Digital note-taking company Evernote has just acquired Penultimate, the iPad handwriting application, according to the Cocoa Box company blog, maker of said app. Evernote has recently been in the news after raising $70 million in its fourth round of funding in a $1 billion IPO valuation, money which they say will be used to “ramp the speed of product improvements, expand internationally, and make future strategic acquisitions.” Penultimate joins the list as one of these strategic acquisitions, and no word on how much it was sold for.

Penultimate can be downloaded from the iTunes Store, and is one of the most popular apps for iPad. Users can record notes of sketches by ‘writing’ on the iPad’s screen, and the app is described as helping one to “remember everything.”

Here’s a clip of Evernote CEO Phil Libin and Penultimate founder Ben Zotto discussing the merger:

Zotto states, “Penultimate is not going away: it remains an independent application, and will continue to espouse the virtues of ease of use, elegance, and “that special something” that have kept you coming back. But I also think you’ll be thrilled, and even surprised, by how much more the app will be able to do for you as we work together to improve it and connect more profoundly with Evernote’s capabilities.”

In addition to the iPad version, Penultimate is being developed for other platforms as well.
