The problem · 01

You read it fine.
You blank live.

Reference apps and charts help you look a code up. They do not train recall. So the meaning is there when you read it, and gone the second someone asks you in class or at the machine.

The problem · 02

Manuals are built
to reference.

A machine manual is the right tool for looking things up and the wrong tool for memorizing. You do not need another few hundred pages. You need quick, repeated reps.

The problem · 03

Generic flashcards
are not CNC.

Plain decks make you build the cards before you learn a thing, and they skip the mix-ups that actually trip beginners up. G-Code Sprint comes prebuilt for CNC, mix-ups included.

How it works

Pick a pack. Practice.
Review what you missed.

Three short steps. No manual reading, no deck building. Just the codes you need to know, drilled until they are automatic.

Step 01
Pick a drill pack

Beginner G-codes, M-codes, Haas/Fanuc-style basics, modal codes, or common mistakes. Start where your class is.

Step 02
Practice fast recall

Answer code-to-meaning, meaning-to-code, and common mix-up questions. Short reps, a few seconds each.

Step 03
Review weak codes

The app repeats the codes you miss until they stick. Your weak list shrinks every session.

Drill modes

Six ways to drill the basics.

both directions.
G00 shows, you recall Rapid positioning. Then flip it: clockwise arc shows, you recall G02. Recognition first, then recall in reverse.

Mode
Meaning → Code
Counterclockwise circular interpolation, you answer G03. Recall in reverse.
Mode 06
Weak-code review repeats what you keep missing.
Every wrong answer lands on your weak list. The app brings those codes back until they stick, so your blind spots shrink each session, not your patience.

Why not flashcards

Look it up,
or lock it
in.

Reference apps and manuals help you look a code up. Generic flashcards make you build the deck before you learn anything. G-Code Sprint is built for CNC recall instead: prebuilt beginner drills, timed pressure, the common mix-ups, and weak-code repetition. A clean apprentice-friendly interface, no setup, no busywork.

A note from the founder
“ I kept seeing beginners who could read G-code fine freeze the moment someone asked them out loud. G-Code Sprint is the drill I wished they had: five focused minutes, the codes people actually mix up, repeated until they stick. ”

Honest questions.

No. G-Code Sprint is a practice and memorization tool, not a CNC simulator or machine controller. It trains recall of common G-code and M-code, nothing more.
CNC beginners, trade school students, and machinist apprentices who want to memorize common G-code and M-code faster, plus beginner operators learning Haas/Fanuc-style basics.
No. The first version focuses on the most common beginner codes and the common mix-ups. It is built to be useful fast, not exhaustive.
No. G-Code Sprint is a study and practice tool only. Always follow your instructor, employer, machine manual, and shop safety procedures.
The early version focuses on common beginner concepts that carry across controllers. Future packs may add controller-specific practice modes.
The plan is a free preview plus a simple one-time lifetime unlock. No subscription, no card to try it.
