The long-delayed Readability iOS app will finally be available on March 1st, the company has announced. The app is being developed in tandem with Teehan+Lax, and will be a universal title with native iPad and iPhone interfaces. Users will be able to adjust options like brightness, font size, and font type, and share content via Twitter. The company is otherwise being mum on features, except to say the app's goal is just an essential set of features for reading.
