IOS Developer Daniel Schroeder, Bielefeld, Germany, launched a new iPhone app in May 2026. The Paving Yield Log is designed to keep track of each truckload as it is placed on the mat and report a running yield percentage per load and across the shift. The app is intended to notice yield drift early. If a load is running thick at load three, the foreman sees it at load three rather than at the end of the shift.
For every truckload, Paving Yield Log records tonnage, stationing, mat width, lift thickness, and mat temperature. The app uses a spread rate of 110 pounds per square inch as the default density baseline, and lets the user override it with the lab-measured value from the mix design report. The app can generate a per-shift PDF modeled after the Wisconsin DOT yield check sheet and a CSV export for quality control.
It runs completely offline with no account and supports US-customary and metric units. Paving Yield Log is a one-time purchase for iPhone, available in the Apple App Store.
