Numio Calculator Máy tính ứng dụng cho Android mô tả
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.
