Features

Themes
- System Theme(default)

- Light mode
Calculator
- Support for all basic operators.
- Progressive calculations.(results appear on top and change side by side as you change the expression)
- Provides commonly used constants.(Some constants might result to 0 if precision setting is not high)
- Switch between different angle measurements with ease.
- Scientific Mode that provides various trigonometric, hyperbolic and inverse functions, calculus and iterated operators, much more.
- Provides variable support.(only 1 variable)
- Precision settings for precise calculations.
- Operations like copy, cut, paste, delete are handled and results are changed accordingly.
- Vibrations when clicking buttons?(don't know if I should have mentioned it here)
DO NOTE: Inorder to use scientific features, the device should be in landscape mode.
