Twitterrific has just released the next major version of their Twitter client for iPhone and iPad, version 6. The app brings many new features and improvements to the popular alternative Twitter client, as well as a new business model.
With Twitterrific 6, all features are usable for free. However, the app will feature ads and occasional prompts to upgrade. Users can upgrade to remove ads by signing up for a subscription or buying a $30 in-app Purchase.
