Exactly What You Are Looking For

Tired of standard international clock apps? Anyone can tell me what time it is NOW, but what time WILL it be there, when I’m available for that meeting here? And vice-verse.

Clean, informative, graphic interface. Does exactly what I want. Drag the time hand and see what time it will be everywhere that you care about. Perfect for setting up international meetings.

My only two quibbles:
- A toggle between standard and military time.
- An option to assign my own color choices.

But, again, quibbles. Still gets the 5 star for functionality and execution. Worth the price of admission!

Great App

Great app. Clean design. Just two features/options would make this even better (1) be able use custom labels against the cities (i.e. team names and their respective cities/office hours) which would allow to layer multiple teams even within the same city and (2) customise the color.

This would make this the perfect meeting facilator for global projects and teams.

Developer Response ,

Latest update adds ability to rename locations. Enjoy!

Great tool for travelers and global teams

I really liked the “at a glance” UI. One problem with the version I’m using: it gets confused and places the rings way below the 24-hour clock hand. A restart of the app fixes this, but it happens all the time. It needs fixing.
