Our goal at SleepWatch is to help you sleep better. One way we aim to achieve this is by providing you with easy access to personalized insights that we believe can help reveal something important about your sleep and overall health. With more data at your disposal, you may be able to make better choices to help you achieve your best sleep. Our newest feature introduces the ability to track your Sleeping Heart Rate Variability (HRV). This new sleep metric—which is not the same measure as heart rate—may reveal unique attributes about your sleep quality and well-being.
