Stress Test Trainer

Know what to expect before your stress test. Follow real treadmill protocols with live heart rate via Apple Watch or Polar H10. Bruce Protocol included free.

Prepare for your treadmill stress test before the day it counts.

Stress Test Trainer guides you through the same standardized treadmill protocols used in real cardiac and fitness evaluations — so when the actual test comes, you already know exactly what to expect.

What it does Step-by-step treadmill guidance through industry-standard protocols. The app tracks each stage, counts down transitions, and monitors your heart rate in real time — so you can focus on training, not watching the clock.

Included free • Bruce Protocol — the most widely used treadmill stress test worldwide. 7 stages, 3 minutes each, increasing speed and elevation.

Additional Protocols — $2.99 each (More to be added) • Balke-Ware Protocol — constant speed, gradual grade increases. 25 stages of 1 minute. A gentler option for those who need a lower-intensity progression. • Cornell Protocol — modified Bruce with intermediate half-stages. 11 stages of 2 minutes. Designed for a more gradual workload increase.

Heart rate monitoring Connect your Apple Watch or Polar H10 chest strap for continuous live heart rate tracking throughout the test. Results are saved with a full HR chart, stage breakdown, and peak BPM — giving you a clear picture of how your heart responds at each level of exertion. More Sensors will be added.

Your results, your history Every session is saved with a complete heart rate chart overlaid on stage bands, average HR per stage, peak BPM, and resting HR. Track your progress across multiple tests over time.

Practice with purpose Knowing the protocol removes one major source of anxiety from the real thing. You'll know when the speed changes, how hard each stage feels, and how your body responds — before it matters.
