About MoctaX - Sports Biomechanics
Film a piece. Get it graded, stroke by stroke. MotionX turns the phone already in your kit bag into a technique lab. Point it at the erg, the boat or the road and it reads your body position frame by frame — no sensors, no markers, no special camera. You get back a score, and more usefully, the reason for the score: which part of the stroke cost you the points, and what to change. BUILT FOR ROWING • Catch and finish angles, measured rather than eyeballed • Stroke rate and rate spread — is the rhythm metronomic, or wandering? • Consistency, Efficiency and Durability scored as separate pillars • Your best and median stroke, and whether technique held to the end • A capture wizard and trimmer, so a usable clip takes one attempt CONCEPT2 PM5 OVER BLUETOOTH Pair the monitor and record erg pieces live. Splits, rate, distance and heart rate are logged next to the video, and you can connect your Concept2 account so the workouts already in your logbook come across too. AN AI COACH THAT HAS READ YOUR SESSION Ask about any piece and the answer comes from your own numbers, not from generic advice — and it points at the strokes it is talking about. On the erg it can talk to you while you row. FOR CLUBS AND CREWS Join your squad with an invite code. Coaches review sessions, leave comments in their own voice, publish a report, and run a shared film room the whole squad can watch. Athletes get a notification the moment feedback lands. ALSO WORKS FOR Golf, running and volleyball. Swing and gait analysis, joint angles through the movement, and side-by-side comparison against a reference clip. FOUR WAYS TO ANALYSE • Rowing — a single clip, graded • Image vs image — two static positions compared • Video vs video — two sequences aligned and scored • Realtime — live skeleton and scoring straight from the camera BUILT TO BE TRUSTED Every number is traceable to the frame it came from. When a clip is too dark, too far away or too short to grade honestly, the app says so instead of inventing a result. Your history stays yours: past pieces, PDF reports, a training log and a streak, all in one place. English and 简体中文, switchable in Settings without restarting. — SUBSCRIPTIONS MotionX is free to use, with daily limits on analyses and AI coaching.

What’s new
Version 1.4.3 · Updated October 10, 2026
What's New in 1.4.3 A big one. Race your crew live from anywhere, start a training plan in one tap, and see every stroke the moment you stop. Row together, live Open a room, share the code, and race friends or your whole crew on your own PM5s, wherever each of you is. Start together on a countdown or go when you're ready, follow everyone's split live, and watch the boats move down one course. Club rooms are open to your whole team. Free for everyone. Plans, ready in a tap Train now has three clear views: Week, Plans and Erg. Start a ready-made plan (2k prep, Aerobic base, Head race prep, Race-week taper and more), or let the AI coach build one around your goals. Keep using the app while it's built; we'll tell you when it's ready. A stricter, sharper stroke score We rebuilt the erg stroke score on real PM5 force curves. Every stroke is graded on catch, peak, fullness, finish and smoothness, and the one fix that matters most comes first, with a cue and a drill. It's stricter than before, so expect lower numbers that mean more. Every stroke, the moment you stop Your full analysis opens as soon as the piece ends: scrub stroke by stroke through pace, rate and force curve in sync. Just a warm-up? Discard it without saving. Mid-piece, turn your phone sideways for a full-width curve and bigger numbers. Share with your coach Send any session privately by link, AirDrop or QR code. Make it view-only or let them save it, set an expiry, and switch it off anytime. Sessions shared with you land in "Shared with me". Run your club from your phone Coaches can build and assign training plans, set lineups, check the squad's erg board and get an AI read of the week, all on iPhone. Boat sync now asks you to tap your crew first, so no seat goes to a rower from another boat. Polish & fixes • See whether your analysis is queued or processing; we'll notify you when it's done • Exported videos open straight in the share sheet • Erg pieces that fail to sync stay on your phone, with Retry and Export • Thumbnails show a real frame from your session • A cleaner, darker look for sheets and menus • Fixed Training plans in Settings showing an error • Fixed a crash when opening the app from a notification
