You've seen the terminal. Your AI assistant practically lives in it. Time to actually read what it's typing. Terms teaches you real terminal commands the way a vocabulary app teaches words — one card at a time, a few a day, until they stick. THE WIDGET IS THE APP Add the home-screen widget and a new command appears next to your apps every day. Read it when you unlock your phone. No app open required. A FEED YOU CAN BINGE Full-screen flashcards drawn as terminal windows: the command, what it does, every flag explained piece by piece, and why you've seen it before — "agents use grep to locate where code lives." HONEST LEVELS A 60-second placement test deals you in at the right tier: on-ramp, daily driver, combos & power, or deep cuts. No fake progress, no flattery — the deck starts exactly where your knowledge ends. PRACTICE THAT STICKS Quick quizzes built from the cards you're learning, with spaced repetition scheduling the reviews. Tap "just got it!" or "alr knew it" — that's the whole ceremony. CALM BY DESIGN • One notification a day. Opt-in, at your time, hard cap two. • Free, offline, no account, no ads. • Dangerous commands carry the warning they deserve (looking at you, rm -rf). WHAT'S INSIDE 231 real commands and concepts at launch — ls, cd, grep, cat, lsof -i :3000, chmod, pipes, redirects, xargs, sed, awk, tar — tiered from total beginner to power user, searchable in the library, every one tracked to mastery. Built for everyone shell-adjacent: vibe coders shipping with AI, students, new developers, and anyone who has ever copy-pasted a command and prayed. The terminal is the first course. More languages of code are coming.
