System requirements

Diem targets iOS 18.0 and later. The app can work locally without an in-app account.

Core features

Diem tracks important dates, local reminders, Home Screen widgets, photo backgrounds, and share posters.

Sync model

iCloud / CloudKit is an enhancement rather than a requirement. Without iCloud, the app can still work locally.

1. Common Issues

Notifications are not arriving

  1. Make sure Diem has notification permission in iOS Settings.
  2. Confirm the event reminder is enabled and the reminder time is correct.
  3. Check whether Focus mode or system notification restrictions are blocking alerts.

Widgets are not updating

  1. Confirm the event was saved successfully.
  2. Try removing and re-adding the widget, or wait for iOS to refresh timelines.
  3. After changing language, appearance, or event data, allow the system a short time to reload the widget timeline.

Photo backgrounds are unavailable

  1. Make sure Diem has permission to access your photo library.
  2. Reopen the editor and confirm the selected image is still available locally.
  3. If exporting fails, confirm photo library add permission or use the system share sheet instead.

iCloud / CloudKit sync does not appear to work

  1. Make sure the device is signed in to iCloud and CloudKit is available.
  2. Check your network connection.
  3. If no iCloud account is available, Diem will continue to work locally.

2. Contact

If the steps above do not solve your issue, contact the publisher and include as much useful context as possible.
