About

Sleep Only

Sleep Only turns your bedroom into a sleep sanctuary. White noise, fan sounds, rain, and ocean waves, composed in real time to help you fall asleep faster, stay asleep longer, and wake up more rested. Built by Adaptive Sound Technologies Inc. (ASTI), the team behind LectroFan(TM) and Sound+Sleep, Sleep Only holds the SleepMark(TM) designation for meeting National Sleep Foundation guidelines on product design, evaluation, and documentation. An independent study by SleepScore Labs found that Sleep Only helps users sleep, relax, and unwind better. Choose from a curated library of sleep-promoting sounds: white, pink, brown, and green noise, fan sounds, nature and water compositions, lullabies, and 40 Hz therapy beats. The catalog draws from ASTI's acclaimed LectroFan and Sound+Sleep collections, plus sounds built specifically for Sleep Only. WHY SLEEP ONLY IS DIFFERENT Adaptive Sound Technology (Premium): Sleep Only is the only sleep sound app that automatically adjusts volume and sound content based on the noise in your room. On mobile, the adaptive feature now covers the entire catalog, up from a limited set previously available only on ASTI's Sound+Sleep hardware. Non-looping audio: Most sound machines and apps repeat the same loop all night. Every category in Sleep Only, except lullabies and 40 Hz therapy beats, plays without repeating. Expertly mastered sound: Our audio team built each composition to promote relaxation and sleep, tested and refined for quality most sound apps skip. A calm, focused interface: No busy dashboards or gamified streaks, just the sounds you need to fall asleep. FEATURES - Non-looping, high-fidelity sound compositions generated in real time on your phone or tablet - Patented Adaptive Sound Technology that reads your room and adjusts automatically (Premium) - A simple, distraction-free sound catalog with a customizable favorites list - A shut-off timer you can set to the exact hour and minute, up to 23 hours and 59 minutes - 11 language options: English, French, Spanish, Portuguese, Dutch, German, Italian, Polish, Korean, Japanese, and Chinese - Bluetooth support for your speaker of choice - No internet connection required after the first download SUBSCRIPTIONS Standard - Over 35 non-looping, high-fidelity sounds across Noises and Fans - Shut-off timer Premium - Over 120 high-fidelity sounds across six categories: Noises, Fans, Nature, Water, Lullabies, and Other - Shut-off timer - Patented Adaptive Sound Technology, with control over minimum and maximum volume, ramp rates, and microphone sensitivity Terms of Service: https://www.soundofsleep.com/app-terms Privacy Policy: https://www.soundofsleep.com/app-policy
