BUILT FOR FIELD WORK
Enter practical dimensions and get clear results immediately. Core calculators work without an account and remain available when a job site has limited connectivity.
SAVE AND SHARE
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.
