Useful

I have had this app for awhile. It continues to be quite useful for a variety of time related tasks and it’s easy to use.

Great App

Multi functional, converts to military time, time in another country, and age other features I have yet to explore. The cities in countries could be improved but over all useful. ie United States instead of America
