Sleep, understood

Find out what's stealing your sleep.

Clearbrain looks at your Apple Watch data and your daily habits together — and tells you, in plain language, what's actually affecting your deep and REM sleep.

Requires iPhone and Apple Watch. Free to try.

No guessing

Clearbrain doesn't just log your sleep. It looks for patterns across alcohol, caffeine, exercise, stress, and more.

Clear insights

Not charts and data dumps — one or two things to pay attention to, explained in plain English.

Hopeful, not alarmist

Every insight comes with context. Understanding what's happening is the first step to changing it.

Clear, actionable takeaways — not noise. What to try changing, and why it might help.

What Clearbrain looks at

Your sleep is the result of dozens of small decisions.

Clearbrain doesn't tell you to sleep eight hours. It tells you that your deep sleep tends to drop by 40 minutes when you have coffee after 2pm — because that's what your data actually shows.

Deep sleep duration
REM sleep duration
Sleep consistency
Caffeine timing
Alcohol intake
Exercise intensity
Screen time
Stress levels
Meal timing
Heart rate variability

Better sleep is possible.

You just need to know where to look. Clearbrain shows you the way.
