Definition

Looking up a constant, a statute, or a word should not require an account to read one page. Reference apps are dictionaries, unit tables, field manuals, and offline encyclopaedias. Education is a course; Books is a narrative; News is today's edition. The test is whether the entry cites something and whether the pack downloads. User-edited wikis go stale in public. If the app is a thin wrapper around a website, it will fail in a basement. Revision dates on an entry are part of the answer.

Common tasks

Look up a word, unit or statute without opening a browser
Download a pack for a field trip or a flight
Cite a source or a revision date on an entry
Search inside a manual you already paid for

Common constraints

User-edited entries go stale
Legal and medical texts may be incomplete for your region
Website wrappers die offline
