## What is BrewMeter?

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.

## Version history (last 5 releases)

### 1.4.0 — 2026-08-20

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.

### 1.3.3 — 2026-08-19

BrewMeter 1.3.3 keeps the focus on your caffeine log:

- After you consult a weekly insight, a small dismissible note now lets you leave an optional tip. Tips support development and never unlock features.
- After a few logged drinks, BrewMeter may invite you once to rate it on the App Store through the standard system prompt.
- Refreshed App Store information across all supported languages.

### 1.3.2 — 2026-08-10

BrewMeter 1.3.2 makes the What If simulator clearer before you log a drink:

- Compare your current and simulated caffeine curves.
- See the estimated time to fall below your configured threshold, without implying a sleep guarantee.
- Keep simulation data on your device and separate from your real log.

### 1.3.1 — 2026-08-05

This maintenance update refreshes App Store listing details and improves release reliability. The core BrewMeter experience is unchanged.

### 1.3.0 — 2026-07-10

BrewMeter 1.3 makes daily logging faster and weekly guidance clearer:

- Create and reuse custom beverages.
- Log from the app, interactive widgets, Siri, or Shortcuts.
- Optionally adapt your caffeine cutoff from HealthKit sleep patterns, only after you confirm the change.
- Receive one evidence-based weekly priority with one action.
- Keep every core feature free, private, and available without an account.
