Use the free tools first, then buy the working files.
The calculators stay free. The paid layer is for reusable spreadsheets, printable binders, roof planners, cheat sheets, and build packs you can actually keep using in the garage or at camp.
This turns the free worksheet into a reusable planning file you can update in the garage, on the road, or during an upgrade round.
