Help with Cafade.

Logging a drink

Tap Log caffeine on Today, choose a catalog item, adjust the serving if needed, and save. For a product that is not listed, use Custom drink and enter the caffeine amount from its label or ingredient panel.

Cafade keeps the amount you entered visible as an estimate. Product values can vary by recipe, size, preparation, and region.

Editing or deleting an entry

Open History, select the entry, and choose Edit or Delete. The remaining-caffeine curve updates from the entries that remain in your log.

How the estimate works

Cafade uses a simple half-life model. Each half-life reduces the estimated amount by half. This is a personal tracking estimate, not a measurement of blood caffeine and not medical advice.

The model and its assumptions are available inside the app under Settings.

HealthKit

HealthKit is optional. In the first release, Cafade can write your chosen entries as Dietary Caffeine. The app does not need HealthKit permission to work, and the first release does not read sleep data.

If you deny permission, your in-app log and manual bedtime setting continue to work.

Cafade Pro and Restore

Cafade Pro unlocks longer history, weekly patterns, sleep comparison, and what-if previews. Purchases are made through Apple and managed in the app with RevenueCat.

To restore an eligible purchase, open Settings and choose Restore Purchases. If the product list does not load or a purchase fails, check your App Store connection and try again.
