Call Checker vs World Times

In a global world it becomes more and more difficult to keep track of the local times of all your important contacts. If you want to avoid to call them at a bad time this application is for you. A quick check tells you whether it's the right time to call or not and who is available at the moment. If you enter the phone number a simple tap on the name is enough to initiate the call (iPhone only).

This app displays the time in over 400 world-wide locations as well as their Greenwich Mean Time offset. Locations are indexed and ordered alphabetically within their respective geopolitical regions. An additional page facilitates the calculation of the time difference between 2 time zones calculated from the "GMT" offsets which can be obtained from the table view page. For locations that do not display the "GMT" offset it can easily be calculated by subtracting the the "GMT" time from the local time. The app displays the day of a location relative to the day of the current time zone device setting (i.e. "Today", "Tomorrow" or "Yesterday") in 32 languages.
