# FreshTest DC FreshTest DC Slump Air is an Android app by Anvilfield for ACI Grade-1 concrete field techs who log slump, air, temperature, unit weight, C138 yield, and per-truck PASS or FAIL records at the chute. The app works offline. It has no account, no ads, no telemetry, no analytics SDK, no remote config, and no backend upload. PDF, CSV, and ZIP exports are generated on device and shared only when the user chooses an Android share target. FreshTest DC uses user-entered project spec values and deterministic formulas. It references ASTM C143, C1064, C231, C173, C138, C172, C94, and ACI Grade 1 field-testing scope without reprinting copyrighted tables. FreshTest DC has a free mode with one active pour. FreshTest Pro is $19.99 per month, $199 per year, or $499 lifetime. FreshTest DC does not decide concrete acceptance. The testing lab, cylinder breaks, engineer of record, and contract documents remain the acceptance gate.
