HeartCloud (https://heartcloud.io) is a secure web application that makes your Apple Watch so much more useful. Your health data is visualized in new ways, you can compare different time periods to see health trends, and, importantly, you can see if your health data is within normal ranges day-to-day based on your age. Our platform helps you manage: 1. Apple Health data. HeartCloud organizes and makes searchable what Apple Watch natively captures (heart rate, heart rate variability, and resting heart rate), but also explores information sourced from third party hardware like glucose monitors, blood pressure cuffs, and spirometers. 2. Workouts. Whether its runs, swims, hikes, walks, cycling, rowing, etc., HeartCloud beautifully displays the metrics from your workout. This includes mile times, strokes per lap, workout routes displayed on maps, comparing workouts, and seeing performance changes over time 3. Daily Activity. HeartCloud displays your month-to-month and daily history of movement-related activity and goals. 4. Insights. There are particular questions about our own health we wanted to know: how does step count affect resting heart rate? How does my heart behave during and after a workout? Are my heart rate recovery times improving? When during the day am I sedentary but my heart rate is high? Each of these is addressed by a HeartCloud "Insight," a deep dive into a particular data question. Lastly, HeartCloud for Organizations (https://organizations.heartcloud.io) exists to provide medical professionals with a means to view their own patients' HeartCloud data, and also to provide useful software tools to make greater use of the Apple Watch in a clinical setting. PIt's incredibly secure, sharing control is vested exclusively in the patient, and sharing can be altered or turned off at anytime.
