Edit NC/G-code, review 3D toolpaths, inspect stock removal and view STEP/STL models on iPhone and iPad. iNC-Mill brings programs, toolpaths and part geometry into one workspace for shop-floor review, programming practice and teaching. File management and basic 3D viewing are free. NC editing, simulation, knowledge references, calculators, advanced 3D tools and settings, and AI questions require an active subscription. NC/G-CODE EDITING • Import NC programs from Files, AirDrop or other apps • Edit with syntax highlighting, line navigation, search and replace • Renumber or remove N block numbers in selected lines or an entire file • Review very large programs in a dedicated read-only mode MILLING, TURNING AND MACROS • Watch stock removal during 3-axis milling and turning playback • Set up box, cylinder or tube stock for milling, and bar, tube or stepped stock for turning • Save reusable stock presets, set dimensions and workpiece origins, and keep confirmed settings with each program • Inspect 3-axis and 5-axis toolpaths with distinct rapid, feed and arc motion • Trace FANUC macro execution flow and machine state • Work with Mitsubishi M800/M80 milling and turning programs, with matching command references, parameter forms and examples • Review supported Haas NGC 3-axis milling and 2-axis turning commands, common cycles and dedicated settings, with matching references and examples • Review macros, subprograms and canned cycles within the supported scope of the selected controller CODE BESIDE TOOLPATHS • Compare 3D toolpaths with read-only NC code in resizable Machining-mode panes • Follow associated source lines and available tool, feed, spindle and position readouts • Navigate by move, Z change, cutting section or tool section • Play forward or in reverse; adjust speed, path colors and viewing direction • Keep the camera and playback position when switching preview modes STEP/STL MODEL VIEWING • Open STP/STEP and STL files; rotate, zoom and use standard views • Explore STEP assembly trees, hide or isolate components, and adjust exploded views • Inspect internal geometry with interactive section planes • Measure supported STEP geometry: distances, radii, angles, areas and model dimensions • Measure between toolpath points and visible simulated workpiece surfaces Model viewing is read-only. STEP measurements use supported CAD geometry; STL and simulated workpiece measurements are mesh-based approximations. Toolpath curves use generated segments. Measurements do not certify physical part dimensions. FILES AND MACHINING TOOLS • Create, import, search and organize files; reopen recent files • Move files and folders in batches, copy folders and restore Recently Deleted items • Review program tool checklists to verify executed tools, spindle speeds and feedrates • Manage machine and tool definitions; browse 8 milling and turning controller libraries and insert generated G/M-code commands using parameter forms • Use milling, turning and quick calculators ON-DEVICE WORKFLOW Core NC editing, parsing, model viewing, toolpath review and simulation run on device. These tools do not require uploading your machining files. iNC-Mill supports program review and visualization. Professional verification, collision checks and machine, tooling and fixture checks remain necessary before machining. SUBSCRIPTIONS Monthly and yearly plans, prices and any available trial are shown in the App Store at purchase time. Payment is charged to your Apple ID after confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel in Settings > Apple ID > Subscriptions.

Verdict
The clearest difference is price: iNC at Free against 程轨's $2.99. iNC also leads on update cadence (every 5 days vs monthly). 程轨's advantage is in-app purchases (none vs 2) and iOS requirement (13.0 vs 16.0). On ads and device support there is nothing between them.
