Imagine this. Let's say you and your colleagues are trying to schedule a meeting. You are in New York and your colleagues are in London, Singapore, Mumbai and Dubai. You suggest 10am New York time for the meeting. Your colleagues can figure out the meeting time in their timezone easily. But let's say your colleague suggests 9am London time. Everyone can figure out the meeting time in their respective timezones. So far this is not too bad. But what if your colleagues in London and Dubai and Singapore suggest different times for the meeting? All of a sudden figuring out the time for each of the cities becomes a challenge. MeetWhen App to the rescue. You can add multiple cities with their respective timezone in this app. By simply changing the time in any of the timezones, the rest of the clocks adjust to show the time in their cities. This way one can easily see the time in all the cities at a glance and quickly agree on the best time for the meeting. MeetWhen is simple to use and allows one to quickly see the time in other cities if one changes the time in any of the cities.
