Caff Conscious: Caffeine Log

A private caffeine tracker and caffeine log for planning around bedtime. Finished your coffee? Its caffeine isn't done yet. Caff Conscious uses the drinks you log to estimate how much caffeine could still be active at bedtime. Before your next cup, see what's still with you. Today shows your estimated active caffeine now and at the bedtime you set. The estimate uses a caffeine half-life model. It is a planning aid, not a measurement, medical advice, or a promise about sleep. Each log shows the drink, serving, caffeine amount and its source, the time, and whether you drank it at once or sipped it over time. When exact data is missing, the estimate is labeled. Your usual drinks, manual entry, saving a drink for later, edit, undo, recovery when a log needs attention, and basic watch logging are free. Pro is optional. It adds Weekly Insights, longer history, comparisons with health patterns, taper planning, and report export. Logging is not behind the paywall. Wear OS Caff Conscious includes a Wear OS companion: - Quick log from your wrist - Caffeine tile with active caffeine and daily total - Active caffeine complication - Active Sipping progress from your wrist - Caffeine cutoff complication for Pro users Your caffeine log and health information are stored on your device. Search terms or barcodes are sent when you look up a drink in the catalog. Purchases use an app-scoped identifier and receipt data. Optional diagnostics and general product analytics follow your in-app setting. Telemetry about logging reliability is turned off in released versions. Log coffee, tea, soda, energy drinks, and your own drinks. Plan caffeine around bedtime with active-caffeine estimates, a half-life curve, a daily limit, and Wear OS tools.
