Breaksheet is a field QC lite app for independent labs and third-party CMT testers. The loop is one job: capture an ACI cylinder set, move it through the lab, enter the ASTM C39 break, and share a client PDF with an audit trail.
It is a sister app to Entraine. Entraine is plant QC. Breaksheet is specimen, lab, and report — concrete cylinder sets only.
