## What is CafLog?

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. If a plan includes a free trial, cancel at least 24 hours before it ends to avoid being charged. Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.

The free version shows ads at the bottom of the Review and Account screens. CafLog never asks to track you for ads and does not show personalized ads.

Amounts are estimates based on typical values and are not intended for medical diagnosis or treatment.
