"As a custom furniture builder, I am constantly switching between metric blueprints and my imperial shop tools. This app is a lifesaver—the fraction rounding feature matches my tape measure perfectly and saves me from costly mistakes. The history log is also a great bonus for tracking dimensions across a whole project."
