Unlike other free sleep trackers for Apple Watch, we're focused not just on more data, but helping you actually sleep better and get more shuteye.
Your Apple Watch tracks sleep stages, heart rate, heart rate variability (HRV), blood oxygen, ECG, temperature, and more-but what does all that data mean? More importantly, what do you actually do to get more shut eye?Įmpirical Sleep distills your Apple Watch health data into one simple sleep score, then suggests actions to help you improve your sleep duration, onset, and quality.
