Yup. There’s an iPhone app for the end of the world on Saturday, May 21st, 2011. For $1.99.

The app’s makers set up this website to promote it. Here is a link to the actual app on the iTunes website.

The app, essentially a cool-looking and detailed countdown clock, is called Versaries.

Normally, it just helps users mark important milestones or events.

It could be in anticipation of something – like the countdown to Super Bowl. Or, it could be tracking the time that has passed since a milestone, like “the 1 Billionth Second since you were born.”

For the ‘May 21 end of the world’ milestone on Saturday, users can enter the code “endoftheworld” to add it to their Versaries app.

When Versaries’ countdown website was accessed by IBTimes from New York, the countdown clock was set to May 21, 6 p.m. local New York time.

According to Harold Camping, a rolling earthquake will strike the world at 6 p.m. local time in each locale. However, the first earthquake will strike in New Zealand (where the sun rises first), which would mark the beginning of the end of the world.

In major global cities, New Zealand’s 6:00 p.m. local time on Saturday translates to the following local times:

Canberra, Australia: 4:00 p.m.

Tokyo, Japan: 3:00 p.m.

Beijing, China: 2:00 p.m.

New Delhi, India: 11:30 a.m.
