Sleep Phase Tracker

SleepPT helps you follow your doctor's delayed sleep phase protocol — the gradual, week-by-week process of shifting your body clock earlier.

Set up your personalized protocol once, then let the app guide you every night with your current bedtime, wake time, melatonin reminder, and light therapy cues. Log each morning, track your streak, and advance through your schedule at your own pace.
