Everything you need to understand and improve your movement — across every endurance sport.
Your movement data is processed in under 2 seconds, delivering coaching while you train — not hours after.
All sensor streams fuse into a 3D biomechanical model — your digital twin mirrors joint angles, forces, and body position.
Personalized feedback based on YOUR body and YOUR conditions. Not generic tips — biomechanics-backed insights.
Detect asymmetries and fatigue patterns that lead to injury — before they become a problem.
Watch your form score improve over weeks and months. Data-driven proof that your training is working.
Connects to 200+ devices: Garmin, Apple Watch, Polar, WHOOP, power meters, cameras, and more.
From sensors on your body to coaching in your ear — in three steps.
Link your wearables, phone sensors, cameras, and BLE/ANT+ devices. PerfoScan connects to every sensor type.
All sensor streams fuse into a real-time 3D biomechanical model — your digital twin with scientific precision.
Your personal coach analyzes the twin in real-time and gives individual, actionable feedback for your sport.
One platform. All sports. Sport-specific biomechanics with adaptive, individual coaching.
"Your double-pole glide phase is 15% shorter than optimal. Focus on complete weight transfer before the next pole plant."
"Your ground contact time increased 12ms after km 8, correlating with a 3° pelvic drop on the right side. Single-leg glute bridges 3x/week will fix this."
"Your aero position degrades 4cm after 60 minutes. Core fatigue is the likely cause — add 10-min planks to your routine."
"You're braking too late into corners, losing 2.3 seconds per lap. Start braking 3 meters earlier."
"Your downhill efficiency drops 30% after 40km. Shorter, quicker steps will reduce impact force by 22%."
Plus: Hiking, Ski Touring, Race Walking, Snowshoeing, Gravel, Indoor Cycling, and more coming soon.

Straight answers about AI biomechanics coaching, sensors, sports and pricing.
PerfoScan.ai is an AI-powered personal biomechanics coach for endurance athletes. It connects to the sensors you already own, builds a real-time digital twin of your movement, and gives instant, individual coaching for running, cross-country skiing, cycling, swimming, triathlon, trail running and rowing. It is available as a free iOS and Android app.
Most endurance performance is lost through inefficient technique, not lack of fitness. PerfoScan.ai measures how you actually move — cadence, ground contact, joint angles, left/right symmetry, pole or stroke timing — and tells you in under two seconds what to change. Better movement economy means more speed at the same heart rate, less wasted energy and fewer overuse injuries.
Running, cross-country skiing (classic and skate), cycling, mountain biking, swimming, triathlon, trail running and rowing. The same digital-twin engine adapts to each sport's movement pattern, so multisport athletes get one coach for every discipline.
A smartphone is enough to start. For deeper analysis PerfoScan.ai connects to 200+ devices, including Garmin, Apple Watch, Polar, Suunto, WHOOP, Coros, power meters, foot pods, IMU motion sensors and cameras. Data from all of them is fused into one biomechanical model.
Both. Beginners get simple, prioritised cues to build safe and efficient technique from day one. Competitive and elite athletes and their coaches get detailed biomechanical metrics, asymmetry detection and long-term trend tracking that normally requires a sports-science lab.
Those platforms record what you did — distance, pace, heart rate, training load. PerfoScan.ai analyses how you moved while doing it and coaches you to move better. It complements your existing training log rather than replacing it: keep your plan, add a coach that sees your technique.
Yes. Many overuse injuries start as small left/right asymmetries or fatigue-driven form breakdown that athletes cannot feel. PerfoScan.ai detects these patterns as they develop and flags them before they become pain, so you can adjust load or technique early. It is a training tool, not a medical device.
Yes. The PerfoScan.ai app is free to download on the App Store and Google Play and includes core movement analysis and coaching. Advanced features may be offered as optional upgrades.
