Set Up in Three Steps
From install to your first AI coaching brief in under five minutes.
Link Strava, Apple Health, or Health Connect. Your activities, sleep, HRV, and heart rate data flow into IronStride automatically. No manual entry.
IronStride's AI processes your training history, recovery trends, weather conditions, and health signals to build a complete picture of your fitness state.
Every morning, get a personalised coaching brief — what to train, how hard to push, what the weather means for your workout, and how close you are to race-ready.
Your Coach. Every Day.
Not a generic training plan. IronStride's AI reads your actual training history, recovery state, health signals, and local conditions to generate a coaching brief written specifically for you, for today.
Every brief includes a recommended workout, your recovery score, strain load context, race readiness percentage, and weather and air quality alerts — all in plain language you can act on immediately.
After every Strava activity, AI analyses your performance, compares it to your baseline, and tells you what it means for your next training session.
Today's Recommendation
Easy 8 km at Zone 2 heart rate. Your body has absorbed last week's long run well. Keep intensity low and protect aerobic base ahead of your race block.
Syncs with What You Already Use
No duplicate data entry. IronStride pulls your data directly from the services you already trust.
Strava
OAuth 2.0 connection to Strava. Every run, ride, and swim is automatically fetched, analysed by AI, and factored into your coaching brief.
Apple Health
iOS integration via HealthKit. Reads your HRV, resting heart rate, sleep stages, and steps — the recovery signals that matter most.
Health Connect
Android Health Connect integration. Full access to the same recovery metrics — HRV, sleep, and heart rate — from Garmin, Polar, Fitbit, and more.
Know When to Push. Know When to Rest.
Five signals, one clear picture of your daily readiness. IronStride combines them so you never have to guess.
Recovery Score
Combined daily readiness from sleep, HRV, and training load. Your go/no-go signal.
Strain Score
How hard have you been training? Daily and weekly load tracked against your fitness baseline.
HRV
The most sensitive indicator of nervous system recovery. Rises when you're adapting, drops when you're overdoing it.
Resting HR
Elevated resting HR often signals fatigue or oncoming illness before you feel it consciously.
Sleep Analysis
Duration and quality from your wearable. The single biggest lever for athletic adaptation.
Train with the Elements, Not Against Them
IronStride fetches local weather and air quality data so your coaching brief accounts for the conditions you'll actually run in.
AQI Monitoring
Real-time Air Quality Index for your training location. IronStride advises on whether outdoor training is safe, and suggests the best window of the day when AQI is high.
Heat Stress
Temperature and humidity combine to create real physiological stress. IronStride calculates heat impact on your target heart rate zones and warns when conditions require pace adjustment or postponement.
Weather Impact
Wind, rain, and humidity all affect perceived effort and sustainable pace. IronStride adjusts your targets and gives context so you don't chase a pace number that today's weather has already changed.
Built to Respect You
Your health data is private. IronStride is built with privacy-first architecture from day one.
Offline First
Your coaching brief and historical data are available without an internet connection. IronStride syncs when you're online and works fully when you're not.
Privacy First
Your health data is never sold, never used for advertising, and never shared with third parties beyond the services required to run the app. Read our Privacy Policy.
South Asia Optimized
Built for athletes training in Bangladesh, India, and South Asia — where heat, humidity, and air quality are real performance and safety factors, not edge cases.
