Guided Video Capture
An in-app filming guide shows good, too-far and off-angle examples so uploaded clips are actually analyzable before they're sent.

Posemetric - AI-Powered Equine Gait and Movement Analysis
Film a horse trotting with a phone, and Posemetric turns the clip into frame-by-frame joint angles, stance timing and an asymmetry report - the same data a lameness exam looks for, without a motion-capture lab.

The Challenge
Gait asymmetry is hard to track between vet visits.
Subtle lameness and gait asymmetry in horses are usually judged by eye, either by a vet during a scheduled visit or by an experienced owner who happens to notice a change. Objective motion-capture equipment exists, but it lives in clinics and research labs - not in a stable yard. Owners and trainers had no simple way to capture the same kind of joint-angle data themselves, on their own schedule, with a device they already carry.
Our Solution
A phone video in, a kinematic report out.
Posemetric EquiGait takes a short clip of a horse trotting - filmed side-on, following the in-app filming guide - and runs it through a computer vision pipeline that tracks anatomical landmarks frame by frame. The result is a set of joint-angle curves and a stance-by-stance breakdown the owner can read directly, or export and send to their vet. The same account and backend work identically on the web app and the companion Android app.
Key Features
What the platform does.
Automatic Landmark Tracking
The pipeline locates and tracks the horse's limb joints - carpus and tarsus on both sides - through every frame of the clip.
Frame-by-Frame Joint Angles
Angle curves for LF/RF carpus and LH/RH tarsus, plus stance detection (e.g. "RF+LH"), are plotted across the full clip.
Asymmetry Reporting
A dedicated report compares left and right sides to surface the kind of asymmetry a lameness exam looks for.
Studio Dashboard
Upload a clip, watch it process, and come back to browse every past analysis for a horse in one place.
One Account, Two Apps
Firebase Authentication is shared between the web app and the native Android app, so a single sign-in covers both.
Technical Approach
How it's built.
A React web client and a native Android app both talk to the same Cloudflare Worker API, so a clip uploaded from either one lands in the same account and the same analysis history. The web app is a static SPA, deployed automatically on every push to main.

Results
Where the project stands.
Live in production
Running today at app.posemetric.com, with continuous deployment from the main branch on every release.
Two clients, one backend
The web app and the Android app share one Cloudflare Worker API and one Firebase account, so analysis history stays in sync across devices.
Real pipeline output
Every screenshot on this page is genuine output from the analysis pipeline, not a mockup - people in the frame are blurred for privacy.
Filming Guide
What the pipeline needs from a clip.
Analysis quality depends on how the clip is filmed. The app guides owners toward a clean side-on trot pass and away from common mistakes.
Good: side-on, full body
The whole horse stays in frame through the trot pass, filmed roughly perpendicular to the direction of travel.
Avoid: filmed at an angle
An oblique camera angle distorts the joint geometry the pipeline is measuring.
Avoid: too far away
If the horse is too small in frame, landmark tracking loses the precision it needs.
