One clean workout. (even if you recorded it three times)
Whether you train on one device or five, Athalyze keeps your training data clean and accurate. When multiple devices record the same workout, it combines them into one activity, selects the most reliable data per metric, and keeps the originals so you can compare.
Connect your data
Athalyze supports integrations with Apple Health, Garmin Connect, Oura, Strava, and Whoop.
How it works
Import from every device, merge into one activity, then analyze with confidence.
Import
Workouts from all supported integrations are automatically imported upon completion. You can also manually upload workout files.
Unify
Athalyze automatically combines multi-device workouts into a single activity and selects the best data for each metric.
Analyze
By default, Athalyze shows your unified activity with the best data source automatically selected for each metric. When you want a deeper dive, you can compare all input data sources.
Every device. One clean result.
Switch between every raw input and the single clean result Athalyze builds from them.
All your inputs, one chart
All your devices on the same chart. Spot where they agree, where they differ, and exactly what each one recorded.
One clean result
The same workout, cleaned up. One source per metric, selected automatically so your training log is accurate from the start.
Beautiful 3D maps
Every route rendered in three dimensions. Rotate, zoom, and explore the terrain. The map stays linked to your charts. Scrub through any metric and your position updates on the route.
Powerful enough for data nerds. Clear enough for everyone.
Personal records, curves, histograms, trends, and gear. Your training history analyzed from every angle. Deep data, presented simply.
Personal Records
Every PR, every distance, every discipline. Distance and power records for running, cycling, and more. Filter by activity type and narrow to any time period to see how your bests have shifted over time.
Curves
Your best effort at every distance or power duration, plotted as a single curve. Pin a previous time period to compare and see exactly how your fitness has shifted.
Histograms PRO
How much time are you spending at each metric? Plot one time period or overlay two to see whether your training distribution is moving in the right direction. Options range from pace and power to advanced metrics like ground contact time and power balance.
Correlation Heatmaps PRO
See how your pace relates to your stride length, how your cadence affects your ground contact time, or any other combination of metrics. Pick any two, any time period, across all your activities. Compare two periods side by side to see the differences.
Activity Trends
See how your running and cycling distance adds up over time. Daily, weekly, monthly, and yearly views with month-over-month and year-over-year comparisons to track how your training volume is trending.
Step Trends
See your step totals at any scale. Daily, weekly, monthly, and yearly charts with month-over-month and year-over-year comparisons to spot whether your daily movement habits are improving over time.
Gear Tracking
Track every piece of gear you train with. Monitor mileage so you know when to replace it, filter by active or retired, and search by name, brand, or model.
Gear Details
Drill into any item for the full picture. Usage stats, active time, purchase price, price per mile, and every activity that item has been part of.
Devices
Your complete device history. Every sensor, watch, and bike computer you have ever used, with device details, usage stats, and activity history for each one.
Device Details
Go deeper on any device. Hardware specs, usage stats, active time, and a battery history for devices that support it.
Advanced metric support
- Import FIT files and developer fields, plus supported sensor data.
- See metric changes within a single activity when available, such as heart rate switching between Apple Watch and AirPods Pro.
- When viewing heart rate, inspect the original R-R interval data for beat-to-beat timing detail.
- Keep the originals so you can audit the unified result whenever you want.
- Set per-device metric priorities to control which device wins for each metric.
Free to use. Pro to go deeper.
