Drift is a smart sleep tracker that helps you understand and improve your sleep — no wearable required. Simply log your bedtime and wake time each morning, rate your sleep quality, and track factors that affect your rest. Drift does the rest, calculating a personalised sleep score and revealing the patterns behind your best (and worst) nights. SMART SLEEP SCORING Your sleep score is calculated from five key components: - Duration: How your sleep length compares to the recommended 7-9 hours - Timing: Whether your sleep window aligns with your body's natural rhythm - Consistency: How regular your schedule is from night to night - Quality: Your self-rated restfulness each morning - Factors: The impact of caffeine, exercise, alcohol, stress, and screen time Each factor contributes to a score out of 100, giving you a clear picture of your sleep health at a glance. SLEEP DEBT TRACKING Think of your sleep reserves as a battery. Every night of poor sleep drains it; every good night charges it back up. Drift tracks your accumulated sleep debt and shows you exactly where you stand. Watch your battery fill as you recover, and understand how long it takes to bounce back from a rough week. FACTOR TRACKING Log what matters. Track caffeine intake, exercise, alcohol, stress levels, and screen time before bed. Over time, Drift reveals which factors help and which hurt your sleep, so you can make informed changes. STREAKS & MOTIVATION Build a logging streak and stay consistent. Drift rewards regular tracking with streak counts and encourages you to maintain healthy sleep habits through daily engagement. BEAUTIFUL DARK THEME Designed for bedtime. Drift features a clean, dark interface that's easy on your eyes when you're logging before sleep or checking your score first thing in the morning. OFFLINE-FIRST Log your sleep anytime, even without an internet connection. Your data syncs automatically when you're back online. No missed entries, no lost data. PRIVACY-FOCUSED Your sleep data is stored securely in AWS (London, UK), encrypted at rest and in transit. We never sell or share your data. You can export or delete your data at any time. Fully GDPR compliant. NO WEARABLE REQUIRED Unlike other sleep trackers, Drift doesn't need a smartwatch, fitness band, or any hardware. Manual logging puts you in control and removes the need for uncomfortable devices in bed.
