-- Oyez provides all the information available on the Oyez website plus the Justia Lawyer Directory & Annotated US Constitution in a conveniently package form for mobile users. -- Oyez can focus their attention to the portion of the Supreme Court’s work that most interests them. For example, a student studying constitutional law could limit the app to only those cases that would be found in any casebook or textbook. Practitioners interested in bankruptcy cases could create a collection that identifies only cases bearing on bankruptcy issues. The choice remains entirely with the user. --Users can choose between streaming or downloading audio. Streaming provides immediate access to our synchronized audio and transcripts over cellular or WiFi networks. It is robust: You can pause and pick up hours later at the same point in the audio. Downloading allows storage and later playback. We recommend its use over wifi eliminating data charges. --We have improved design and logic, including a brief tutorial to instruct old and new users on the features and functionality in the app. —Oyez will be updated regularly to account for new and old case descriptions and as the Court adds new cases to its docket.
