VimKata vs Terminal Drill

VimKata is a companion app for learning Vim. It teaches you the concepts — what commands exist, how they compose, when to use them. Your physical keyboard builds the muscle memory. Learn in the app, apply in your editor. Every command is demonstrated before you practice it. The buffer animates step by step, a keyboard replica highlights the key being pressed, and a register indicator shows what was stored. You see what a command does before you're expected to use it. A COMPANION, NOT A REPLACEMENT VimKata teaches the mental model. The phone teaches the grammar; the terminal teaches the typing. Pick it up for 10 minutes on a commute, a break, or before bed — then apply what you learned on a real keyboard. DEMO → KATA CYCLE Each exercise starts with an animated demo. A keystroke timeline tracks each step. A MacBook keyboard replica highlights the key. Then you practice on the on-screen keyboard. You never guess — you see it first, then try it. PRACTICE ON REAL CODE Exercises use real JavaScript, Python, HTML, CSS, and Markdown — not toy examples. Each exercise has a concrete editing goal: transform this code into that code. One concept per exercise. SCORE EVERY KEYSTROKE Every exercise produces a grade from S (perfect) to D (keep practicing). After completion, the app shows the optimal solution alongside yours so you can see exactly which command would have been shorter. Retry to improve your grade. 7 LEVELS, 135 EXERCISES - L1: Basic Motions — h j k l w b e 0 $ gg G f t - L2: Basic Editing — x dd dw yy p P cw o - L3: Operators + Motions — de ct df dt ye cc 3w - L4: Text Objects — diw daw ciw ci" da" ci( di( ci{ - L5: Visual Mode — v V d y c ~ o - L6: Navigation Mastery — W B E F T ; , % - L7: Quick Edits — r s J O I D C ^ ~ Levels 1–3 are free.

Each level has introductory exercises (guided, one command at a time), practice exercises (realistic code, full demo), and challenge exercises (no demo, no hint, tests combined skills). VIM IS A LANGUAGE Most people learn Vim as a list of commands. VimKata teaches you the system underneath — operators compose with motions. Delete a word. Change to end of line. Yank through a character. Once this clicks, you stop memorizing and start composing. BUILD YOUR PRACTICE QUEUE Bookmark exercises for commands you're actively learning. The Saved tab on the home screen gives you quick access to your personal practice list.

Build command-line confidence, one useful session at a time. Terminal Drill is an offline practice companion for terminal skills, developer workflows and Linux administration. Learn with short lessons, recall commands, troubleshoot simulated machines and take the same tasks to your own system. FOUR LEARNING TRACKS • Terminal Foundations — files, text, permissions and everyday shell skills. • Developer Workflows — Git, shell productivity and automation. • Linux Operations — services, networking, storage and containers. • RHCSA preparation — a RHEL 10 curriculum with 83 lessons, review assignments, 48 chapter labs and six capstones. PRACTISE, THEN APPLY Choose guided practice or independent recall. Use hints when you need them, then return for a later retrieval attempt. Practical labs check the represented machine state, including protected data and configuration that must survive a simulated reboot. Each lab declares its supported commands and limitations. Companion guides help you practise on a disposable real system. The 66 practical labs include twelve additional exercises across shell reasoning, Git recovery, files and text, service troubleshooting, networking and container operations. Labs are bounded teaching simulations, not a Linux runtime. They remain labelled as awaiting independent technical review; completion is not a certification or an exam-readiness guarantee. CLASSIC OR ADVENTURE Keep the familiar Classic experience, or switch to Adventure in Settings. Adventure adds missions, a character profile, twelve achievements, earned titles and cosmetics, flexible weekly goals and a collectible homelab. Progress, XP and purchases are shared between modes. Switch whenever you like.
