Caffeine tells you how much caffeine is in your body right now, and when it will drop low enough for you to sleep. It doesn't just add up milligrams. Every drink is absorbed slowly and then clears at your own pace, so the number climbs after a coffee, reaches a peak, and falls, the way caffeine really behaves. Last night's espresso still counts in the morning. Tap a preset to log a drink, or enter a custom amount. Had a coffee earlier and forgot? Set the time and add it.
