Sleep Sober

Requires a wearable that records overnight heart rate and sleep to Apple Health — such as an Apple Watch. Sleep Sober reads the data your device saves while you sleep, so wear it to bed to get insights. See what your last drink does after lights out. Alcohol keeps your heart working harder while you sleep — and you rarely feel it. Sleep Sober learns your personal sleeping-heart-rate baseline, then quietly flags the nights alcohol pushed it up. How it works • Learns your normal resting sleeping heart rate from your own history • Each morning, checks whether last night ran above your baseline • Tells you when a night looks like a drinking night — and by how much • Knows the difference between a hard workout and a few drinks Personal, not one-size-fits-all Everyone's heart is different. Sleep Sober compares every night against YOUR baseline and YOUR normal variability — never a generic number. The more nights you track, the sharper it gets. Smart about workouts A late workout raises your heart rate too. Sleep Sober learns your typical workout-night pattern and still catches when you drank on top of exercising. A morning wake-up call Get an optional morning alert — only on the nights it detects drinking — showing how many extra beats your heart worked overnight. Set an evening reminder to help you skip tonight. See the toll over time Watch your alcohol-free streak grow, review a 7-night trend, and see the cumulative "extra beats" alcohol has cost your heart.
