You know you were up twice last night. Your tracker says you slept perfectly. Drift shows you what actually happened — with the honesty to say when it's unsure.
“I was up at 2am for 5 minutes. Apple said I slept 7 hours straight. Drift caught it.”
— Beta tester, coming soon
A few steps at 2am? That's a wake event. Period. We bias toward catching interruptions, not smoothing them over.
When you activate Sleep Focus, we know you're heading to bed. No manual logging. We track how long it takes you to actually fall asleep.
Not all sleep is equal. See which hours were truly restful (zero motion, stable heart rate) versus restless asleep.
Correct any classification and Drift adapts. After a few weeks, it knows your sleep patterns better than any generic algorithm.
See 'Drift tracking' when you check the time at 2am. In the morning, your sleep summary is right on your watch face.
If we're not sure, we say so. 'Low confidence' is more useful than a wrong answer dressed up as a sleep score.
That's it. No buttons to press, no session to start. Your Apple Watch already collects heart rate, motion, and step data overnight.
When you wake up, Drift analyses every minute of the night. Steps, motion patterns, heart rate changes — all processed on-device. Nothing leaves your watch.
Your morning review shows a clear timeline: when you were asleep, when you were awake, and when we're not sure. Wake events are the headline, not hidden in a chart.
Tap any segment to confirm or correct it. Drift learns your patterns and gets more accurate every night. By week two, it knows you.
Yes, we deliberately don't have a sleep score. You don't need a number — you need to know what happened.
