builDx - Construction Reporter

builDx is a construction management app for contractors,
site managers, and builders - with a construction calculator,
cost estimator, and site diary built in. Your data never
touches our servers. It lives on your device and your Drive.

CONSTRUCTION CALCULATOR & ESTIMATOR

Generate detailed cost estimates for any project. Choose
South Asia (Nepal/India) or Global (USA/Australia/Europe)
modes. Break costs down by material, labour, and phase -
then export a professional PDF to share with your client.
Economy, Standard, and Premium tiers built in.

MATERIAL & LABOUR COST TRACKER

Log every material purchase and labour expense against a
vendor. Track unit costs, quantities, and totals. Know your
real building cost at every stage - not just at the end
when it is too late.

VENDOR & BUDGET MANAGEMENT

Build your vendor list, manage advance payments, and track
outstanding balances. Full financial report per vendor -
expenses vs. paid vs. balance due.

SITE DIARY & PHOTO LOG

Record daily site updates with photos. A timestamped
construction log for milestones, delays, decisions,
and progress shots.

DRAWINGS & DOCUMENT STORE

Attach floor plans, elevations, structural drawings,
electrical layouts, and PDFs to your project.
All files, one place.

WORKS WITHOUT INTERNET

No wi-fi on site? builDx runs fully offline on your device.
Everything is stored locally. When you are connected, sync
to your own Google Drive with one tap.

YOUR DATA NEVER LEAVES YOUR HANDS

There is no builDx server. No account required to start.
Your project data syncs to your personal Google Drive -
a folder you own, control, and can access anytime,
even without the app. We never see your data.

Built for the people who actually build things.
