## What is Caffeine Intake?

Caffeine Intake helps you understand not just how much caffeine you’ve had today — but how much is still active in your system right now.

Log coffee, espresso, tea, matcha, energy drinks, soda, pre-workout, and supplements. The app estimates remaining caffeine using a half-life model, projects what’s left by bedtime, and keeps you aligned with a personal daily target.

FEATURES

• Active caffeine estimate — see what’s still processing, not only what you drank
• Bedtime projection — check estimated caffeine remaining when you plan to sleep
• Daily target — set a personal goal and track progress through the day
• Quick logging — built-in drink presets plus custom drinks and favorites
• History & trends — review past days and weekly intake
• Helpful reminders — approaching goal, large doses, late-day drinks, bedtime check-in
• Export your data — CSV or JSON anytime
• Fully private — no account, no cloud sync, no analytics; data stays on your device

PERSONALIZE IT

Choose your daily target, bedtime and wake time, caffeine half-life, and ml or fl oz. Presets are editable estimates — adjust them to match what you actually drink.

IMPORTANT

Estimates are educational and based on a standard half-life model. Individual sensitivity varies. This app is not medical advice. If you are pregnant, breastfeeding, under 18, taking medications, or managing a health condition, set limits with a qualified clinician.
