Jargon is a fully offline reader for the Jargon File โ 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 lookups kept handy * Tap any cross-referenced term to jump straight to it * Share or copy any definition * Favorite entries for quick access later * "Surprise me" with a random entry โ or long-press the app icon for one * A Word of the Day widget for the Home Screen and Lock Screen * Find entries straight from Spotlight, or ask Siri to look up a term * On iPad, browse the list and read entries side by side Zero permissions. Zero network access, ever โ the dictionary ships inside the app, favorites stay on your device, nothing is ever sent anywhere. No accounts, no ads, no analytics.

Verdict
The clearest difference is in-app purchases: Jargon at none against AWS MLS's 3. Jargon also leads on ads (none vs shown) and update cadence (monthly vs every 5 months). On price and device support there is nothing between them.
