Help with Cafade.

Logging a drink

Tap the + button on Today. A Suggested or Recent item is logged immediately at the current time; use Undo if you tapped the wrong item. Search for a drink when you want to review its size, quantity, or consumed time before saving.

For a product that is not listed, use Custom drink and enter the caffeine amount from its label, supplement panel, or medicine facts box.

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. To change a denied permission, enable Dietary Caffeine for Cafade in Apple Health, then return to Cafade and choose Connect Apple Health in Settings.

After connecting, choose Sync saved entries to retry any Cafade records that did not reach Health. Choose Stop saving new entries to pause future Health writes. Pausing does not remove existing samples; choose Resume Apple Health to sync again.

If a Health copy could not be removed after you delete an entry, Settings shows a pending-cleanup action so you can retry without restoring the local entry.

Sharing a card

Open Share from Today to preview an image of that day’s estimate, curve, total logged amount, and recent drinks. Share opens the iOS share sheet. Save Image asks only for permission to add the card to Photos.

Exporting or deleting your data

Settings can export a readable JSON copy of your local log. Delete all data removes Cafade’s local entries and settings, then attempts to remove samples that Cafade wrote to Apple Health.

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.
