iNC vs CNCCalc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
iNC
This app provides a portable CNC workstation for editing, simulating, and calculating machining parameters. It allows for on-site tuning, travel support, and confidential machining without cloud dependency. Features include process calculators, an NC program editor, and a 3D toolpath viewer.
- Smart NC/G-code editing
- CNC simulation
- Process calculators
- 3D toolpath viewer
- Local-first file processing
- Large program handling

iNC-Mill brings NC/G-code editing, 3D toolpath review, and cutting simulation to iPhone and iPad. Preview material removal for 3-axis milling and turning, inspect FANUC macros, and work with machining files locally. Cutting simulation requires an active subscription. CLOSER, CLEARER 3D TOOLPATH REVIEW • Pick two points on a toolpath to inspect 3D distance, coordinate differences, and path length, with endpoint snapping • Select a precise path position to seek playback, or navigate by move, Z change, cutting section, or tool section • Switch to a tool view and independently lock the viewing direction • Adjust X/Y/Z display scales independently to reveal small variations • Play toolpaths forward or in reverse, with speed controlled independently of play/pause • See the associated code line when available, alongside feed F and spindle S values • Customize path colors, inspect motion counts and travel-distance shares in the legend, and filter paths by playback range Measurements describe toolpath geometry. Curves use the published path segments; these are not measurements of the physical workpiece. BUILT FOR THE SHOP FLOOR • Preview stock material removal during 3-axis milling playback • Open NC files from Files, AirDrop, or other apps • Edit with line navigation, search, and replace • Review very large programs in a focused read-only mode • Inspect 3-axis and 5-axis toolpaths with rapid, feed, and arc motion clearly distinguished • Visualize lathe stock changing as material is removed during turning playback • Trace FANUC macro execution flow and machine state • Organize machine and tool definitions • Calculate feeds, speeds, scallop height, and surface-finish references • Browse practical G/M-code reference content LOCAL-FIRST WORKFLOW Core editing, parsing, preview, simulation, library, and calculator workflows run on device. Your NC files do not need to be uploaded for these tools. USE IT FOR • Shop-floor program checks before machining • On-site edits and troubleshooting • Training and toolpath review • Keeping machining references close at hand iNC-Mill supports human review and visualization. It does not replace professional verification, collision checking, or your machine, tooling, fixture, and workplace safety procedures. SUBSCRIPTIONS Monthly and yearly options, and any available trial, are shown in the App Store at purchase time. Payment is charged to your Apple ID after confirmation.

Verdict
The clearest difference is price: iNC at Free against CNCCalc's $2.99. iNC also leads on update cadence (weekly vs every 2 months). CNCCalc's advantage is in-app purchases (none vs 2). On ads, device support and iOS requirement there is nothing between them.
