Built for the workshop

Useful numbers,
clearly qualified.

01

Your measurements stay yours

Calculations run on this device. We do not send your room measurements or project costs to a server.

02

Assumptions stay visible

Each worksheet explains what it models, what it leaves out, and what needs an on-site check.

03

Made for double-checking

Results show their components so you can compare them with cartons, quotes, plans, and field measurements.
