Caffeine Tracker: Better Sleep

Track coffee, tea, matcha, or energy drinks and see your estimated caffeine at bedtime. Log quickly from iPhone, Apple Watch, or the Home Screen widget.

Caffeine Tracker is a coffee-intake and sleep-planning app for iPhone and Apple Watch. Log coffee, espresso, tea, matcha, or energy drinks, see your estimated active caffeine now, and forecast what may remain at bedtime.

Plan your next caffeine decision with tonight's sleep in mind. The app compares your bedtime forecast with a target you choose and shows whether another familiar drink fits.

Features:

• A bedtime forecast with clear On track, Near target, and Above target states
• Calm next-drink guidance based on your chosen bedtime target
• Fast logging from iPhone, Apple Watch, and interactive Home Screen widgets
• Searchable coffee, tea, matcha, and energy-drink library
• Usual drinks, favorites, serving sizes, and exact-milligram entry
• A short rhythm setup using familiar questions instead of technical settings
• Adjustable caffeine response, usual sleep time, and bedtime leftover target
• A transparent caffeine-decay curve with the formula available in Settings
• Home Screen, Lock Screen, and Apple Watch complications for quick glances
• On-device caffeine history and preferences

The iPhone is the planning surface, Apple Watch makes logging quick, and widgets keep the bedtime forecast visible without opening the app.

Estimates are for planning only. Caffeine Tracker does not measure caffeine in your body or guarantee sleep quality. Individual caffeine response varies, and the app is not medical advice.
