Themes and customisation
A Calculator You Can Actually Make Your Own
Most calculator apps treat appearance as an afterthought. LumioCalc keeps the maths practical while giving you far more control over how the calculator looks and feels.
Built-in themes
LumioCalc includes ready-to-use themes so you can change the look without spending time designing one yourself.
Deep custom styling with Pro
- Background colours, gradients and images.
- Button shapes, shadows and corner radius.
- Separate colours for digits, operations, functions, memory and scientific buttons.
- Display and toolbar typography.
- Haptics, button sounds and animation styles.
Still a scientific calculator first
Themes do not replace the calculator features. Scientific functions, history, expression support and the everyday calculator remain available whether or not you buy Pro.
