"A sheep beside you, on the nights you sleep alone." Sheep Lullaby is a sound app for the time between lying down and falling asleep. Lullabies, ambient sounds and a sheep named Merry keep you company until you drift off. - Pick your sounds Choose from lullabies, ambience and voices, and line them up into your own playlist. Tracks play in the order you set, and the volume bar lets you find just the right level. - Save it as a playlist Keep an arrangement you like as a playlist and bring it back with one tap the next night. Tracks you return to can be kept as favourites. - Set a timer Off, 15, 30, 45, 60 or 90 minutes. When the time is up, the sound fades out gently over about 30 seconds and stops on its own, so it is fine to fall asleep first. The timer counts the time you actually listen. Pause the sound and the timer pauses with it; resume and it picks up where it left off. - Beat mode Two tones of slightly different pitch, one in each ear, make a slow pulse. It is meant to be used with earphones or headphones. When you are not wearing them, there is a calm mode made for speakers. Please read the safety notes inside the app before the first use. You can read them again at any time from Settings > About. - Sheep Count (in-app purchase) A voice counts sheep from 1 to 100, ready to add to your playlist. Choose a whisper, a blunt and prickly tone, or a childlike voice. - Made for a dark room The night dimmer takes the screen darker than usual. Buttons are large and sit within reach of one hand while you are lying down. You can also choose a light, dark or system appearance theme. - Built to stay out of the way - Playback continues when the screen goes off or you switch to another app, and you can control it from the lock screen. - By default, audio is downloaded over Wi-Fi only. Downloading over mobile data can be turned on in settings. - Downloaded audio can be removed at any time from "Manage downloads", one track at a time or all at once. Deleting it does not remove what you bought, and you can download it again whenever you need it. - About pricing The app is a one-time purchase. The four items of extra content are also one-time in-app purchases, not subscriptions. There is nothing to cancel and no monthly billing. If you change devices or reinstall, "Restore purchases" inside the app brings your content back. - Privacy - No account is required. - No usage analytics (the app contains no analytics SDK). - No advertising, and no use of the advertising identifier. - No permission requests for location, contacts, camera, photos or microphone. - Your settings, favourites and playlists stay on your device. - Languages Japanese and English (Settings > Appearance > Language). - Before you use it This app is not a medical device.
