## What is Caffeine Mate?

Can I have another coffee and still stay within tonight’s caffeine target?

Caffeine gives coffee drinkers a useful answer before the next cup. Log coffee, espresso, tea, matcha, energy drinks, or a custom amount, then see what may remain at bedtime and whether another familiar drink fits your target.

• See your estimated caffeine now and at your chosen bedtime
• Get a clear On track, Near target, or Above target state
• Check whether your usual drink fits before you log it
• Log quickly from iPhone, Apple Watch, or an interactive widget
• Search familiar drinks, save favorites, choose a serving, or enter exact milligrams
• Tune your caffeine response, usual sleep time, and bedtime target
• Review a transparent decay curve and formula

Caffeine Pro connects what you drink with when you actually sleep. Connect Apple Health or enter sleep manually to build private, on-device patterns:

• Review each night’s saved bedtime, actual sleep, and estimated caffeine
• See how caffeine timing and sleep line up as your history grows
• See a conservative bedtime target only when enough evidence supports one
• Corrections, reversible exclusions, and guided earlier-cutoff experiments

COFFEE FIRST, EVERY CAFFEINE SOURCE COVERED

Choose from coffee, espresso, tea, matcha, energy drinks, and other popular servings. Save the drinks you actually have or log a custom caffeine amount.

PRIVATE BY DESIGN

No account. No ads. No analytics. No third-party tracking. Your caffeine history, preferences, and optional Pro sleep data stay on your devices.

Estimates and observed patterns are for planning only. Caffeine does not measure caffeine in your body, prove that caffeine caused a sleep outcome, guarantee sleep quality, or provide medical advice. Individual caffeine response varies.

### 1.3 — 2026-07-31

Version 1.3 adds a guided rhythm setup, usual drinks, and interactive Home Screen widgets. Choose how caffeine usually feels, your sleep time, and your bedtime leftover target in familiar language, then keep the resulting forecast visible from the Home Screen.

Apple Watch now leads with one bedtime estimate, one next-drink cue, and one Log caffeine action. Its drink list also matches your usual choices from iPhone.

Estimates are for planning only. Caffeine content and individual response vary.

### 1.2 — 2026-07-16

Version 1.2 adds a full iPhone experience with a searchable drink library, favorites, serving sizes, and a clearer caffeine-decay timeline in dark and light themes. The refreshed Apple Watch dashboard shows estimated active caffeine, your bedtime target, and direct guidance about whether another coffee fits. Complication visuals and update reliability are improved too.

Estimates are for planning only. Caffeine content and metabolism vary.
