iKeepAtive is a fitness scheduling app, designed primarily to help users schedule their workouts and integrate with the system calendar to make sure you do them.

iRelief is an app that provides a breath control training for the user to practice controlled training techniques, while providing bio-feedback on the user's training data. Using photoplethysmographic techniques and the iPhone's camera, iRelief is able to measure the heart rate and calculate Heart Rate Variability (HRV) just by placing the user's fingertip on the camera lens. The HRV is a measure taken by the beat-to-beat interval of the user's heartbeat, which based on existing research, increases as we inhale and decreases as we exhale.
