AngleMotion turns the footage you already have into a permanent, shareable record of a player’s development — measured, corrected by you, and kept for as long as they play.
Sign in with Google and use every tool free for one hour — no card, no booking.
Every tool below exists because something in this timeline needed it. Scroll the season.
An illustrative timeline. The dates and readings are examples, not a real client’s record.
Shoulder, hip, knee, elbow — AngleMotion reads 13+ joint angles automatically and shows the numbers right on the frame. Compare a serve to a model, prove why a stroke breaks down, and back every note with a real measurement instead of a guess.
Every skeleton keypoint and every angle the AI detects is yours to move. Drag any point, correct any angle, trust the read. AI-fast for the 90%, coach-accurate for the 10% that matters — no black box you can’t touch.
Trust the AI for speed. Trust yourself for the truth.
Motion Layer turns a swing into a multi-position composite — as a still and as video. You choose the frames and the layers, so the trail shows the path you want the player to see. The demo that sells your coaching and the shareable that markets it.
Plus — it looks incredible.
Snapshot every phase of the stroke and replay it frame-by-frame in slow motion, side-by-side, with angle overlays. Then screen-record it with your webcam and mic to deliver a same-day coaching video your player can rewatch until it clicks.
Follow a player through a live match and log every point by hand, or let the Match Decoder read your SwingVision screenshots and derive the stats SwingVision doesn’t surface. Either way the match ends as data, not an impression.
Every player carries two documents — technical analysis and match analysis — plus a player database and progress tracking across the whole season. Rivals hand you a clip and stop. This is the client file, the deliverable, and the storefront in one place.
Every student’s technical story in one file — from first lesson to nationals.
Push the finished video straight to YouTube as unlisted and drop it into the player’s report. Nothing to store, nothing to pay for, no archive to run out of — an unlimited record your students keep and can rewatch years later.
The whole loop, start to finish. No step needs a second app.
Upload from your camera roll, pull from Google Drive, or paste a YouTube link. Nothing to install.
Step frame-by-frame to the moment that matters and snapshot it as a phase.
Run pose detection and AI Detect Angles, then correct any point the AI got wrong.
Pick your frames and layers and generate the Motion Layer still or video.
Capture screen, webcam and mic in one hub while you talk the player through it.
Publish to YouTube, drop everything into the player’s document, and share the link.
AngleMotion Academy is a growing library of eBooks, guides and drill breakdowns that teach the craft behind the tool — how to set up a shot, which phase of a stroke actually explains a fault, and how to turn a reading into something a player can act on. Coaches use it to sharpen their eye. Players and parents use it to analyse themselves properly instead of guessing.
Included with every plan.
AngleMotion was built by a working tennis coach to do the job he was already doing by hand. The reviews below are of Vin’s own coaching analysis — the practice the tool came out of. AngleMotion itself is new and hasn’t been reviewed yet.
Vin is truly an expert in biomechanics. He did an incredible job analyzing my son’s forehand, providing insights and analysis at a level I’ve never encountered before.
Vin gave me an amazing review about my swing… he saw areas of improvement my coach has never detected before… he really cares that I improve my game.
I’ve recently come across Vin’s content and I’ve been really impressed so far. Communication has been great and he has taken the time to answer all my questions.
Thank you Vin, your feedback was so, so useful — very professional, technical, and precise… your analysis is worth far more than the price… none went into this level of detail.
Vin’s expertise in biomechanics is remarkable. His thorough analysis of my son’s forehand revealed insights at a depth I’ve never experienced.
Outstanding tennis video analysis — clear, detailed and highly professional. A clear, structured breakdown of his stroke mechanics.
Great experience — great analysis, highly recommended.
All 6 reviews on Trustpilot are 5 stars — for Vin’s coaching analysis, not for the app.
