Most sleep trackers are single-player, making it hard to stay motivated. Slumber turns sleep tracking into a social experience for both iOS and Android. Instead of just logging data in a vacuum, you can track your nightly metrics, visualize your trends, and connect with your friends to hold each other accountable. See who is actually getting the best rest and build healthier habits together.

Wearable sleep scores never told me if I actually slept well. Slumber reads Apple Health and lets you post your night for friends to see, with a Compare tab for side-by-side stats (asleep, deep, REM, bedtime, wake events). Baseline from people you know, not a population average. Works with Oura, Whoop, Apple Watch, Garmin. iOS, free. Best with a friend on it.
