CafLog vs Caffy

CafLog helps you log caffeine in seconds and see how much will still be in your body at bedtime. - Your drinks become a 3D scene Each time you log a drink, a cup, can or bottle drops from the top of the screen and piles up at the bottom. The pile resets every week, so you can see at a glance how much you've had this week. You can grab and move the drinks with your finger. - Quick logging Pick from 26 drinks, including coffee, espresso, green tea and energy drinks. Long-press the log button to bring up your favorites. Adjust the amount or time later, and add your own drinks. - Coffee-kun tells you about your sleep CafLog estimates the caffeine in your body now and what will be left at your bedtime. Coffee-kun, the app's character, sums up your day in one line. - Look back with a monthly grid Each day of the month is a square shaded by how much you had. Days without a record show as no-caffeine days. Highlights are summed up in four cards. - Rewards that grow as you go Keep logging to climb six achievement levels. Each level unlocks rewards: Coffee-kun expression icons, Coffee-kun artwork, themes for the whole app and 3D looks. - Widgets Check today's total and your bedtime estimate on the Home Screen and Lock Screen. - CafLog Pro (auto-renewing subscription) - Past records (earlier weeks in 3D and earlier months in Review) - Metabolism simulation (your caffeine curve) - Every look unlocked - Saving to Apple Health and iCloud sync - Up to 4 favorites - No ads Monthly and yearly plans are available.

Caffy shows your exact caffeine level right now, and tells you precisely when you'll be ready to sleep tonight. Using pharmacokinetic half-life models backed by FDA, EFSA & NIH research, Caffy calculates your personal caffeine curve based on your biology. WHAT MAKES CAFFY DIFFERENT: • Real-time caffeine decay curve: personalized to your age, gender & sensitivity • Sleep readiness score (0–100): know if tonight's sleep is at risk before bedtime • Focus window: see exactly when your caffeine peaks for maximum productivity • AI Weekly Analysis: AI reveals your personal caffeine patterns • Caffeine Detox Programs: structured plans to reduce dependence gradually • 6 Live Widgets: caffeine data on your Home Screen and Lock Screen • 5 Languages: English, Turkish, German, Spanish, Japanese PERSONALIZED HALF-LIFE: Your body processes caffeine differently. Caffy accounts for: • Pregnancy (9h / 12h / 18h half-life) • Oral contraceptive use (7h half-life) • Smoking status (3h half-life) • Age, gender & caffeine sensitivity SCIENCE-BACKED: Caffy's model uses the same caffeine decay formula cited by FDA, EFSA, NIH, and the Sleep Foundation. Not estimates, not averages. A 45-minute absorption phase followed by exponential decay based on your personal half-life. PRIVACY FIRST: No ads. No data selling.
