Verbs, the much lauded instant messaging app for iOS, is available for free in the App Store today. Verbs is a personal favorite, particularly with the recent expansion onto the iPad.
In May 2011, John Gruber had this to say:
Instant messaging app for iPhone with support for Google Talk, AIM, and MobileMe. So much better than AOL’s official AIM client it isn’t even funny. $2.99 cheap.
Free for the day? There's no excuse not to get it. Verbs is available here.
