User Reviews

Julian Date is a simple, dependable tool for converting between calendar and Julian dates and for counting days, widely used across industries. It’s fast and easy to use, with a clean interface. However, users raise concerns about the pricing model (unexpected in-app purchases and monthly charges) and the absence of Apple Watch support or complications.

Pros

Easy to use with a clean, simple interface that makes Julian dates quick to interpret.
Bidirectional date conversion between calendar dates and Julian dates, plus the ability to count days from the start of the year.
Practical across many industries (aviation, QA, manufacturing, software) for date codes, lot tracking, and due-date calculations.
Reliable and dependable—does exactly what it’s designed to do.

Cons

Pricing and in-app purchases: users report unexpected charges (monthly fees) and taps triggering purchases, with unclear pricing.
Lack of Apple Watch support: multiple reviews express a desire for an Apple Watch complication or watch app.

I have been using this app for years it has made my work so easy i don’t have to look at the calendars. Not sure why the app was removed from the app store but good to see its back again.
