Your phone knows more about your sleep than you think. Track how long you sleep, how well you sleep, and what you can do to sleep better - all automatically.
Apple Health (iPhone) and Google Fit (Android) track basic sleep automatically. For detailed insights, try Sleep Cycle (free) on your nightstand - it detects sleep phases and wakes you at the optimal time. A smartwatch adds heart rate and blood oxygen data for even better tracking.
Most people don't realize how poorly they sleep until they see the data. Sleep tracking reveals patterns you can't feel.
You may think you sleep 8 hours, but tracking often reveals you're only getting 6. Knowing the truth is the first step to fixing it.
Late coffee, screen time before bed, or irregular schedules - your sleep data shows which habits disrupt your rest.
Poor sleep is linked to heart disease, diabetes, and memory issues. Tracking helps you catch problems early and share data with your doctor.
Smart alarms wake you during light sleep instead of deep sleep, so you feel refreshed instead of groggy every morning.
You don't need a smartwatch. These apps use your phone's sensors to track your sleep from your nightstand.
The most popular sleep tracking app. Place your phone on your nightstand and it uses sound analysis to detect your sleep phases.
Uses sonar technology through your phone's speaker and microphone to track breathing and movement without touching your phone.
Built into every iPhone. Set a sleep schedule and your phone automatically tracks when you fall asleep and wake up.
The Google Clock app includes a "Bedtime" feature that tracks your sleep schedule and shows weekly reports in Google Fit.
Wearing a smartwatch to bed gives you the most detailed sleep data, including heart rate, blood oxygen, and true sleep stages.

Sleep apps give you numbers, but what do they actually mean? Here's a plain-English guide to the key metrics.
How many hours you actually slept (not just how long you were in bed). Adults over 65 need 7-8 hours per night.
Your brain cycles through Light sleep (body relaxes), Deep sleep (body repairs), and REM sleep (brain processes memories and dreams). You need all three.
The percentage of time in bed that you actually spent sleeping. Above 85% is good. Below 75% means you're spending too much time lying awake.
How many times you woke up during the night. Some waking is normal (1-2 times), but frequent waking may indicate a problem worth discussing with your doctor.
Your resting heart rate should dip 10-20% below your daytime rate. If it stays high, it may indicate stress, illness, or sleep apnea.
Tracking alone doesn't help - acting on the data does. Here are proven changes based on what your app reveals.
If your data shows irregular bedtimes, set a fixed schedule. Going to bed and waking up at the same time - even on weekends - is the single most effective sleep improvement.
If your app shows you're falling asleep late despite being in bed, blue light from screens may be the cause. Enable Night Mode on your phone 1 hour before bed.
If your data shows restless nights, check for patterns: caffeine after 2pm, large meals before bed, or alcohol in the evening can all disrupt deep sleep.
Consistent snoring, low blood oxygen, or frequent wake-ups could indicate sleep apnea. Bring your sleep data to your next appointment.
You can start tracking your sleep in under 5 minutes with your phone.

Common questions about tracking your sleep with technology.
Yes. Apps like Sleep Cycle and SleepScore use your phone's microphone and accelerometer to detect movement and breathing. Just place your phone on your nightstand.
