Yes. After you download content, practice questions, explanations, quick-reference rule summaries, and your local performance data work offline. You need a connection for the initial install and updates.
The Rules library includes quick reference summaries for 30+ topics (not full code books), such as ASCE 7, ACI 318, IBC, ASME, IEEE, NFPA, OSHA, EPA, and others. Summaries are meant for study and lookup in the app, not as a substitute for official standards on the job or in the exam room.
