## Description

Julianator is a date converter that supports two-way conversions between Gregorian dates and Julian day-of-year numbers (ordinal date). For example, September 11, 2022 becomes 2022-254, and 2022-254 converts back to September 11, 2022.

The extension has a simple, clean UI with date pickers and a monthly view to compare both calendars at a glance.

## Review summary

Users consistently praise Julianator for its simple, clean design and practical Julian date tools. The app effectively supports quick Julian/date conversions, and allows searching by both Julian and standard dates. Hardware integrations—watch complications and a home/lock screen widget—are valued, along with an ad-free, no-nag experience and a smooth date selector. Recurrent drawbacks focus on widget reliability and icon/date display: the lock screen widget can misbehave or show truncated dates, and the home screen icon often fails to show the current Julian date. Some users also wish for updates and accuracy improvements.

### Pros

- Simple, clean design and easy-to-use interface.
- Very useful for Julian date conversion, with quick search by Julian or Gregorian date.
- Helpful hardware integrations: watch complication and iPhone widget.
- Ad-free experience with no nags and a smooth date selector.
- Clear, fast displays that make planning and scheduling straightforward.

### Cons

- Widget reliability issues on lock screen/home screen rendering (can misbehave or show truncated dates).
- Home screen icon often fails to display the current Julian date.
