What is Grease Sheet?

Grease Sheet is an offline-first, high-contrast digital field guide built for tradespeople who work in shops, on job sites, and out in the field. It puts instant access to industry reference charts, unit conversions, and illustrated technical how-to guides right in your pocket — no internet connection required. Whether you need a wire gauge ampacity chart, a tap drill size, a MIG voltage setting, or a quick refresher on reading a caliper, the answer is a couple of taps away.

The app is designed for welders, fabricators, machinists, electricians, mechanics, and maintenance technicians — anyone who needs fast, reliable reference material in a rough environment. Every chart and guide is laid out for high contrast and large tap targets so it stays readable under harsh shop lighting, with gloves on, or from across a bench. A built-in print and export view turns any reference page into a clean, clutter-free hard copy you can pin above the workbench.

Grease Sheet is built and maintained by an independent team of makers and trade professionals who use these references every day. The data is compiled from long-standing industry standards and shop experience, then distilled into simple, no-nonsense tables and diagrams. We keep it lean, fast, and always available — the kind of tool we wished we had on the floor.
