Nimbus vs Jargon
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Nimbus
Read full descriptionHide full description
Nimbus started off as a personal project. I was building out SwiftUI components and wanted a clean way to organize, revisit, and reuse them. But the more I built it, the more I realized it could help other iOS devs too — especially folks learning SwiftUI. It’s a reference app that shows off SwiftUI views — animations, layouts, buttons, and more — with the actual code and a quick breakdown of what’s happening. You can browse by category, favorite the ones you like, and even add your own. Whether you’re just getting started with SwiftUI or want a place to find and share reusable components, Nimbus is open-source and always evolving. Built for learners, tinkerers, and devs who like to move fast.
Jargon

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 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 — or long-press the app icon for 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.

Verdict
Nimbus and Jargon are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
