We report a 25\u2010year\u2010old Taiwanese male experiencing episodes of sleep exceeding 15\u2009h per day. Using Rhythm, a validated smartphone app that tracks human\u2010smartphone interactions, we monitored his sleep\u2013wake patterns and functional changes. Inactivity during episodes and progressively structured usage during recovery reflected clinical states. Interdaily stability, a circadian rhythm metric (range: 0\u20131), improved from low values during episodes to &gt;\u20090.37 upon return to full\u2010time work, indicating circadian recovery. This case illustrates how digital phenotyping can longitudinally assess functional and circadian dynamics in Kleine\u2013Levin syndrome, offering a scalable tool beyond traditional assessments.<\/jats:p>","DOI":"10.1111\/jsr.70157","type":"journal-article","created":{"date-parts":[[2025,7,21]],"date-time":"2025-07-21T07:53:07Z","timestamp":1753084387000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Monitoring
