Glucocalc-Qt — Glucose/HbA1c Calculator (Qt Desktop)

Qt 6 Widgets port of Glucocalc — estimates HbA1c and average blood glucose using the 2008 ADAG Study Group formulas, plus glucose/HbA1c unit conversions.

Runs on macOS, Windows, and Linux from a single CMake + Qt 6.11 codebase. Static Qt builds.

Features

• Keypad-driven input: 7 8 9 C / 4 5 6 ⌫ / 1 2 3 = / 0 ., with = computing, C clearing, ⌫ backspacing
• Calculate eAG (from HbA1c) and Calculate HbA1c (from eAG) modes
• UK (IFCC) switch converts current input on the fly (mg/dL ↔ mmol/L, % ↔ mmol/mol) and recomputes
• Results always show both units (mg/dL + mmol/L, % + mmol/mol)
• Help dialog with usage, terminology, formulas

Math (2008 ADAG)

• eAG = 28.7 × A1c − 46.7 (mg/dL); mmol/L = /18
• A1c = (eAG + 46.7) / 28.7 (%); IFCC = 10.93 × A1c − 23.50 (mmol/mol)
• NGSP = 0.09148 × IFCC + 2.152; mmol/L ↔ mg/dL: ×18 / ÷18

Build

Requires static Qt 6.11.1 (CMAKE_PREFIX_PATH per AGENTS.md).

# macOS
cmake -S . -B build
cmake --build build
open build/glucocalc.app

# Linux / Windows — same, with platform Qt kit
cmake -S . -B build -DCMAKE_PREFIX_PATH=/path/to/Qt.6.11.1-static
cmake --build build

See AGENTS.md for per-platform paths and packaging.
