Save selected estimates locally on your device and reopen them later. Export supported calculation results as PDF summaries through Android's standard sharing options.

OFFLINE-FIRST AND PRIVACY-AWARE

Core calculation inputs and saved estimates stay on your device, subject to Android backup settings. No CiviBuild account is required. The free app is supported by banner and optional rewarded advertisements, with privacy choices available where required.

IMPORTANT

CiviBuild provides planning estimates only. It does not replace approved drawings, local building codes, supplier specifications, site measurements or review by a qualified engineer. Always verify quantities before purchasing materials or beginning construction.
