## What is One?

L-Calc is a smart landscape-mode calculator that redefines ease of use with one-handed operation and precision cursor control.
Unlike standard calculators, you can slide your finger to move the cursor and edit any part of your formula instantly.

Key Features:
- Precision Cursor Slide: Simply swipe the "↔" button to move the cursor through your formula. Correct mistakes in the middle of long equations without deleting everything.
- Reversible Layout: Toggle the keypad between the left and right sides to perfectly match your grip in landscape mode.
- Effortless One-Handed Use: Every button is positioned for thumb access, making multitasking smoother than ever.
- Interactive History: View previous calculations on the side and tap to insert results directly into your current formula.
- Complex Math Support: A robust engine that handles parentheses and nested expressions accurately.
