Jargonaut: Dev Vocabulary

Learn coding terms daily

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Ever nodded along in a standup pretending you knew what "idempotent" meant? Jargonaut fixes that — one concept a day, explained in plain English, locked in with a quick quiz. In 3–5 minutes a day, you'll go from nodding along to leading the conversation. Each daily mission teaches one real software engineering concept with a plain definition, a real-world analogy, a sentence you'd actually hear in a PR review, and a 3-question debrief to make it stick. WHO IT'S FOR • Junior developers who want to sound — and think — more senior • PMs, designers, and founders who work with engineering teams • Bootcamp grads and self-taught devs filling knowledge gaps • Anyone prepping for technical interviews WHAT YOU'LL MASTER 8 sectors of the jargon universe: Architecture, Code Craft, Data & Storage, DevOps, Team & Process, Security, Networking, and AI/ML. Decoupling, idempotency, CAP theorem, CI/CD, zero trust, RAG, and hundreds more. HOW IT WORKS • Daily missions — one concept, 3–5 minutes, every day • Debrief quizzes — three questions to lock it in • Orbit streaks — build the habit, don't break the chain • Signal & ranks — climb from Cadet to Jargonaut • Games — personal crosswords built from terms you've charted, a weekly community crossword, and Hangman when you ace your debrief • Works fully offline — learn on the subway, sync later Go Pro to chart every sector, pin your favorite domain, run extra missions, and get the weekly crossword delivered straight to your lock screen. Reach Rank 5 and the app's name becomes your identity: you're a Jargonaut. Start your first mission today — it takes three minutes.
