The complete U.S. Constitution in your pocket — with biographies of every signer and rich historical context. THE FULL TEXT Read the Preamble, all seven Articles, and all 27 Amendments — including the Bill of Rights — in a clean, easy-to-read format. Each section includes editorial notes covering ratification history, key interpretations, and the context behind each clause. 55 BIOGRAPHIES Explore detailed biographies of every signer of the Constitution. Learn where they were from, the roles they played at the Constitutional Convention, and the offices they held in the new republic. KEYWORD SEARCH Basic search for words or phrases anywhere in the text. Now free for all users — use the search bar at the top of the Document or Signers list. UPGRADE FOR MORE "Constitution Explained" (optional in-app purchase) adds two study tools. “Ask about this” places common questions on every section of the Constitution — tap one to read a clear, plain-language explanation based on research by the Library of Congress. Question Search lets you type a question in your own words, like “Can the president declare war?”, and points you toward the parts your question relates to. Question Search runs entirely on your device and requires iOS 26+ with Apple Intelligence; the section explanations work on any device the app supports.* Nothing you type ever leaves your device, and no account is needed. One purchase covers both tools — no subscription and no recurring charge. Whether you're a student, a history buff, or a citizen who wants to know the law of the land, Constitution puts America's founding document at your fingertips. *Question Search uses on-device AI (Apple Intelligence) to match your question to a relevant section; all responses in this feature are educational information only, not legal advice, and may not reflect every court decision or every state's law.
