Your Indoor Workouts Deserve Complete Data

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.

Your Watch Can't See What The Machine Shows

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

But your fitness tracker?

It only captured your heart rate...

All that data on the equipment screen—pace, power, elevation, resistance—stays trapped on the machine.

  • Your watch doesn't connect to gym equipment
  • Remembering every number after a tough session is nearly impossible
  • Your hardest workouts end up looking incomplete when you share them with friends or upload to your training software
For Treadmill Runners

"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."

For Indoor Cyclists

"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."

For Vertical Athletes

"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."

For Cross-Trainers

"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."
