Open the G-code file you actually have — and see it.
OPENS MODERN SLICER OUTPUT
PrusaSlicer, OrcaSlicer, Bambu Studio, Cura, SuperSlicer, Klipper, Marlin. GCodeView recognises G-code by its contents, not its file name, so files named .txt or shared without an extension open too. If a file is a ZIP, PDF or image instead, the app says so.
HANDLES LARGE FILES
The parser streams the file from disk instead of loading it into memory — a 37 MB file loads in under a second on a recent phone. While you rotate or zoom a big model, the toolpath is drawn at lower detail and sharpens when you stop.
SEE THE PRINT, LAYER BY LAYER
The toolpath renders in 3D with rotate and zoom. Scrub the layer slider to watch the print grow, inspect a single layer, or show travel moves in dim. Read what the file says: estimated time, filament used, layer height, temperatures, dimensions.
FREE, NO ADS, FULLY OFFLINE
No account, no subscription, no ads. Your files never leave your device.
FEATURE COLORS
Color the toolpath by slicer feature type — perimeter, infill, support, bridge — with a legend.

A fresh look and clearer file info.
GCodeView has a new black stage with a nozzle-shaped layer slider and a height readout while you drag. The file info sheet is redesigned, and Cura time estimates now show as 5m 17s instead of raw seconds. Feature colours are translated, the model no longer hides behind the slider, and reopening from recent apps no longer reloads the last file.
