User Reviews

Users praise the app for an easy, readable interface and its usefulness for daily and work-related Julian dates, especially with Apple Watch integration and a helpful notification badge. However, reliability on the Apple Watch is a recurring issue: watch complications often don't update, can lag or show the wrong date compared to the phone, and some reviews suggest the app is not actively maintained. Some users also miss widget functionality. Overall, it’s valuable for on-the-go Julian date checks, but watch reliability and maintenance concerns limit its usefulness.

Pros

Easy to read, simple interface for checking Julian dates.
Useful for work and daily use with reliable phone accuracy.
Apple Watch compatibility provides quick access and a game-changing experience.
Notification badge shows the current Julian day without opening the app.
Generally helpful for military/logistics work that relies on Julian dates.

Cons

Apple Watch complication often fails to update or lags behind, showing an incorrect date.
Date on the watch can be off by days or not match the phone's Julian date.
Perceived lack of ongoing support/maintenance; reviews describe it as abandoned and hard to contact the developer.
Widget/complication functionality is degraded or not working; some users report it no longer functions.
Inconsistent update behavior requiring refetching or re-adding to the watch to refresh.

Recent reviews

Consider live julian date on app icon so it is quickly visible. Like the apple clock, you can see without opening app. Icon shows 330 jd.

I saw a lot of mixed reviews on this but decided to give it a try for myself. I'm an Air Force pilot and use the Julian date to verify the currency of maintenance when doing my preflight. Having today's Julian date on my Apple Watch face is a total game changer. Thank you for the work you put into this app!
