Caffeine stays a long time
Caffeine clears very slowly for you. Even a morning cup hangs around, so timing matters more for you than almost anyone.
What this means for your day
A coffee at 2pm leaves roughly 48mg still active by 11pm, and your bedtime limit sits at about 48mg. You land exactly on the line from one cup. For you the standard 2pm cutoff is not conservative, it is the edge.
What to watch for
At this clearance rate, a morning coffee is still meaningfully present in the early evening. That means your total daily load matters as much as your last cup, and moving your cutoff earlier tends to do more for your sleep than cutting the amount.
Get your actual curve, not a bucket
This result comes from three questions. The app models your real clearance from your own logged drinks, then gives you a sleep-safe cutoff, crash forecast, and jitter threshold that update as your day goes.
