LastSip: Caffeine & Coffee
Coffee Log, Sleep & Half-Life
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Track caffeine in real time, see your personal half-life curve, and know the last call to still sleep tonight.
Know exactly how much caffeine is in your body — right now, and at bedtime.
LastSip logs every coffee, espresso, tea and energy drink in one tap, then uses a personalized half-life model to show your real caffeine curve — not a generic estimate. Meet Buzz Buddy, a friendly character whose mood mirrors your caffeine state in real time.

STAY IN CONTROL

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Live Activity: a live countdown to your last call on the Lock Screen and Dynamic Island, with a Stop button
• New widgets: a large Home Screen size with your clearance curve, an inline Lock Screen line, and Quick Add tiles that log a pinned drink in one tap
• Widgets and the watch complication now count down with your own half-life, so their numbers match the app
• Fixes: bedtime is handled the same everywhere, and Insights loads faster
