Ratings and Reviews

Solid App


This needs an option to switch between 24 hour clock and AM/PM, and/or display both simultaneously. Other than that minor inconvenience is fail to find a flaw worth noting here. Good job developer, I purchased your iAP in the hopes that it aids you to add the above feature.

Nice and usefull


One thing that suggest is: when you are comparing 2 or more time zones, you have a reference that you want to compare with others. So would be good to have one of the timezone freezed while the other ones you could navigate among them. Like "freeze panes" on excel.
