This app is the working contractor's pocket reference — twelve construction calculators, a searchable glossary, and full mock exams in one app. Whether you're sizing a rebar order at the supply yard or grinding through your last week of license prep, the toolbox is built around the math and lookups you actually do every day.

WHAT'S INSIDE

12 jobsite calculators
- Concrete volume — slabs, footings, columns, with a waste factor
- Rebar weight & length — by ASTM bar size
- Lumber board-feet — from nominal dimensions
- Roof pitch & rafter — span, slope, ridge height, rafter length
- Stair layout — riser/tread/stringer with IRC code check
- Drywall & paint — sheets and gallons by coverage
- Excavation — bank vs loose volume and truck loads
- Markup ↔ margin converter
- Bid pricing — direct cost + GCs + overhead + profit stack
- Earned value — CPI, SPI, and EAC from PV / EV / AC
- Labor hours — quantity × productivity factor

Plan & Practice
- Personalized exam-day countdown
- Daily drill that builds a study streak
- Practice by domain across 15 knowledge areas
- Filter by section (Business & Law / Trade), scope (Residential / Commercial), or experience tier (Fundamentals / Advanced)
- Per-domain accuracy analytics highlight your weakest areas

Searchable Glossary
A hand-curated reference of 75+ construction and contracting terms. Plain-language definitions, source references (NASCLA, IBC, OSHA, NEC, ACI, AISC, NFPA, AIA), and an alphabet rail for instant jump.

Flashcard Mode
A separate UX from the quiz runner — tap to flip, self-grade Got it / Need work. Useful for high-frequency facts you need to recall in the testing center.

Mock Exam Simulator
Full-length timed simulations matching the two scored sections most state boards and the NASCLA Accredited Commercial General Building exam administer:
- Business & Law: 50 questions, 2 h 45 m, ≥ 70% to pass
- Trade / Building: 115 questions, 5 h 30 m, ≥ 72% to pass
Bookmark items, jump freely with the navigator, and review a per-domain breakdown after submit.

- Candidates preparing for the NASCLA Accredited Commercial General Building exam
- State GC license applicants (most boards mirror NASCLA + local amendments)
