Calculator M3

Every calculation you make is your business — not Big Tech's. Calculator M3 is a beautifully designed calculator built with Material 3 that works entirely offline for everyday math, with zero data collection, zero analytics, and zero tracking.

Unlike other calculators, this app doesn't phone home. No usage tracking, no telemetry, no ad frameworks buried in the code. It does math — and an optional, fully on-device AI math solver — and nothing else.

✓ Full expression evaluation

✓ Live result preview

✓ Scientific functions

✓ Calculation history

✓ Material 3 dynamic theming

✓ Works offline (with an optional on-device AI math solver)
