## What is CaffIQ?

Love your coffee. Keep your nights.

You don't have to choose between the coffee you love and the sleep you need. CaffIQ shows you how today's coffee, tea, and energy drinks turn into tonight's sleep — and exactly how late you can still enjoy your next cup, tuned to your own body.

It was never the coffee. It's the timing.

WHAT MAKES CAFFIQ DIFFERENT

→ Tuned to YOUR body
Most caffeine apps use one-size-fits-all averages. CaffIQ adapts to your weight, age, and sensitivity for predictions that reflect how caffeine actually clears in your system.

→ See your last cup, before you pour it
A real-time readiness score tells you how late you can still enjoy a coffee and protect tonight's rest. No guesswork. No 2 a.m. ceiling-staring.

→ Track in real time, everywhere
Live Activities show your current caffeine level on the Dynamic Island and Lock Screen. Glance at Home Screen widgets. Ask Siri "When can I sleep?" — get an instant answer.

WHAT YOU GET

- Real-time caffeine modeling, personalized to your profile
- Your personal "last cup" time to protect sleep
- Live Activities (Dynamic Island + Lock Screen)
- Home Screen & Lock Screen widgets
- Siri Shortcuts for hands-free logging
- Quick-add for coffee, espresso, tea, matcha, energy drinks, soda & more
- Specialty-friendly: log single-origin, decaf, cold brew
- Daily, weekly & monthly insights
- Streaks and milestones
- Apple Health sync (caffeine + sleep)
- 5.5 MB — barely any space

GROUNDED IN RESEARCH

CaffIQ's timing is informed by peer-reviewed sleep science — translated into clear, everyday guidance (no PhD required). Caffeine's half-life varies widely from person to person, so a generic "stop at 2 p.m." rule rarely fits. CaffIQ does the math for you.

MADE FOR

→ Coffee lovers who don't want to give it up — just understand their cup
→ Busy people who want to perform by day and sleep at night
→ Anyone who feels wired or jittery and wants to stay in control
→ People keeping caffeine under a personal limit, tuned to their body
→ Anyone who's ever lain awake wondering "was it the afternoon latte?"

## Version history (last 5 releases)

### 3.3 — 2026-08-14

The personalized caffeine model joins CaffIQ Pro.
• Half-life factors — smoking, age, pregnancy, hormonal contraception and more — are now Pro, shown as a range computed from your profile, never a one-size number.
• On the free plan, the curve uses the 5-hour scientific reference. If you had set one of these factors, your Last Safe Hour moves — earlier if you smoke, later if you're 60 or over, much later during pregnancy. Notifications, widgets and streaks follow the same curve.
• The Live Activity on the Lock Screen is now part of Pro.

The chart answers your finger again.
• Scrubbing the caffeine curve follows your finger — a 3.2 regression, fixed.
• The Sleep impact gauge no longer stays empty, and the Safe Hours pills show the limit time itself, in your clock format — spelling out "Tomorrow" when that's what they mean.

Trials and purchases that answer.
• Reminders during your free trial — and the offers after it — now actually arrive.
• Purchase errors speak your language, cancelling a purchase no longer shows an error, and Restore purchases always tells you how it went — even when there is nothing to restore.

Notifications on time.
• The Bedtime check-in arrives the evening it belongs to, not a day late.
• The morning reminder skips the days you have already logged.

Also: tap anywhere on a row to pick a drink, a floating add button that stays put, Pro features explained in plain words, corrected translations and plurals, and each language listed once in iOS Settings.

### 3.2 — 2026-08-10

Apple Health, properly connected.
• Every drink you log now reaches Health — from the widget, Siri, the Control Center button, Shortcuts and Spotlight, not just from inside the app.
• Editing or deleting a drink updates Health too, so nothing gets counted twice.
• You can fill in your age and weight straight from Health.

Insights that answer on the first tap.
• The 48h and 7d buttons no longer swallow taps.
• Safe Hours now show the hour that matters — the latest time each favourite still fits your night — full-size, matching the widget.
• The sleep scatter reads against your own thresholds, and the app stops asking for sleep access you already granted.

Pro sleep thresholds, one source of truth.
• The three values shown in Pro Features are now exactly what every calculation, tooltip and estimate uses.
• If Pro ends, your thresholds return to the science defaults — your own values are kept, and come back if you resubscribe.

Also: your feedback and newsletter signup actually reach us now, calibration tells you when it's done, the widget shows all six favourites with a clear moon when a drink no longer fits today, correct plurals in all eight languages, and streak celebrations that show up the day you earn them.

### 3.1 — 2026-07-16

Love your coffee. Keep your nights.

CaffIQ goes hands-free — and gets even more personal:

• Ask Siri — "When can I sleep?", "Log a coffee", "How much caffeine do I have?" — now in all 8 languages.
• Spotlight — find and log your drinks right from search.
• Control Center — a new "Log Coffee" control to add a drink in one tap (also from the Lock Screen and Action button).
• Even more personal (Pro) — a new sleep-sensitivity factor sharpens your predictions.
• Plus polish and fixes throughout.
