PitchCut Rafter Lab, a pocket workshop for roof math

Why it surfaced

PitchCut turns span, run, overhang, and pitch into line lengths, plumb and level cuts, diagrams, and shareable cut lists without an account or cloud project. Its careful disclaimer—that the calculations are educational geometry, not stamped engineering—makes this unusually specific tool more credible, not less.

An offline Android tool for rafter geometry, hip and valley helpers, birdsmouth checks, sheathing takeoffs, and on-device cut lists.
