How it works

1Record a short video of the horse trotting.
2Stride crops and analyzes the motion on-device.
3Get clear, objective metrics for head, withers, and pelvis symmetry.

Why on-device?

Privacy, speed, and reliability. Stride works anywhere — arenas, fields, clinics — even with no signal.

No uploads or waiting
Clinic-grade metrics
Designed by an equine vet

Objective symmetry

Head, withers, and pelvis vertical displacement with push-off and impact indices — left and right.

Advanced limb analysis

Cranial and caudal phase comparison, protraction and retraction angles with L/R difference. (Pro)

Timeline tracking

Select multiple analyses and visualize asymmetry evolution over time. Spot trends, track rehab progress.

Multi-export

Export multiple analyses at once as PDF reports, CSV data, or .stride bundles. Share with colleagues instantly.

Fast & offline

Typical analysis in under two minutes. No Internet required — ideal for barns, fields, and shows.

Secure backup

Automatic iCloud backup of all recordings and results. Restore your full database on any device.

What's new in Stride

📈 Timeline compare

Select 3 or more analyses to see head, withers, and pelvis asymmetry evolve over time — left and right on separate lines. Nerve block and flexion test markers appear directly on the charts.

🧬 Limb phase & angles

New advanced analysis: cranial/caudal phase comparison and protraction/retraction angle measurements for forelimbs and hindlimbs. See the left/right difference in percentage.

📦 Multi-select & batch export

Select unlimited analyses from the horse detail view. Export them all at once as PDF, CSV, or .stride files. Compare two side-by-side, or view a timeline for three or more.

💪 Rock-solid stability

Completely rewritten error handling. Database corruption recovery with iCloud restore. Analysis pauses and resumes automatically if you take a phone call or switch apps.

☁️ Full iCloud backup

Analysis results are now saved to iCloud alongside your videos. Rebuild your complete database on a new device without re-analyzing — all metrics, notes, and history are preserved.

📋 Enhanced PDF reports

PDF exports now include cranial/caudal phase charts and limb angle schematics. Timeline reports with L/R charts, severity zones, and vet markers.
