Version 1.2.4 is intended for iPhone and iPad with iOS 15 or later. Availability depends on the App Store release.

The version described here has no in-app purchases, subscriptions or premium paywall. Store availability and any download price are determined by the store listing.

Enable reminders in the app and allow notifications in iOS Settings. Check Focus, notification previews and the event time zone. Open the app periodically to refresh scheduled reminders; iOS controls background refresh and delivery.

Choose the unknown-time option or a two-hour period. Enter a time zone carefully. Interpretations depend on your inputs and the traditional model; precision is not a prediction guarantee.

No developer cloud sync is implemented. Device backups are managed by the operating system. Copies shared to other apps are handled separately.

Use Settings → Reset app data to clear local profiles, drafts, events, history and reminders. Manage device backups and copies you shared separately.

No native iOS home-screen widget is implemented in this version. The Android widget is a separate platform feature.
