About Lucid: Sleep Tracker & Sounds
Track your sleep, block distracting apps, and read your nightly metrics — all from your phone. No wearable needed. Lucid uses your iPhone's microphone and sensors to analyze your sleep, then gives you personalized coaching to help you wake up feeling restored. Your AI Sleep Coach learns your unique patterns and delivers tailored recommendations — from adjusting your bedtime routine to optimizing your sleep environment. Listen back to sleep recordings, catch snoring moments, and see exactly what happens while you rest. Features: AI-powered sleep coaching based on your nightly data. App blocker to cut screen time before bed. Ambient sounds and guided relaxation to help you fall asleep naturally. Sleep score, streaks, and badges to keep you motivated. Daily mood and energy logging for smarter insights over time. Lucid turns your phone into the only sleep tool you need — no watch, no ring, no extra device. Premium features including Sleep Sounds, AI Sleep Coach, Sleep Insights, and Smart Wake-Up require a monthly ($4.99) or annual ($39.99) subscription.
