## What is Construction Toolkit?

Construction Calculator is an offline construction calculator for people who build things: concrete calculator, rebar calculator, brick, tile, steel, scaffold and pipe volume - with a material estimator and cost estimator that work with no signal.

No account. No signal. The app works anywhere - a job site, a basement, a rooftop - and it never sells your data because it never needs the network.

WHAT YOU CAN DO
- Concrete calculator: slabs, footings, columns and walls - bags, volume, cost.
- Rebar calculator: footings, beams and ties - steel weight and volume in one tap.
- Brick, tile, beam, column, roofing, scaffold, excavation, asphalt and pipe volume calculators.
- Unit converter: metric and imperial, plus construction units. Use this unit converter offline on the job.
- The material estimator and cost estimator build as you work.
- Save projects and reopen them anytime.
- Export a clean, print-ready PDF or structured Excel file.

MADE FOR THE FIELD
- This construction calculator works offline on site - even with no signal.
- Big numbers and large buttons, readable in daylight and on the move.
- Smart defaults and quick presets to cut your typing.
- Dark mode for evening planning.
- Every result can be copied or shared in one tap.

FREE, WITH A PRO OPTION
- All calculators are fully free. No paywall in the middle of a calculation.
- Pro removes the limits on saved projects, unlocks branded PDF export and full-project Excel export, and restores your purchases on any device.
- No ads in pro version.
