ZenMark app for iPhone and iPad

Conquer yourself with ZenMark - Using the latest in wearable heart rate technology, ZenMark has developed a new method for tracking mental stress throughout the day. It also gives near real-time alerts to unplug when high stress is detected.

HOW?
During periods of mental stress, the brain sends a fight or flight signal to the heart which affects its rhythm; it also has a separate signal for relaxation. ZenMark does a beat-to-beat analysis to measure this heart rate variability.

Due to the precise nature of our calculations, at this time, we recommend using either:
- Mio Alpha (Heart Rate Watch)
- Polar (Heart Rate Watch or Chest Band)
