Glucocalc — Glucose/HbA1c Calculator (Android)

A Kotlin calculator that estimates HbA1c and average blood glucose using the 2008 ADAG Study Group formulas, plus glucose/HbA1c unit conversions. Behavior and look match the SwiftUI iOS/macOS version.

Features

• Keypad-driven input: 7 8 9 C / 4 5 6 ⌫ / 1 2 3 = / 0 ., with = computing, C clearing (zeros input + results), ⌫ backspacing
• Calculate eAG (from HbA1c) and Calculate HbA1c (from eAG) modes
• UK (IFCC) switch converts the current input to the other unit system on the fly (mg/dl ↔ mmol/L, % ↔ mmol/mol) and recomputes results
• Results always show both units (mg/dl + mmol/L, or % + mmol/mol)
• Display: three label/value rows, all values 0 initially and after C
• Day/night adaptive theme, rounded-square keys, Help dialog in the toolbar

Math (2008 ADAG Study Group)

• 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
