It's ok, just a few things


It's great, how it supports all around the world, but in the calculate time, it's in city's and most of them have the same time zone. It would be easier to have it in states/regions instead.

Excellent App and support


I support sites in Europe, Asia, Latin America, Caribbean and USA. This application help me to know the time at each location for every conference and system maintenance. God bless you.

Very Useful App


Purchase it for use of conference calls. Excellent app. Simple and easy to use. Got all the Europe and Southeast Asia cities that I need. Thank you!
