CardioMood - heart rate variability expert tool app for iPhone and iPad

- CardioMood application allows you to measure your Heart Rate Variability (HRV).
Our heart is controlled by autonomic nervous system, and heart rhythm reflects its state. By analyzing beat-to-beat variability (also known as HRV), we can estimate the ratio of activity of sympathetic and parasympathetic nervous systems.

- Use CardioMood for stress estimation
Stress is often associated with higher heart rate and blood pressure as well as more regular rhythm (low variability). In contrast, a relaxed state is usually associated with high HRV.

If youre an athlete heart rate variability will allow to track your recovery, and changes in HRV will indicate development and adaptation of cardiovascular system to training. Use it to maximize the performance.

- CardioMood utilizes HealthKit for better user experience. You will be able to save the heart rate to your HeathKit store on every CardioMood session.


How to use the application:
1. Put on your heart rate sensor (Polar H7, Mio alpha etc.) and relax (take a sit or lie down).
2. Establish connection with your heart rate monitor.
3. Click "Start".
4. Measure from 2 to 5 minutes. You may measure for a longer period if you need.
5. After finishing the recording see your heart rate graph with average stress level.

Important: If you cannot connect to your heart rate sensor, make sure that it is not connected to another device at the moment.

Important: If you see a lot of artefacts or ectopic beats, try to adjust the sensor to ensure good connection and repeat the procedure.
