Are the span values themselves behind Premium?
No. Every span value comes from published, code-recognized tables and is free to look up, on the reference pages and inside the planner. Premium adds the printable packet, the export, and the room to plan a bigger job. It never withholds a figure, a source citation, or the safety disclaimer.
Is the material takeoff free?
Yes. A free project of up to 4 members shows its full material takeoff - piece counts, lineal feet and board feet - and its whole-project pass/fail summary, on screen. Premium is what lets you print that packet, export it, and build projects past the 4-member cap.
