Large Font Calculator

This app started from a small, personal reason.
As my father grew older, he found it difficult to read small text, so I wanted to create a calculator with larger, easier-to-read numbers for him.

Instead of complex features, this app focuses on large text and a simple interface that anyone can use and understand at a glance.

I hope it can help others who experience similar small inconveniences like my family.
