## Review summary

Users praise Horizon for its clean look and simple setup, with notable free features and the ability to use custom photos for events. However, recurring issues include widgets not auto-updating, cumbersome editing that requires deleting/recreating events, inability to manually add events, and occasional problems sharing countdown links. The app excels in design and usability but needs reliable widget syncing and more flexible event management.

### Pros

- Great aesthetic/design and vibe of the app
- Easy to set up and use
- Most features are free
- Custom photos for events / photo customization

### Cons

- Widgets do not auto-update on the home screen; you must open the app to refresh
- Editing existing events is limited and requires deleting and recreating (dates can drift)
- Cannot add events manually (missing manual entry)
- Sharing countdown links sometimes doesn’t work for others
