## What is Hyspecs Tools.?

Hyspecs Tools brings hydraulic calculators and design references together in one iPhone app for sales, service, and engineering work.
Use native calculator screens for common hydraulic requirements, including cylinder force, orifice flow, displacement, hose velocity, pressure drop, motor torque, pump power, accumulator sizing, conveyor drives, and more.
The app also keeps important reference material close at hand, including bundled PDFs and spreadsheets that have not been converted into native calculators. Search by tool, topic, product, or file name, save frequently used references, and open document previews without digging through a folder.
Built for practical field and customer conversations, Hyspecs Tools helps engineers move quickly from a question to a useful estimate.
Calculator results are intended as engineering aids and should be checked against manufacturer data, project requirements, and appropriate safety factors.
