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.

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.
