Drift teaches the CBT-I techniques clinicians use — a guided sleep-window plan you follow yourself, built from your own morning diary. Trackers measure your sleep. Drift is built around the intervention side: each week it reviews your diary and suggests how your in-bed window could move, using the published sleep-restriction titration rules (AASM clinical practice guideline; Edinger 2021), with a hard 6-hour minimum window and the full reasoning shown for every suggestion. NO FAKE SLEEP SCORE Your real sleep efficiency — time asleep over time in bed — charted against the 85% goal line from the published literature. No proprietary composite number, no grades. A 60-SECOND MORNING DIARY Apple Health pre-fills what it can (sleep stages, HRV, resting heart rate) so you confirm instead of typing. The diary accepts any schedule, including cross-noon and rotating shifts, and "not sure" is always an answer. BUILT FOR REAL SCHEDULES - Standard track for classic insomnia patterns - Shift-work track with a higher safety floor - Perimenopause track that doesn't penalise hot-flash wake-ups - Pain-aware track with gentler pacing READS APPLE HEALTH, NEVER WRITES TO IT Drift is read-only on Apple Health, so it can't alter or corrupt your existing health data. AUDIO NEVER LEAVES YOUR IPHONE On-device snore, cough, and sleep-talk detection stores only event labels — never recordings. Plus audiogram-tuned pink, brown, white, and rain noise. SAFETY-FIRST BY DESIGN A real safety screener: bipolar disorder, seizure history, and untreated sleep apnea switch Drift to diary + education mode, where the window never narrows. Drowsy-driving warnings are built in, and the window never goes below 6 hours. AN HONEST FREE TIER The morning diary, your efficiency trend, stimulus-control education, your first computed window and your first weekly review — free, forever. Drift Pro continues the weekly reviews and adds the coach, sound analysis, pink noise, and sleep stories.
