Built on Scientific Evidence
Every metric and recommendation is grounded in peer-reviewed research
Peak-30 Cadence Research
Based on UK Biobank study showing ≥100 spm for 30 minutes independently predicts 40-50% lower mortality risk (Del Pozo-Cruz et al., JAMA 2022)
Moderate Intensity Threshold
CADENCE-Adults study (Tudor-Locke et al., 2019) established 100 steps/minute = 3 METs with 86% sensitivity, 89.6% specificity—the foundation of our cadence zones
ACWR Injury Prevention
Acute:Chronic Workload Ratio >1.50 increases injury risk 2-4× (Gabbett, Br J Sports Med 2016)—we track this automatically to keep you safe
Validated Formulas
From Moore's cadence→METs equation to Cost of Transport calculations, every formula includes validation data and clinical interpretation
Advanced Walking Performance Metrics
Professional-grade analysis designed for walkers at every level
Cadence-Based Training Zones
Train with 5 research-backed zones (60-99 spm to 130+ spm) based on CADENCE-Adults study. More practical than heart rate zones—no chest strap needed. Track Peak-30 cadence daily.
Comprehensive Gait Analysis
Track 7 essential gait metrics: cadence, stride length (40-50% height), ground contact time (200-300ms), double support (20-30%), asymmetry (GSI formula), speed, and vertical oscillation (4-8cm).
Training Load Management
Prevent overtraining with Walking Stress Score (WSS) and ACWR tracking. Monitor acute:chronic ratio (keep 0.80-1.30) and get personalized recovery recommendations based on your load.
Biomechanics & Efficiency
Deep stride mechanics analysis and walking economy tracking. Optimize Cost of Transport (~0.48-0.55 kcal/kg/km at 1.3 m/s), identify gait deviations, improve efficiency by 10-15%.
Health Integration
Seamless Apple Health integration. Import walking workouts automatically and sync heart rate, distance, steps, and health metrics. Compatible with Apple Watch mobility metrics (Walking Steadiness, Double Support %, Asymmetry).
Complete Privacy
All your walking data stays on your iPhone. No cloud sync, no accounts, no tracking. Your health metrics are 100% private and secure with local processing. GDPR and HIPAA philosophy compliant.
The Only Walking App Built on Science
Not just step counting—comprehensive analytics backed by biomechanics research
Cadence Over Heart Rate
Why it matters: Heart rate varies with heat, stress, caffeine, illness. Cadence is reliable, practical, and proven. The CADENCE-Adults study showed 100 spm = moderate intensity with 86% sensitivity—more accurate than HR estimation.
Peak-30 Cadence Tracking
Breakthrough metric: Your best 30 consecutive minutes of walking per day independently predicts cardiovascular health and mortality (78,500 UK Biobank participants). We track this daily—no other walking app does.
Injury Prevention with ACWR
Sports science adapted for walking: Monitor your Acute:Chronic Workload Ratio to prevent overuse injuries. Research shows ACWR >1.50 = 2-4× injury risk. We alert you before dangerous spikes occur.
Walking Economy Optimization
Energy efficiency: Track Cost of Transport and walking efficiency (WEI, WALK Score). Improve economy by 10-15% through Zone 2 training, stride optimization, and strength work—with specific guidance.
Gait Symmetry & Fall Risk
Clinical-grade metrics: Calculate Gait Symmetry Index (GSI) to detect asymmetry. Double support >35% and walking speed <0.8 m/s indicate elevated fall risk—critical for older adults and rehabilitation.
50+ Peer-Reviewed Citations
Evidence-based guidance: Every recommendation links to published research. From Tudor-Locke's cadence thresholds to Studenski's gait speed vital sign—transparency in science.

Frequently Asked Questions
What makes Walk Analytics different from other walking apps?
We're the only walking app built on peer-reviewed research. Every metric—Peak-30 cadence, ACWR, Cost of Transport—comes from published studies. We cite 50+ scientific papers and explain the evidence behind each recommendation. It's not step counting; it's biomechanics and exercise physiology applied to walking.
What is Peak-30 cadence and why does it matter?
Peak-30 cadence is your average steps per minute during the best 30 consecutive minutes of walking each day. A breakthrough study of 78,500 people (Del Pozo-Cruz, JAMA 2022) showed it independently predicts mortality risk—even after controlling for total daily steps. We track this automatically, something no other app does.
How does ACWR prevent injuries?
Acute:Chronic Workload Ratio compares your recent training (last 7 days) to your longer-term average (28 days). Research shows ACWR >1.50 increases injury risk 2-4 times. We calculate this daily and warn you before dangerous spikes, helping you progress safely with 5-10% weekly increases.
Why cadence zones instead of heart rate zones?
Cadence is more reliable and practical. The CADENCE-Adults study proved 100 spm = moderate intensity (3 METs) with 86% sensitivity and 90% specificity. Heart rate varies with heat, stress, illness, caffeine—cadence doesn't. Plus, you don't need a chest strap or watch; just count steps.
Can Walk Analytics help with fall prevention?
Yes. We track clinical fall risk indicators: gait speed <0.8 m/s, double support >35%, asymmetry (GSI) >10%, and walking steadiness. These are evidence-based thresholds from geriatric research. Early detection allows intervention before falls occur—critical for adults 65+.
How does Walk Analytics protect my privacy?
All data stays on your iPhone—period. No cloud sync, no accounts, no servers receiving your health data. We process everything locally using on-device algorithms. Your walking metrics, location, heart rate—completely private. We follow GDPR and HIPAA philosophy even though we're not legally required to (since we never see your data).
Do I need special equipment?
No. Walk Analytics works with iPhone or Apple Watch. For basic metrics (cadence, distance, steps), just your phone. For heart rate data and more accurate metrics, an Apple Watch helps but isn't required. We integrate with Apple Health, so any compatible device works.
Is Walk Analytics suitable for rehabilitation?
Absolutely. We're used by rehab patients tracking recovery objectively. The Gait Symmetry Index (GSI) formula quantifies left-right differences (<3% normal, >10% clinically significant). Monitor stride length recovery, walking speed improvement, and asymmetry reduction. Share objective data with your physical therapist or physician.
What's the scientific basis for the 11 formulas?
Each formula includes validation data and original research citation. Example: Moore's cadence→METs equation (R²=0.87, ±0.5 METs accuracy, 76 adults) is 23-35% more accurate than older ACSM equations. We show the science, not just black-box calculations.
