Other trackers tell you sleep was bad. Drift tells you what to do about it — tonight, this week, this month — using the same CBT-I protocol clinicians use.
Adaptive sleep restriction. Four protocol tracks (standard, shift-work, perimenopause, chronic pain). Passive Apple Health validation. On-device snore detection. Audiogram-tuned pink noise. An AI coach you can ask anything at 3am.
Audio is classified on-device — never uploaded. Your sleep diary stays in your account. No ads, no data sale.
