Material estimates
Calculate area, volume, roofing, stairs, lumber, drywall, concrete, paint, flooring and wall framing with adjustable waste and rounding.
Built for field work
Job-site estimates and reports, kept together.
FieldCalc helps contractors and handymen keep measurements, material estimates, photos and PDF reports in one project record — even when the job site has no connection.
A clear job record
Capture the work while you are on site.
Photos and notes
Capture or import job photos, add visual annotations and keep them connected to the related calculation.
PDF reports
Generate a reviewable project report from the saved inputs, results, notes and photos — offline.
Local first
Your device is the primary workspace.
FieldCalc saves confirmed project changes on your device first. Pro users may choose optional iCloud sync and single-project collaboration; a cloud issue never prevents working with the local project.
FieldCalc provides estimates, not professional certification.
Verify measurements, product specifications and local requirements before purchasing or building.
