If you’re looking for an alternative to CoTweet, Twinterface should be your next stop. Managing multiple accounts for one brand can be a hassle that Twinterface solves. By enabling you to add subusers to your company’s Twitter account, Twinterface makes it easier to manage and navigate multiple accounts in one client.
We recommend Twinterface for small businesses and small business owners with a team of people managing Twitter points of contact. It features of most of the standard Twitter features. They also have a new user interface (UI) coming soon.
