Helpful tool

I have been using iTimezone for a couple of years now and the latest version is still extremely helpful. I travel around the world for work and being able to convert a future time and date in one time zone into what time and date it will be another time zone or my home time zone is invaluable. I have found every time zone I have needed by entering the city I am in or a nearby city. It is particularly helpful in helping determine what day it will be when converting time. This comes in very handy when the international dateline is part of your travels and you can easily be off my an entire day if you miscalculate. If you ever have travel fatigue, you know that things like calculating time can get challenging and this app makes it simple.

July 2021 update:
Still glad to be using this app for my work related time conversions.

Bad app

This app doesn’t work. All I could do is compare current time with another city. No need for this as it is a standard widget with the iphone. There is no way to back test time as advertised.

Best of the lot

I used to love this app, and seemed to have lost it a while ago but this new version I just found works a treat. It’s the black belt of time zone apps. Bravo.

Doesn’t work

Major glitches with this version. This app used to work well, but now it is useless. For example, when I go to put in the time to convert, it swaps the cities around, deletes cities from my list, and add ones that weren’t there.
