What's New in GearTech OS

September 18, 2026

The camera reads now. Photograph an isometric, a problem sheet, the stencil on a pipe, or a calculation written by hand, and the app pulls out the numbers and solves it. Everything is read on your phone; photos never leave it. Cut length fixed: it now subtracts the weld root gap, the way it is done in the field. The keypad and the assistant give the same number. The assistant understands far more: elbow, tee and reducer take-offs from ASME B16.9 tables, pipe weight and capacity, inside diameter, circumference, water velocity, electrode amperage, and wall transition against B31.3 and API 1104 thresholds. Ask it the way you talk on the job. Solves what is missing on an isometric: elevation difference, a dimension chain with one blank, slope, unknown angle and rolling offset — with the math shown step by step. Arc marks for cutting elbows in the field: back, side and throat. Pipe from 22" through 48", including 34" and 42". Nine languages: Spanish, English, Portuguese, Tagalog, Vietnamese, Haitian Creole, Polish, Russian and Chinese. New settings: units, 1/16 or 1/32 fractions, millimeters, root gap, defaults and voice. Backup: save and restore your cut lists, jobs and settings.
