Ski technique analysis built for cross-country skiers
Everything you need to understand and improve your skate and classic technique, on snow and on rollerskis.
Skate and classic technique classification
Automatic detection of your skating or classic technique, with efficiency score, cadence (strokes per minute) and an overall technique rating for each.
Instant individual coaching
Prioritized cues based on your body and your session, each with your current value and an optimal target range. Not generic tips, biomechanics-backed feedback.
Rollerski technique analysis
The same ski movement analysis works on asphalt. Keep refining skate and classic technique through the dryland season and see how it transfers to snow.
Injury prevention
Detect left/right asymmetries and fatigue-driven form breakdown before they turn into back pain or knee problems.
Progress tracking
Watch your technique score, cycle efficiency and cadence improve across the season. Data-driven proof that your ski training is working.
From ski video to coaching in three steps
A smartphone is all you need. No sensors, no lab.
1
Record your session
Film your skiing or rollerskiing with a smartphone. Position the camera for a clear view of your whole body while you ski.
2
AI technique analysis
The engine identifies key body points and tracks your movement frame by frame: weight transfer, pole timing, body position, symmetry and joint dynamics.
3
Get individual feedback
Technique type, efficiency percentage, cadence and an overall score, plus prioritized coaching tips with current values and target ranges.
Six dimensions of your skiing technique, scored
After every session PerfoScan.ai analyzes your technique and delivers individual coaching with specific metrics and target ranges. A sample skate session:

Coaching feedback
Legs too stiff – flex knees 100-120 then extend to 160-170
Current 11.4 → Target 60.0–80.0
Press shins forward against boot cuffs
Current 9.4 → Target 70.0–80.0
Stride rhythm is inconsistent – find your tempo
Current 51.3 → Target 0.0–8.0
Too much vertical bounce – wasted energy
Current 23.7 → Target 0.0–0.1
PerfoScan.ai's adaptive coaching engine evaluates six key dimensions of cross-country ski technique: weight transfer, cycle efficiency, body position, symmetry, joint dynamics and upper body mechanics. Each metric is scored and weighted into one technique rating, then turned into prioritized coaching, from critical form corrections to fine-tuning, with your current values and optimal target ranges. Like a professional ski coach analyzing every stride, on snow or on rollerskis.
Ski technique analysis, explained
Straight answers about AI ski coaching, skate and classic technique, rollerski training and pricing.
What is PerfoScan.ai?
PerfoScan.ai is an AI ski coach for cross-country skiers and rollerskiers. Upload a video of your skate or classic technique and the app analyzes your movement: weight transfer, cycle efficiency, body position, symmetry and joint dynamics. You get instant, individual coaching with target ranges. The app is free on iOS and Android and also available on the web.
Which skiing techniques does PerfoScan.ai analyze?
Cross-country skate skiing and classic skiing, on snow and on rollerskis. The same ski movement analysis engine is used for both, so dryland rollerski sessions and winter skiing sessions are scored on the same scale.
How does ski video analysis work?
Film yourself with a smartphone. The app detects key body points frame by frame, classifies your technique and measures how you move. You get technique type, efficiency percentage, cadence and an overall score within seconds. No sensors are required.
Does PerfoScan.ai work for rollerski training?
Yes. Rollerski technique analysis is a core use case. The same metrics and coaching apply on asphalt, so you can build skate and classic technique year-round and check that it transfers to snow.
Is PerfoScan.ai for beginners or competitive skiers?
Both. Beginners get a few prioritized cues to build safe, efficient technique from the first session. Competitive skiers and their coaches get detailed biomechanical metrics, asymmetry detection and long-term trend tracking that normally requires a sports-science lab.
How is PerfoScan.ai different from Strava or Garmin Connect?
Those platforms record what you did: distance, pace, heart rate, training load. PerfoScan.ai analyzes how you moved while doing it and coaches you to ski better. Keep your training log and add a coach that sees your technique.
Can PerfoScan.ai help prevent skiing injuries?
Many overuse problems in skiing start as small left/right asymmetries or fatigue-driven form breakdown that skiers cannot feel. PerfoScan.ai flags these patterns as they develop so you can adjust load or technique early. It is a training tool, not a medical device.
Is PerfoScan.ai free?
Yes. The PerfoScan.ai app is free to download on the App Store and Google Play and includes core ski technique analysis and coaching. Advanced features may be offered as optional upgrades.
