Lull layers ambient sounds into mixes that quiet a busy mind. Drop rain over distant thunder, page turns, and crackling fire โ€” eight curated scenes to choose from, plus a 66-sound library to build your own. Save unlimited custom mixes with your own cover photos. The sleep timer fades quietly to silence so it doesn't wake you. Standard playback controls work from the lock screen and Control Center. ASMR triggers, white-noise focus aids, brown noise for sleep, weather scenes, page turns, soft tapping, gentle brushing โ€” every layer adjusts independently, so you compose exactly the texture you need. PRO LIFETIME One payment unlocks every scene, the full sound library, unlimited saved mixes with custom covers, the sleep timer, and every scene we add in future updates. No subscription. Yours forever.

Cocon Sleep is a gentle bedtime companion that helps you fall asleep calmly, without pressure and without a sleep score to worry about. WHAT YOU GET: - A quick, gentle morning check-in: how you feel, a little context if you want, and never a grade. - Soothing sleep sounds (soft rain, brown noise, slow waves) with an automatic fade-out from 15 min to 1 hour. - A black screen mode so your phone never dazzles you at night. - A simple view of your week, in words instead of numbers. - Gentle evening and morning reminders, if you want them. COCON+ (OPTIONAL): - Extra sounds: rain on a tent, crackling fireplace, low-frequency waves. - Sound mixer: layer up to 3 sounds and save your mixes. - 4-7-8 breathing before bed. THE COCON PROMISE (PRIVACY): Your check-ins stay on your device only. The only third-party service is RevenueCat, used solely to manage your subscription. No trackers, no ads, no sleep data shared. Cocon+ is available as a monthly or yearly subscription with a 7-day free trial. Payment is charged to your Apple Account when the trial ends. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period, in your Apple Account settings. No fake discounts, no countdown timers.
