Description

Jargon is a fully offline reader for the Jargon File — the hacker culture
dictionary that gave the word "hacker" its original meaning, decades before
it came to mean "cracker." Compiled by Eric S. Raymond and Guy L. Steele and
continued today as a community project, it's the closest thing hacking has
to an etymology.

Over 2,300 entries, all bundled in the app:

* Browse alphabetically with a fast-scroll index
* Instant search across terms and definitions, with your recent searches remembered
* Tap any cross-referenced term to jump straight to it
* Share or copy a definition to paste anywhere
* Favorite entries for quick access later
* "Surprise me" with a random entry — or long-press the app icon to jump straight to one

Zero permissions. Zero network access, ever — the dictionary ships inside
the app, favorites stay on your device, nothing is ever sent anywhere.
No accounts, no ads, no analytics.

Dictionary content is CC BY-SA 4.0 from the Jargon File community edition
(github.com/agiacalone/jargonfile). App source is GPL-3.0.

What’s new (1.1.0)

Share or copy any definition straight from the entry screen.
Long-press the app icon for a shortcut to a random entry.
Search now remembers your recent lookups and filters without the jitter.
