About this app

Check before your next coffee.

Caff Conscious is a private caffeine log and cutoff-first tracker that helps you see how much caffeine is still active, when it may clear, and whether it 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 barcodes, tap favorites, reuse recent drinks, or create your own serving. Start Sipping tracks a drink over the time you actually drink it, so caffeine is modeled over time instead of all at once.

Privacy first

No ads. We do not sell health data or use it for ads. Your caffeine logs and Health Connect data stay on your device and in your own Google backup — never on our servers.

Caff Conscious uses privacy-safe product analytics and crash diagnostics to improve the app. We do not send caffeine amounts, drink names, IDs, ad identifiers, or Health Connect data (including sleep/heart signals) in analytics.

Caff Conscious uses estimates based on caffeine half-life and is not medical advice.
