Downloading Twitterrific from the App Store (iOS)

There's only one version in the store for iOS! Is there still a free version with ads?

With version 5, Twitterrific is now a single, universal app that will run on the iPhone, iPad, or iPod touch. There is no longer a free version with ads in the App Store. Users who purchased the application previously should still be able to download and use version 4 from the App Store, however we are no longer actively supporting this version.
