ClearHalf: Caffeine Tracker

Ever lie awake wondering if that 4pm coffee is still working? ClearHalf is a caffeine tracker that helps you see how coffee, tea, energy drinks, and alcohol may change over time — so you can better plan around sleep, bedtime, and your day. Log a drink and ClearHalf turns it into a visual Body Clock: an hour-by-hour estimate of how much may still be in your system and when it is expected to clear. PLAN YOUR CAFFEINE AROUND SLEEP Set your usual bedtime and see whether a late coffee may still be active when you're ready to sleep. ClearHalf helps you answer questions like: • Is my afternoon coffee still in my system? • When should I have my last coffee? • How much caffeine may be left by bedtime? • When is my caffeine expected to clear? YOUR BODY CLOCK See caffeine and alcohol change over time on one simple timeline. Instead of just counting milligrams, ClearHalf shows an estimated clearance curve so you can understand what may still be active now — and what it could look like hours from now. PERSONALIZED CAFFEINE ESTIMATES Caffeine affects everyone differently. With ClearHalf Premium, calibration uses your feedback to personalize future estimates instead of relying only on a standard average. SEE IT EVERYWHERE • Home Screen and Lock Screen widgets keep your Body Clock a glance away. • Apple Watch lets you quickly log drinks and check your current estimate from your wrist. • Watch complications keep key information close at hand. • Live Activities can show your estimated clear time directly on your Lock Screen. COFFEE, TEA, ENERGY DRINKS & MORE Quickly log common sources of caffeine, including coffee, espresso, tea, and energy drinks. You can also track alcoholic drinks and view their estimated clearance separately. INSIGHTS THAT ADD UP Look back at your habits, spot patterns, and experiment with your timing. What happens if you stop caffeine at 2pm instead of 4pm? How often are you reaching bedtime with caffeine still estimated to be active? ClearHalf helps turn those questions into something you can actually see. PRIVATE BY DESIGN Your logs stay on your device. ClearHalf doesn't track you or sell your data. Caffeine logs can optionally be saved to Apple Health; everything else stays with you. IMPORTANT ClearHalf provides estimates to help you understand patterns and plan your timing. Individual metabolism varies, and estimates may not reflect your actual caffeine or blood alcohol level. ClearHalf is not medical advice and should never be used as the sole basis for driving, medical, work, or other safety-critical decisions. ClearHalf Premium unlocks calibration, insights, and newest features.
