ConstructionCalcs: Builder Pro

Feet-inch-fraction math, a unit converter and concrete slab yardage, all on the device with no signal. Pro unlocks the estimating answers and keeps your jobs saved.

Feet, inches and sixteenths. Added, subtracted, multiplied and divided, and read back the way your tape reads.

If you have ever turned 3/8" into a decimal, added a column of them, turned it back and cut it wrong, this is the app that stops that.

WHAT IT DOES TODAY The feet-inch calculator takes 12' 7 3/8" as an input, not as a problem. Add, subtract, multiply or divide by a scalar and get a mixed fraction, rounded to the sixteenth or the eighth, whichever your tape shows.

The unit converter moves between feet and inches, decimal feet, plain inches, millimeters and meters. Plans in metric, tape in imperial, one tap between them.

The concrete slab calculator gives cubic yards from real feet-inch dimensions, with a waste factor you can see and change, so the ready-mix order is right the first time.
