrokeVision turns the phone every player already films themselves with into the coaching they could never afford to get this often.
Around 87 million players worldwide, roughly 24 million in the US. Most everyday players practice far more than they can afford to get coached — and many already film themselves. That's a ready-made audience for coaching delivered through an app.
Every tip is backed by real coaching principles that experts have checked — not made-up advice. And because the app is honest when it isn't sure, players trust it in a way they won't trust apps that fake confidence. It's also built to handle every kind of shot, not just one.
$9.99/month or $79.99/year — next to nothing against a $60–150 lesson. A free trial turns curiosity into a habit, and founder pricing rewards early believers. Each swing costs us almost nothing to analyze, so most of the revenue is profit.
The app is live and testable today. The whole experience works end to end — record a swing, get it analyzed, see your coaching, compare to a pro, and track your progress — with payments and feedback already built in.
We start with the forehand; the backhand, serve, volley and the rest follow. After that: the option to have a real human coach review your swing, an add-on for serious players, and other racquet sports like pickleball, padel and badminton.
We're raising to accelerate multi-stroke coverage and the external beta.
Request the deckWe're starting with the forehand, fully coached. But the app was designed from day one to handle every shot in the game.
21 signals, validated coaching KB, pro overlay.
Each one coached just as carefully as the forehand.

Get a real coach to check your swing on demand. Then pickleball, padel and badminton.
Right now it fully coaches the forehand (filmed from the side). The backhand, serve, volley, overhead and more are on the way — each one coached just as carefully. We'd rather get one shot truly right than half-coach all of them.
Set your phone at the side of the court, roughly 10–15 feet away, with your full body in frame. Side-on, well-lit, slow-motion clips give the sharpest coaching. If the angle or lighting limits what we can see, the app tells you instead of guessing.
It's the technique feedback loop you'd get from a coach — on every practice video, instantly. It focuses on stroke technique only. It does not give medical, injury, or equipment advice, and it isn't a substitute for in-person coaching on strategy, mental game, or movement. Think of it as your coach's eye, every session.
No. Pros are a reference, not a prescription. Bodies and styles differ; laying your swing over theirs helps you see how your body moves, not copy a number.
Five full coaching sessions free, no card. Then $9.99/month or $79.99/year. The first 100 subscribers lock in founder pricing of $4.99/$39.99 forever.
