Numio Calculator
A clean, open-source calculator with live results and unit conversion
新版本 1.0.7
- Fixed a crash when switching converter categories (for example Volume to Temperature)
- Converter shows "Number too large" or "Not a number" instead of crashing or staying blank, and accepts a comma as the decimal point (1,5)
- Converter result stays visible above the keyboard
- Landscape: the result is no longer hidden and key labels fit their buttons
- Custom colour: codes like GGGGGG now show an error
- Results like 0.1 + 0.2 now show 0.3

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.

* 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
