iPhone Giveaway of the Day - Active app

Track your activity and physiology & gain unique insights using. Active automatically tracks your activity & sleep, together with your heart rate and heart rate variability.

By combining activity tracking and physiological measurements, Active can provide unique insights on you and your lifestyle.

Active requires an iphone 5S.

MAIN FEATURES
- Activity tracking clustered for intensity level (light, moderate and vigorous physical activity)
- Heart Rate and Heart Rate Variability using the phone's camera, no additional sensors required
- Calories counting (including basal metabolic rate and physical activity energy expenditure, computed from different clusters of activities)
- Sleep tracking
- Insights combining activity, sleep, body weight and physiological data
- Export all data (activities, sleep, heart rate, heart rate variability, locations, body weight, etc.)

ADDITIONAL FEATURES
- Body weight tracking
- Add manual activities (e.g. Gym workout)
- Personal dashboard visualizing data at 10 minutes resolution
- Personal goals

ACTIVITY - Keep Moving
Active uses the iPhone's M7 coprocessor to monitor physical activity levels without draining any extra battery. Activities are clustered in three groups based on activity intensity, and calories burnt are computed for each cluster. Locations on the other hand are acquired using 3G/GSM and WiFi networks only. In this way Active can provide accurate physical activity tracking without affecting your phone's battery lifetime.

HEART RATE VARIABILITY - Stress & Overtraining
By reliably measuring your Heart Rate Variability using the phone's camera, Active can estimate autonomic control of the heart, and in particular parasympathetic control.

Analysis of autonomic regulation and sympathetic/parasympathetic activity can then be used to assess physiological stress level (both mental and physical, for example to prevent overtraining) under different contexts.
