Numio Calculator 应用
Numio is a clean, minimal calculator built with Kotlin and Jetpack Compose. No ads, no tracking, no internet permission — it never needs to talk to the outside world.Features:
* Clean, minimal design with retro circular keys
* Live results — see the answer as you type
* Scrollable expression display, so long numbers are never truncated
* Calculation history saved locally with a Room database
* Built-in unit converter — Length, Weight, Area, Volume, Temperature, Time, Speed, Pressure
* Theme customization — 12 preset accent colors plus custom hex input
* Your chosen theme color is remembered across sessions
* Hand-drawn custom app icon
* A small hidden easter egg
* 100% offline — nothing ever leaves your device
This is a first solo project, built from scratch and open-sourced so anyone can use, inspect, or contribute to it.
