Decades of grading logic — one clean app.

Velura translated GrainPro's complex raw-grain grading rules into a clean, user-friendly mobile + data-calc app. On time. Strong technical judgement throughout.

Domain-heavy apps die in two ways: oversimplifying the rules, or shipping a UX that demands a manual. GrainPro's grading rules — decades of agronomic decisions — needed both depth and ease. We built the engine, then the experience.

What they asked for.

Rules engine first

Captured the grading logic as a versioned rules engine — testable, auditable, with explainable outputs for every grade.

UX without the manual

Progressive disclosure — beginners see the simple flow, experienced users see the levers. Empty / loading / error states designed in.

Data-calc surfaces

Calculation views for moisture, foreign matter, damaged kernels, with audit-friendly explanations of every figure.

Crisp written communication

Decisions captured in shared docs; questions asked once, in writing, before implementation. No churn.
