Sleep Diary

Sleep clinics still track patient data on paper.

Sleep clinics still track patient data manually. Built the full clinical scoring engine and got it piloted by a real clinic, not a mockup. I was handed a paper sleep diary to fill out by hand, and it was obvious how much better that process could be. My PWA implements the CSD-M clinical instrument, computing TST, TIB, sleep efficiency, and WASO, with clinician-ready PDF export and cron-based push reminders.
