Read the label, log what you drink. BrewMeter is a private caffeine journal with configurable estimates. YOUR PRODUCT, YOUR PORTION Copy caffeine from your exact product label: mg per serving or mg per 100 mL. Save a custom drink, then log the volume you actually drink in mL, US fl oz or UK fl oz. See the conversion before saving. Added water does not add caffeine. Reuse favorites in one tap and undo an accidental log. A JOURNAL YOU CAN CORRECT Choose the time and serving amount, correct earlier entries, and explicitly record a caffeine-free day. Missing days stay unknown. Updating a drink’s label keeps the caffeine amounts of earlier entries. FREE DAILY TOOLS Unlimited logging, an estimated caffeine curve, the what-if simulator, widgets, Siri/Shortcuts and 30 days of history are free. The model uses your chosen half-life and caffeine threshold. It does not measure your metabolism or predict sleep. LOOK BACK WITH PRO Explore a clearly labeled 14-day example before choosing Pro. Pro adds your own 14-day intake trend, history beyond 30 days, CSV export and comparisons of recorded caffeine with sleep duration from Apple Health. These show associations, not medical conclusions. Pro is one purchase with no subscription. Existing Pro and grandfathered access remain recognized. PRIVATE BY DESIGN No account, ads or tracking. App-created records can sync through your private iCloud. Optional HealthKit access remains under your control; read sleep samples are not copied into iCloud. BrewMeter provides estimates for personal awareness, not medical advice.
