With the exception of Google produced apps, Android device users commonly find apps becoming available for iOS (iPhone/iPad) first and then having it trickle down to them. Here’s a case, however, where Groupon (the group coupon service) made their Android app available way back July 2010 and released their iPad app just a few days ago.

The new iPad app lets you buy deals, access your purchased Groupons, find the ones that are nearby, and redeem them electronically. Deals are available in over 170 cities in the U.S. and Canada.
Groupon’s iPhone app has been available prior to the release of the iPad version. It is currently at version 220.127.116.11.
