I like the app and use it when flying. It would be great if the compilation would show the actual Zulu hour without having to tap on the app on my iWatch to see the actual Zulu time. It always shows “22Z”. Not a big deal, but just one more step when things get busy in the cockpit. It came in super handy for a flight recently though when ATC asked for a position report when I wasn’t in a radar environment. I tapped on the compilation and gave them position info with Zulu times. Also great for confirming TAF’s, METAR’s and ATIS info that are all done in Zulu time.

Needs complications!
This app is great, except it doesn’t have the one thing I needed and purchased it for: complications! See, Apple already lets you see UTC time and even includes it as a complication. But in order to see UTC or “Zulu” time in 24 hour time mode, you have to switch the entire clock to 24 hour mode. What I need to do is be able to see local time in 12 hour mode but Zulu time in 24 hour mode as a complication on the same watch face! It’s so frustrating that neither Apple includes a way to do this, and developers haven’t come up with UTC time app that has complications! And if they did, I would imagine they would inadvertently make it so that the 12/24 hour system setting dictates whether the complication displays in 12 hour or 24 hour mode, which would put me back at square one. Please make a complication for this app, and leave the time in 24 hour mode or make it an adjustable setting and not based on the system clock. Thank you!

Needs Always On Setting
Somewhat nice app. I use it for logging ham radio contacts and need to glance at it often. It needs to be always on when I’m operating. I imagine other users may need to use it in a way where it needs to be always on. It’s a real pain in the neck to always have to go into the general settings of your mobile device to change the Lock Screen to “never” when starting the app, then change it back when finished using it. I have an alarm clock app that has such a setting and can stay on all night. It should be quite easy to add a setting or option for this in the app. Otherwise, this would be a five star app.

Widget Doesn’t Update
The app is great, almost. The widget does not update the local time. When pressed to open the app, the local time displays correctly, but not on the Home Screen via the widget itself. Derek thanks for reaching out but the links to contact you directly are broken (Not Found message). On the widget the local time remains in the previous time zone I was in. It doesn’t update if I just switch in and out of Airplane Mode. If I restart my phone the local time will update. Again, even if the widget doesn’t update, if I open the app the local time is correct. This is only an issue with the local time. Zulu time is correct. I’m running Version 3.5 on iPhone 8 iOS 14.2. Hope this helps.

Hi love to app very useful. Only complaint is on the Apple Watch you swapped the placement of ZuluTime. On my iPhone it displays Zulu above local time in dashboard it’s the same but when I open the app on Apple Watch it’s local time on top and Zulu below after the update. Please update so it’s Zulu above local time like it was and matches the iPhone app. Please. *update: Thank you Derek for listening to your customers and updating and making fixes to your app in a timely manner. Love your app very useful.

Excellent APP, uninstall and reinstall new version!
I love this App, but must say that the complication on the watch was not updating. I read the developer’s response to a user comment about the same. I decided to uninstall the app on my iPhone which uninstalled it form the watch, and then subsequently reinstalled. This fixed the problem. The complication now always show the current Zulu time without having to tap it. Hope this helps someone!

Does not show minutes on watch complication
The phone app works fine, and the watch complication shows the current hour in Zulu time. However, it does not show minutes which makes the watch complication too imprecise for things like aviation. Edit: this is due to limitations in the watchOS API.

Does what it says, but needs complication
For 99 cents the app is ok. Would be worth more and reviewed higher if it could be used as a complication rather than just an app and agree Zulu should be in 24 hour format. Developer mentioned this is difficult to do and keep clock accurate but I rarely need a real time count of the seconds. Make the complication by creating your own time digits, drop the seconds so update once a minute, and options for 12/24 format on local and/or Zulu

iWatch Complication Still Shows Hours Only
An older review noted that the iWatch complication show only 22Z (for example) instead of full hours and minutes (like 2215Z, for example). The developer response indicated that this was fixed, which is why I purchased the app. I may be doing something wrong, but I can not get the iWatch complication to show more than just hours in Zulu time.

complication doesn’t show time all the time..?
I love the app and using the complication on my iwatch but part of the day It does not show the time. I think it has to do with the font. I hope you can fix it. it seems to involve the zero and two. it seems to show all the times that begin with a one. Thanks for looking into it.

Good for aviation
Very useful for aviators. Sometimes the conversion to/from local along with 24 hour time can get confusing with everything else going on. While not fond of the new Apple Watch widgets in general this app would be a good use since all relevant info could be displayed in the widget without accessing the app.

Awesome App!
Now I can convert time zones to Zulu time in a snap. It has a very nice and intuitive interface. The only thing I wish it had was another button at the bottom that showed you a US map with time zone divisions to show which time zone each state is in.

Widget on watch face doesn’t update
I can’t ever get the small widget on the infograph modular watch face to show the right time. For example it says 17Z now but when I tap it, it shows the correct Zulu time of 20:13. This is an Apple Watch 4 and an iPhone 11 Pro Max running iOS 13.3. Watch os is 6.1.1. Support page has no “submit” or send button or I’d have sent this information privately rather than through a review.

5 Stars ! Best of its kind ! Great Interface !
ZuluTime is fully customizable and automatically syncs and displays the correct time in ZULU according to location chosen. In addition, you may choose the arrangement of multiple ZULU TIME clocks and manually calibrate the UTC of that location.

Disappointed - Beware
In my Apple7 I applied this app only to discover it does not readily display the actual ZULU time in the display of my watch. What it shows is “21Z Zulu time”. Well, that’s not really helpful for me at all. I have to push the stem in to change the display to the actual ZULU time, in hours and minutes with seconds. Not a time or “hand use saver” nor “attention saver”. It takes more than simply gazing at the watchface and scanning it in one eye movement to gain the needed information. Granted, I’m not a pilot. But, as a licensed shortwave operator, There are times multiple calls are incoming as fast or faster than I can document them . I just want the real time.

Simple and to the point!
Very simple and straightforward.. the way I like it!! This may be a silly question and excuse my newness to the Apple Watch, but can I set your app as one of my watch faces or do I have to launch the app every time from my watch?

Difficult to set with Daylight Saving Time
Downloaded it, tried to set the offset, put in the -4 hours I needed and app kept defaulting to -5 hours. Probably an excellent app when DST is not in place.

Apple Watch Complications
This app is extremely useful for me. However, what would improve its experience for me would be the addition of complications for the Apple Watch so that the offset time you set in the app can be displayed on the watch face. Other than that, it’s great!

Loss of time
Having problems on my Apple Watch. Every two or three day Z time looses its time and gradually reverts to local time? I have to reset Z time each time thru the iPhone app to get Z time back on my watch. Is this a common problem? Please help Tried to contact support wrote the above and there is no way to send comment? Please fix loss of time on Apple Watch. It’s been several months now since you said you would look into it.

If one does celestial navigation with a sextant, one needs accurate time at the Greenwich meridian in order to determine longitude.

Complication not updating
Zulu time displays properly on the phone, but it doesn’t update properly in the watch complication. If you change complications, and then go back to the Zulu complication it show correct time, but eventually it stops updating. Needs to be fixed!
