BrewMeter - Caffeine Tracker
Your coffee cutoff for sleep
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: BrewMeter Pro — sleep correlation, full history, tolerance trends, CSV export. One purchase, no subscription. Logging, the curve and widgets stay free.
Two taps to log an espresso, one glance to know whether a 4 p.m. refill still makes sense. BrewMeter turns what you drink into a caffeine curve you can actually read — no account, no ads.
SEE YOUR CURRENT CAFFEINE
View an estimated caffeine curve based on what you log and your selected half-life. Check when the estimate falls below your caffeine threshold and decide whether another drink fits your plans.
LOG YOUR WAY
Choose from common drinks, save your own beverages, and reuse favorites. Add an entry in the app or use an interactive widget, Siri, or a Shortcut when speed matters.
PLAN WITH CONTEXT
Use the what-if simulator before adding a drink. With optional HealthKit permission, BrewMeter can compare recent sleep timing with your cutoff and suggest an adjustment. Nothing changes until you confirm it.
ONE WEEKLY PRIORITY
Get one focused, evidence-based priority each week with one practical action, based on the entries stored on your device.
FREE, WITH PRO FOR THE LONG VIEW
Everything above is free, with no time limit: unlimited logging, the caffeine curve, interactive widgets, Siri and Shortcuts, the what-if simulator, daily goals, and 30 days of history.
BrewMeter Pro adds the analysis features for digging deeper:
- Sleep correlation: compare logged caffeine with sleep duration from Apple Health
- Complete history beyond the last 30 days
- Tolerance trend charts across multiple days
- CSV export of all your entries
Pro is a single one-time purchase. There is no subscription and nothing renews. If you used BrewMeter before Pro existed, you keep every feature you already had, free, forever.
PRIVATE BY DESIGN
No ads, no tracking, and no account. Your data stays on your device and in your private iCloud storage; optional HealthKit access remains under your control.
BrewMeter provides estimates for personal awareness and is not medical advice.

Ratings & Reviews

BrewMeter 1.4.0 introduces BrewMeter Pro:
- The sleep correlation chart, history beyond 30 days, tolerance trend charts, and CSV export now form BrewMeter Pro: one purchase, no subscription, nothing renews.
- Used BrewMeter before this update? You keep every feature you already had, free, forever. The paywall only applies to new installs.
- Everything else stays free with no time limit: unlimited logging, the caffeine curve, widgets, Siri, the what-if simulator, and 30 days of history.
- The tip jar is gone. BrewMeter sells exactly one thing now, and Pro is it.
- Settings now links to more apps by the same developer.
