Caffeine Tracker is built for people who want a practical caffeine intake tracker, caffeine counter, and caffeine calculator without a complicated account setup. Core caffeine logs and settings are stored locally on your device, and the app does not require an account or cloud sync for normal use.

The app is free with ads. The optional Remove Ads purchase is a one-time in-app product that removes banner ads and supports development. It is not a subscription and does not unlock separate premium features.

Caffeine estimates are informational. Your actual caffeine response can vary based on the drink, amount, timing, metabolism, tolerance, medications, pregnancy, and other personal factors.

Caffeine Tracker is for informational tracking only. It is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a healthcare professional for medical advice, especially if you are pregnant, sensitive to caffeine, or managing a health condition.
