There wasn't a free, no ad, modern time converter app with no tracking... so I built one. See, and track cities by their time zone. See what time it would be in a city if it was a different time in your city. Help coordinate meetings accross time zones. If you like it, give me a review, I would appreciate it. If you want a new feature, write that in the review also.
