Sleep better, snore less, and wake up at the right moment — with nothing but your iPhone on the nightstand. DreamWave listens while you sleep, detects snoring, and wakes you during your lightest sleep with a Smart Alarm. Everything is processed privately on your device. No account, no cloud, no Apple Watch required — and if you do wear one, DreamWave reads your sleep stages from Apple Health for an even richer picture. WAKE UP AT THE RIGHT MOMENT • Smart Alarm: pick a wake time and a window (up to 30 minutes). DreamWave rings when you start to stir instead of jolting you out of deep sleep. • Rings even on silent, and keeps ringing on the lock screen if iOS closes the app overnight. • Choose your alarm sound. HEAR EXACTLY WHEN YOU SNORE • On-device snore detection using Apple's sound classifier. • Play back short clips of each snore to hear what your partner hears. • Nightly and 7-day snore trends, intensity timeline and snore score. • Keeps recording through phone calls and Bluetooth changes during the night. SEE EVERY STAGE OF YOUR NIGHT • Sleep score, duration, efficiency and the exact time you fell asleep and woke up — matching Apple Health. • Deep, REM, light and awake breakdown when an Apple Watch is used. • Sleep debt, consistency streaks and a personal sleep coach. WORKS WITHOUT A WATCH • Forgot to start tracking? DreamWave can estimate the night from your iPhone's motion history. • A bedtime nudge when your phone has been still for a while, and a morning summary notification so you know how you slept without opening the app. • Honest numbers: metrics that need a Watch are clearly labelled instead of guessed. DISCOVER YOUR SLEEP DNA • After 21 nights, see your chronotype, your strengths and what to focus on — and share your Sleep DNA card. DRIFT OFF FASTER • 17 soothing rain, ocean, forest and fire soundscapes. • Dream Journal to capture dreams by voice or text. PRIVATE BY DESIGN • Audio is analysed on your iPhone and never uploaded. • No account and no tracking. Your Health data stays on your device. • Available in English, Español, Français, हिन्दी, Bahasa Melayu and Filipino. DREAMWAVE PREMIUM Unlock Smart Alarm, Snore Report with playback, Sleep Coach, Sleep DNA and Dream Journal. • Weekly subscription with a 7-day free trial, or • Lifetime: pay once, keep Premium forever (Family Sharing supported).
