About

Maturityline: Concrete is an on-device concrete workbench for time-temperature factor, equivalent-age, and maturity-strength estimates across pours and curing scenarios. KEY FEATURES - Nurse-Saul maturity integration - Arrhenius equivalent-age estimate - Timestamped concrete temperature history - Datum, reference-temperature, and activation controls - Strength-target context kept separate from calculation - Editable sensor records plus CSV import - Pour scenario comparison - Local PDF analysis packet - Forty original offline concrete reference plates ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core tools and bundled reference material work offline - Work remains on device unless you deliberately import, share, or export through an Apple system interface Maturity estimates do not replace project calibration, test specimens, engineer approval, or required acceptance testing.
