Caff Conscious: Caffeine Log

Check before your next coffee. Caff Conscious is a private caffeine tracker that helps you log drinks, estimate active caffeine, and see whether today’s caffeine may still be active at your target bedtime.

Log coffee, tea, soda, energy drinks, and custom drinks in seconds. Search 7,800+ drinks and 24,000+ serving sizes, scan a barcode, tap a favorite, reuse a recent drink, or enter your own custom serving. For drinks you enjoy slowly, Start Sipping spreads the caffeine over the time you actually drink it instead of dropping the full amount into your day all at once.

The dashboard turns each log into a practical timing check. See your current active caffeine estimate, daily total, estimated clear time, and bedtime cutoff at a glance. The live half-life curve shows how your level is projected to fade hour by hour, so you can make the next coffee decision with context instead of guessing.

If sleep timing matters to you, set a target bedtime and let Caff Conscious show whether today’s caffeine may still be active then. Sleep Cutoff surfaces frame this as an estimate and a planning aid, not medical advice or a sleep guarantee. Optional reminders can help you notice your cutoff window before the day gets away from you.

Caff Conscious works across the places you log. Use Home Screen widgets, Apple Watch quick log, and watch complications to keep active caffeine visible without digging through the app. Pro users can add deeper glanceable cutoff surfaces, longer history, taper planning, weekly insights, and report exports.

Apple Health support lets you write caffeine entries and compare caffeine timing with sleep, resting heart rate, and HRV trends. These comparisons are designed for pattern discovery, not diagnosis or causal proof.

Built with privacy in mind, Caff Conscious has no ads and does not sell your health data or use it for advertising. Your caffeine logs and Apple Health information stay on your device and in your own iCloud backup — never on our servers. The app uses privacy-safe analytics and crash diagnostics to improve reliability, but it does not send caffeine amounts, drink names, sleep values, heart data, or Apple Health data for analytics.

Caff Conscious is ideal for anyone who wants a faster caffeine log, a clearer active-caffeine estimate, and a practical way to plan caffeine around bedtime. Estimates are based on caffeine half-life and are not medical advice.
