Your cardio machine knows exactly what you did—distance, pace, power, elevation. But none of that makes it to your training log. CardioCapture captures your complete indoor workout data so you can track real progress, make smarter training decisions, and stay motivated. Because when you see the work, you keep showing up.
The StairMaster says 82 floors
The bike shows 215 watts average
The treadmill tracked intervals at 8% incline
The elliptical tracked a VO2 Max interval workout
It only captured your heart rate...
All that data on the equipment screen—pace, power, elevation, resistance—stays trapped on the machine.
"Training for an ultra means hours on the treadmill with incline work. CardioCapture's workout builder turns my elevation training into actual vertical gain data. My training software finally calculates accurate TSS from my indoor sessions."
"Spin class and stationary bike sessions used to be invisible in my training log. Now I record every watt and every effort. My training plan is finally accurate and my cycling buddies can see what I'm doing when weather keeps me inside."
"100-miler prep means brutal StairMaster sessions. CardioCapture converts floors to elevation so my coach can see my vert work and I can share climbing sessions with my ultra running community. The data is finally there."
"I alternate between treadmill, bike, and stair stepper to prevent injury. CardioCapture tracks all of it accurately with real-time recording. My weekly training load is correct and I never lose workout data again."
Describe your session in plain English and let AI structure it, or build intervals manually with full control over every segment.
Record your workout as it happens with per-second sampling. Adjust speed, incline, and mark laps on the fly.
Review every metric after your session—HR zones, pace curves, incline charts, and effort scores all in one place.
Track your endurance profile, anaerobic threshold, and effort trends over time to make smarter training decisions.
Import heart rate from Apple Health, Garmin, COROS, or any device that exports workout files. One complete file with pace, power, elevation, and HR zones—exactly like your outdoor sessions.
Incline converts to real elevation gain - 528 feet from a 3-mile run at 5% grade finally shows up accurately
Power and cadence data captured precisely—your 215-watt effort gets logged correctly for training software
Floors convert to elevation using your exact machine model — 82 floors = 888 feet of climbing elevation
Resistance and stride data captured—your cross-training sessions finally count toward your weekly totals
Record your workout as it happens with per-second data sampling. Auto-split laps, adjust speed and incline on the fly, and get a complete session file when you're done—no post-workout data entry needed.
Use Smart Build, manual entry, or record in real time
From Apple Health or your fitness wearable (optional)
Dive deeper into your stats right on CardioCapture, or export to your favorite fitness tracking platform. You'll always have full control over your workout files.
Yes. CardioCapture works with any treadmill, bike, stair stepper, or elliptical. You enter the data from your machine's display—or record in real time—and CardioCapture handles the rest, including elevation calculations calibrated to your specific equipment model.
Yes. CardioCapture creates standard FIT files that any fitness platform can read. Your elevation, power, and interval data displays correctly in Strava and other platforms.
No. You can import heart rate data from Apple Health, Garmin, COROS, Polar, Wahoo, or any device that exports FIT files. Or skip heart rate entirely—the app still captures all your equipment data perfectly.
Absolutely. Every field is editable before you upload. You can adjust times, distances, segments, and more to ensure your workout data is exactly right.
Yes. The app generates workout files on your device and saves them locally. Internet is only needed for uploading to Strava or using the AI Smart Build feature.
Yes. CardioCapture creates standard FIT files that work with any fitness platform. Export once, share anywhere.
