## What is Unbuzz?

Track caffeine without turning it into a medical score.

Unbuzz is a caffeine log and timing calculator. Log coffee, tea, energy drinks and more, then follow an estimated caffeine curve and see a practical coffee cutoff based on your schedule.

LOG DRINKS FAST
• Browse an offline library of 190+ real drinks from familiar brands
• Save favourites and log them from your dashboard in one tap
• Scan barcodes or create a custom drink
• Keep a clear history of what you logged and when

FOLLOW THE TIMELINE
• See an estimate of caffeine remaining over time using a transparent half-life model
• View your estimated coffee cutoff and sleep-ready time at a glance
• Compare recent days and notice the routines you are building
• Use Apple Watch, widgets, reminders and quick actions to keep logging simple

BUILD A ROUTINE
• Choose a daily caffeine target that fits your own goals
• Try lightweight challenges focused on timing and consistency
• Review trends without pass-or-fail labels or medical conclusions

HOW THE ESTIMATE WORKS
Unbuzz applies a simplified model to the drink amounts and times you log. The curve and cutoff are estimates, not direct measurements, medical advice or a diagnosis. Individual response to caffeine varies.

PRIVATE BY DESIGN
The core calculations run on your device. Analytics are optional and off by default. There are no ads and no sale of personal data.

## Version history (last 5 releases)

### 1.4.0 — 2026-08-28

Review prompts now wait until you have logged drinks across several days, giving you time to properly experience Unbuzz first.

### 1.3.0 — 2026-07-03

New in 1.3.0

• Browse brands: an offline library of 190+ real drinks from Starbucks, Dunkin', Red Bull, Monster and more. Find your usual and log its exact caffeine in a tap.
• Favorites: tap the heart on any brand drink to save it, then log it in one tap from your dashboard.
• Faster logging: your caffeine curve updates the instant you tap.

### 1.2.1 — 2026-06-26

Stability improvements and under-the-hood polish to keep your caffeine and sleep tracking smooth. Thanks for using Unbuzz.

### 1.2.0 — 2026-06-18

• Added a personalized smart caffeine cutoff time that adapts to your sleep schedule, now shown directly on your caffeine graph.
• Fixed an issue where the caffeine cutoff could calculate incorrectly due to timezone handling.
• Fixed a layout issue where the milligrams pill on the dashboard would overlap on smaller iPhones.

### 1.1.0 — 2026-05-29

New in 1.1.0
• Personalized caffeine half-life: a short questionnaire calibrates your sleep-ready timing from how your body actually clears caffeine (smoking, hormonal factors, sensitivity), instead of a one-size-fits-all average.
• A finer half-life dial: fine-tune your personal value in 0.1-hour steps, replacing the old three-bucket setting.
• In-app What's New, so you never miss an update.
• A smoother, faster onboarding tour.
