Stair Geometry Desk
Questions about riser bands, stringer marks, seeded drills, or PDF exports? Write us—we reply from the same offline-first team that ships the workbench.
Projects stay on your device
Stair Geometry Desk uses local SwiftData only. Reinstalling the app removes local projects—export a stair sheet PDF before wiping if you need a paper trail for class or shop.
Educational, not certification
Outputs include a fixed non-certification disclaimer. Always verify rise, run, headroom, and code requirements with your local authority before cutting lumber.
