## What is Zulu Time?

An iPhone, Apple Watch and iPad app to see Local and Zulu time (GMT) or multiple time zones in a single glance. Includes Widgets for both the iPhone and Apple Watch. Useful for pilots in getting weather briefings and filing flight plans, or Ham radio operators to do timezone conversions. No more worrying about getting the timezone offset correct or Daylight Savings Time conversions. Easily convert from different time zones, including times in the future or past.

On the iPhone:

- Home and Lock Screen widgets

- The Zulu Time page gives a quick view of both Zulu and Local times

- The Offset Time page allows you to see Zulu and local time either in the future or past by entering an offset via the Offset button. Tapping either Zulu or Local times will allow you to enter a time in the future or past, synchronizing both Local and Zulu times with that offset. The offset only applies to this view (except on the iPad the offset applies to everything on the page)

- The Multiple Zones page allows you to add as many time zones as you wish in a scrolling view. Clicking on any Time Zone will allow you to change it.

on iPad:

All information is combined on one screen. You have user customizable time zones on the right hand side. On the left, you have Zulu and Local time and one customizable time zone. The offset to see future or past time can be done via the Offset button or tapping any of either the Zulu, Local or Custom time buttons on the left.

On the Watch:

Complications available in all watch faces making for glanceable ZuluTime and access to the app, which gives offset able time computation.

### 5/5 — Simple, easy, super useful

*2026-07-25, version 3.7.0*

I love this app.  Easy to use, intuitive, does everything I need it to and a few things I didn’t know I wanted until I saw it did it.

### 3/5 — day wrong on widget

*2026-06-07, version 3.7.0*

when using the full app, no issues, but the widget 'day' does not change when gmt passes 00:00.  the full app does.  doing in on iphone, ipad etc.

### 5/5 — Zulu

*2026-05-29, version 3.7.0*

A lot of international companies and our own government reference UTC,  nice to have local times and UTC on one page

### 3/5 — Wrong date

*2026-03-06, version 3.7.0*

The wedge of the app doesn’t show the correct date until you go into the app, and coming back out it still show wrong in the wedge.

### 3/5 — Wrong date in widget.

*2026-02-27, version 3.7.0*

When checking the zulu and local time in the app the zulu date will be correct, but when you have a widget set up, the Zulu time might show the wrong date. In the widget, the Zulu time will always have the same date as the local time even if the zulu time is a day ahead.

### 5/5 — very useful

*2026-01-22, version 3.7.0*

i can’t give it 5 stars because of a glitch- mountain time is displayed as the same as pacific time.  this would only be accurate in arizona which doesn’t keep dst.  otherwise a great app.

update:  glitch corrected.
can't imagine a better app!!

Watch exact time freak just want the time to the second to see the accuracy I’m getting. And I get that plus where ever I am no haggling or paying a hundred or more dollars a year.
