It's more than likely that a patient, their family member or a colleague may have recently asked you "Is there an app for that?" Mobile technology is inescapable. It is pervasive in almost every aspect of daily life. Wherever we look, people are often hunched over and fully immersed by a small 6 x 3 inch screen, whether it be walking on the street, travelling on the bus, at the coffee shop or in the clinic waiting room. Mobile devices have infiltrated most aspects of our lives and offer quick, adaptive tech-based solutions to many previously administrative, repetitive or otherwise time-consuming tasks...

Heart activity, or at least heart rate variability, is associated with body position. Our previous studies have confirmed that impedance pneumography may be used to record respiratory function, but the calibration coefficients for this method depend on position. Data were collected from 24 students (12 male, 12 female), who alternated positions between lying (on front, back, and right side), sitting and standing. Signals from an attached iPhone's internal sensors (accelerometer, gyroscope, magnetometer) were recorded and attitude relative to gravity was calculated...
