iPhone
Sleep better, wake refreshed. Track your sleep cycles, get smart alarms, and discover what quality rest feels like with detailed phase analysis and personalized insights.
Discover what happens while you sleep. Slumber is the complete sleep cycle tracker that analyzes your nights, identifies patterns, and helps you sleep better every day.
TRACK YOUR SLEEP WITH PRECISION
Connect with Apple Health and automatically monitor every phase of your sleep cycle: deep sleep, light sleep, REM, and awake periods. Slumber transforms complex health data into a simple, clear sleep quality score so you truly understand how well you are resting each night.
WAKE UP AT THE RIGHT MOMENT
The Smart Alarm is what sets Slumber apart. Instead of jolting you awake at any random moment, it identifies the lightest phase of your sleep within a customizable window of 15 to 60 minutes before your scheduled time. The result: mornings without grogginess, with more energy from the very first minute of your day.
UNDERSTAND YOUR PATTERNS
Track weekly and monthly statistics that reveal how your sleep evolves over time. See your average duration, bedtime, consistency, and trends. Compare periods and identify what works best for your body and your routine.
