Air content and AEA dose help for ready-mix QC, even with no signal at the plant.

Entraine is an iPhone app for ready-mix concrete quality control. You log a load's fresh-concrete tests (air content, slump, concrete and air temperature), and Entraine suggests the air-entraining admixture (AEA) dose for the next load. If a load misses air, the Fix Load screen gives a correction in ounces.

It's built for QC techs, batch operators, and plant managers at ready-mix plants. It works offline first, so you can log tests in the yard and sync later. Each company enters its own plants, mixes, and admixtures. Nothing is preloaded from any producer.

You can scan a delivery ticket or batch weights with the camera to fill in the load details, and the app learns your ticket layout after one scan. Temperature checks follow state DOT and ASTM limits, and manufacturer safety data sheets (SDS) are saved on the phone for offline viewing.

Beta on TestFlight, not on the App Store. Planned price: $9.99/month with 2 plants included, +$2.99/month per extra plant, or $79.99/year, with a 15-day free trial.

Features

• Log QC, then Suggest, then Fix Load: a next-load AEA dose from your plant's own history, and an ounce correction for a load that's off.
• Ticket and batch-weight scanning that learns your layout and checks batch weights against the mix design before anything applies.
• Hot and cold weather checks from state DOT and ASTM C94 limits, with ice and chilled-water suggestions.
• Offline-first, with company sharing through iCloud, including a shared Docs library.
• Admixture SDS and product sheets from the major admix manufacturers, viewable offline.
• A one-tap demo plant to try the app without setting anything up.
