Very handy for scheduling conference calls with team members around the world!
One suggestion: After choosing a time, I would like to be see more time zones without scrolling. It would be nice if the time selector dials took less space or would pop up only when you want to use them.
Also, I like the country flags when building the list of time zone to track. Too bad they dont show up on the main screen too. That would be cool and add some color!
Overall, nice job!
