Arrullo: Sleep Sound Mixer Live

Your perfect sleep sound, mixed by you Most sleep sound apps give you one recording and a play button. Arrullo gives you a mixer. Layer up to four sounds at once and set the volume of each one, until the blend is exactly the one that puts you to sleep. Rain over a distant ocean. A fan with a fireplace behind it. Wind in a cave. Your mix is saved, so the next night it is waiting for you. EIGHT SOUNDS, ALL REAL RECORDINGS • Rain • Ocean waves • Stream • Wind • Fireplace • Cave • Fan • Pink noise Every sound is a seamless loop cut from a genuine field recording, and all eight are loudness-matched: setting a slider to the same place gives you the same loudness on any sound, so the fan does not disappear under the rain. SLEEP TIMER Choose 15, 30 or 60 minutes. When the time is up the mix fades out gently over half a minute instead of stopping dead, which is the difference between drifting off and waking up. KEEPS PLAYING WHILE YOU SLEEP Playback continues with the screen off and with the phone on silent, so you can put it face down on the nightstand. WORKS WITH NO INTERNET AT ALL Every sound is inside the app. Nothing streams, nothing buffers, nothing downloads. Airplane mode, a cabin in the mountains, a flight — the app does not care. NO ACCOUNT, NO ADS, NO TRACKING There is no sign-up, no email, no profile. Your mix and your settings stay on your phone. This version shows no ads. GOOD FOR • Falling asleep faster • Masking traffic, neighbours and a snoring partner • Soothing a baby to sleep • Focus and study sessions • Relaxing, reading and meditation • Tinnitus relief at night In English and Spanish. Arrullo is a Spanish word for the sound you make to lull someone to sleep. That is the whole idea of the app. Arrullo is not a medical device and does not diagnose or treat any condition. Please keep the volume low, especially when playing near a baby.
