Caffeine Tracker: Coffee Sleep

Caffeine Tracker tells you how much caffeine is in your body right now and when to stop for a good night's sleep. Log a flat white, a builder's tea or a can of Monster in one tap. Caffeine Tracker models how your body clears caffeine and shows a live curve for the day, a "last drink by" time for your bedtime, and a reminder before it is too late. Connect Apple Health and see how your caffeine lines up with your sleep. On days you drink coffee late, do you sleep less? Caffeine Tracker compares your own nights and tells you in plain English.
