Instead of one combined sleep score, Sleepcraft gives each phase its own score — deep, REM, light, continuity, and regularity — so you know exactly what's working and what isn't.\n\nScoring is calibrated to your age and sex. A 50-year-old man and a 25-year-old woman have different optimal deep sleep and WASO targets, based on clinical benchmarks from the NIH, CDC, and NHS.\n\nYou can tag daily factors like late coffee, alcohol, or a hard workout and see how they affect not just your overall sleep, but each individual stage. Some patterns aren't obvious — for some people, ovulation can increase deep sleep, or a daytime nap might actually extend total sleep duration rather than shorten it. Sleepcraft surfaces these personal links so you're not guessing.\n\nIt also connects your daytime active energy and HRV to nightly recovery, and uses your historical data to forecast tonight's sleep quality based on your current trends.\n\nAll processing happens on your iPhone. No backend servers, no accounts. Your tagged factors and ratings sync through your own iCloud.\n\nTerms of Use (EULA): https://sleepcraft.app/privacy","facts":{"developer_id":929517436,"developer_url":"https://sleepcraft.app","first_released":"2026-01-14T08:00:00Z","support_url":"https://sleepcraft.app/","privacy_url":"https://sleepcraft.app/privacy","website_url":"https://sleepcraft.app/","app_version":"1.5.6","release_notes":"Minor fixes","rating_current_version":4.96552,"rating_count_current_version":29,"star_counts":[0,0,0,1,28],"genres":["Health & Fitness","Medical"],"languages":["EN","FR","DE","IT","JA","KO","PL","PT","RU","ZH","ES","ZH","TR","VI"],"content_advisories":["Infrequent/Mild Medical/Treatment Information"],"device_families":["watch","iphone"],"chart":null},"freshness":{"apple_read_at":"2026-10-20T04:29:11.528Z","catalog_read_at":"2026-10-11T02:24:56.109Z","reviews_checked_at":null,"summary_written_at":"2026-10-12T07:23:53.231Z","placed_at":"2026-10-12T00:51:07.217Z","scored_at":"2026-10-21T04:04:12.785Z"},"editorial":{"one_liner":"Reads Apple Health sleep data and gives separate scores for deep, REM, light, continuity and regularity by age and sex.","what_is":"Sleepcraft reads sleep data from Apple Health and shows deep, REM, light and awake periods on a 12-hour clock face.
