Caffeine Tracker: Daily Log Live

A calm caffeine log for fast drink tracking, active caffeine estimates, and a clearer bedtime cutoff. Caffeine Tracker helps you log coffee, tea, energy drinks, soda, pre-workout, and custom caffeine amounts in a few seconds. Instead of only counting today's total, it shows how much caffeine may still be active in your system and when it is likely to clear. Use it as a practical caffeine tracker for daily timing: - Build a quick caffeine log with common drinks, recent drinks, and custom mg amounts - See a live active-caffeine curve across the day - Check likely clear time and bedtime cutoff context - Preview whether another standard drink may stay active near bedtime - Track caffeine intake against your personal daily limit - Review history, weekly insights, and 30-day timing patterns - Use the Android home screen widget for a compact caffeine snapshot - Use the Wear OS companion for quick coffee and espresso access from your wrist Caffeine Tracker is designed for repeat daily use. Log an espresso, coffee, energy drink, tea, matcha, soda, or pre-workout, then return later to see your active caffeine level, daily caffeine limit progress, and likely clear time. The app also works as a simple caffeine counter and caffeine calculator for people who care about timing, not just totals. The caffeine half-life model is informational and approximate, with settings for bedtime, wake time, daily limit, and personalization. Privacy and monetization are kept simple. Core caffeine logs and settings are stored locally on your device. The app is free with ads, and an optional one-time remove-ads purchase is available. There is no subscription and no account required for core tracking. 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.
