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.
