After announcing the release of the Office for iPad apps late last month, Microsoft announced today that the separate Word, Excel and PowerPoint apps for iPad have collectively reached 12 million downloads a week after release. The number also included downloads of the OneNote app for iPad, which has been available for a couple of years leading up to the release of the Office apps, but Microsoft didn’t provide a breakdown of sales by app.

It wasn’t long after release that Microsoft’s three new Office apps for iPad hit the top of the free App Store charts thanks to a ton of promotion from the announcement, decent reviews, and a nice big banner on the top of the App Store from Apple. The apps are free to download, but require a $99/year subscription to unlock full editing features.

Microsoft has been doing its own promotions for the launch too, such as handing out free Office 365 subscriptions to iPad users at retail locations.
