Motion Cap - Physical + Mental
Monitor strenuous activities
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
See how stressful moments — arguments, anxiety, public speaking — affect your body. Get alerts before exceeding your max heart rate. Stay aware. Stay in control.
Motion Cap helps you understand how life's stressful moments affect your body — arguments, anxiety, public speaking, parenting, and more — by monitoring your heart rate, motion, and sound in real time.
Set your maximum heart rate — either from your doctor's recommendation or an age-based estimate and Motion Cap will alert you when you're getting close. A haptic warning lets you know it's time to slow down, even when your phone is out of sight.
Key Features:
- Real-time heart rate monitoring via Apple Watch
- Customizable max heart rate based on your doctor's guidance or age
- Adjustable heart rate alert threshold
- Haptic and visual alerts when approaching your limit
- Heart rate zone tracking (Rest, Light, Moderate, Hard, Maximum)
- Live waveform showing motion, noise, or heart rate intensity
- Activity groups with per-activity detection controls — choose which sensors (motion,
heartbeat, noise) are active for each situation
- Session history with detailed summaries and activity group filtering
- Heart rate zone breakdown for each session, showing time spent in each zone
- Trends and charts tracking your activity over 7, 30, 90, and 360 days — filterable by
activity group
- Session notes to record how you felt
- Trimming tool to adjust session start and end times
- Shareable PDF session reports
- All data stays on your device — no accounts, no cloud, no tracking
How It Works:
Place your iPhone nearby and start a session. Motion Cap uses your phone's accelerometer and microphone to detect motion intensity and noise levels. Optionally pair an Apple Watch for real-time heart rate streaming — the app combines signals for a complete picture of how your body responds.
Built for Awareness:
Whether you're managing anxiety, navigating tough conversations, recovering from surgery, or simply following your doctor's advice to keep your heart rate in check, Active Cap helps you see the connection between your daily stressors and your body's response.
Motion Cap is not a medical device. Always consult your doctor about your health limits.

Key changes from the original:
- Opening reframed from "physical activity" to specific emotional/social situations
- Added noise detection, per-activity sensor controls, adjustable alert threshold, PDF sharing,
activity group filtering on trends
- "Built for Safety" → "Built for Awareness" with anxiety/conversations leading the examples
- Cardiac rehab/surgery kept but moved after the mental health use cases
- Closing disclaimer softened from "exercise program" to "health limits"
