I live in a big city, and we have an often-crying newborn baby in the apartment next door. We plug into a logitech speaker unit and use the fan noise to sleep more soundly every night. \"\n \n\" I've tried a few sleep apps and feel that Sleep Machine is the best for me. I enjoy the various quality sounds and the ability to combine them to fit my mood. It's even good just to unwind with for a few minutes. Very soothing! \"\n \n\" I love this app! combining different sounds gives you an experience that you can't get from traditional, more expensive sound machine. also, I love that you can save your combinations! and, you can set a timer and then it just goes off. fan-friggin-tastic! buy this! \"\n\n\" This is a great little app. I especially like the ability to mix sounds, each with their own level control. I use it quite a bit because it's very good for masking noise at any time of the day. \"\n\nDownload Sleep Machine ® today, and change your life overnight with a deep restorative sleep!","facts":{"developer_id":319106694,"developer_url":"http://www.sleepsoftllc.com","first_released":"2009-07-20T06:01:37Z","support_url":null,"privacy_url":null,"website_url":null,"app_version":"5.1","release_notes":"- New added sounds including: Whole House Fan ( great recording of a Whole House fan cooling a house on a warm summer night ) and Rain On Skylight ( change the pitch and volume and it sounds like rain hitting different types of windows ! ) \n- We’ve also fixed some bug issues.","rating_current_version":4.73271,"rating_count_current_version":3008,"star_counts":null,"genres":["Health & Fitness"],"languages":["EN"],"content_advisories":null,"device_families":null,"chart":null},"freshness":{"apple_read_at":"2026-10-19T06:31:11.808Z","catalog_read_at":null,"reviews_checked_at":null,"summary_written_at":null,"placed_at":"2026-10-15T06:33:53.111Z","scored_at":"2026-10-20T18:30:14.630Z"},"editorial":null,"memberships":[{"list":"white-noise","list_name":"white noise","list_status":"active","list_url":"https://apptierlist.com/best/white-noise/","position":35,"tier":"C","score":62.3,"components":{"rating":94.8,"votes":75.1,"rank":79.4,"recency":0},"status":"active","review_status":"checked","list_ranking_status":"ranked","confidence":"normal","judged_at":"2026-10-15T06:33:53.111Z"},{"list":"sleep-sounds","list_name":"sleep sounds","list_status":"active","list_url":"https://apptierlist.com/best/sleep-sounds/","position":79,"tier":null,"score":55,"components":{"rating":94.8,"votes":75.1,"rank":50.2,"recency":0},"status":"active","review_status":"checked","list_ranking_status":"ranked","confidence":"normal","judged_at":"2026-10-15T06:33:53.111Z"},{"list":"sleep-improvement","list_name":"sleep improvement","list_status":"active","list_url":"https://apptierlist.com/best/sleep-improvement/","position":145,"tier":null,"score":53.3,"components":{"rating":94.8,"votes":75.1,"rank":43.4,"recency":0},"status":"active","review_status":"checked","list_ranking_status":"ranked","confidence":"normal","judged_at":"2026-10-15T06:33:53.111Z"}],"main_list":"white-noise","claim":{"status":"none","verified":false,"site_url":null,"verified_via":null,"verified_domain":null},"history":[{"id":139418,"at":"2026-10-17T03:52:13.386Z","kind":"tier_changed","list":"white-noise","app_store_id":323061162,"app":"sleep-machine-323061162","from":"D","to":"C","reason":"score 59.9 to 62.4","job":"rescore"},{"id":98908,"at":"2026-10-15T07:28:36.151Z","kind":"tier_changed","list":"white-noise","app_store_id":323061162,"app":"sleep-machine-323061162","from":null,"to":"D","reason":"score 62.4","job":"rescore"},{"id":95514,"at":"2026-10-15T06:33:53.111Z","kind":"membership_added","list":"white-noise","app_store_id":323061162,"app":"sleep-machine-323061162","from":null,"to":"active","reason":"It is billed as a customizable white noise app with fan, furnace and low-frequency sounds that block unwanted noise and help with sleep.","job":"shadow"},{"id":95513,"at":"2026-10-15T06:33:53.111Z","kind":"membership_added","list":"sleep-sounds","app_store_id":323061162,"app":"sleep-machine-323061162","from":null,"to":"active","reason":"Its core job is mixing ambient sounds such as rain, fan and beach to help people fall asleep and stay asleep.","job":"shadow"},{"id":95512,"at":"2026-10-15T06:33:53.111Z","kind":"membership_added","list":"sleep-improvement","app_store_id":323061162,"app":"sleep-machine-323061162","from":null,"to":"active","reason":"secondary","job":"shadow"},{"id":61346,"at":"2026-10-12T02:39:57.540Z","kind":"app_added","list":null,"app_store_id":323061162,"app":"sleep-machine-323061162","from":null,"to":null,"reason":"discovered","job":"listTurn"}],"explain":{"method":"Membership is decided by a model judging the App Store listing against the list's definition (and its excludes, for memberships placed or rechecked since they were added to the prompt);
