CalcLab is an all-in-one application which includes a scientific calculator with graph plotting capability, date comparator, currency converter (real-time rates), and 12 more converter tools. It is designed to be as easy to use and as straightforward as possible. It also has a beautiful flat-modern GUI which makes it fit seamlessly into any workspace.
Generally, when people want to perform conversions or calculations, they must look up on the internet to get the right tools. However, that is inefficient and not so productive as they have to waste their precious time finding the right tools, not to mention some people even have a hard time finding the right tools. This is where CalcLab will solve the problem as it has all the right tools located at their fingertip, and it is very easy to use.

Supports: add, subtract, multiply, divide, percentage, square, cube, square root, cube root, factorial, natural logarithm, common logarithm (base 10), sin, cos, tan, sinh, cosh, tanh, e constant, pi constant
Other features:
- Auto detect invalid input (i.e. contains non-numeric character) and invalid number operations (i.e. dividing by 0)
- Auto prevent user from using more than one decimal point
- If the result is the same as what is currently displayed (i.e. 4/2 = 2), the display will blink, indicating that the result is updated
- Auto conversion to scientific notation when the result is too long
- Able to do continuous calculations, no need to press AC (i.e. pressing 5 + 2 x 2 will give out 14)
- Result will be automatically stored in history
Supports:
- Straight line
y=mx+c,x=my - Parabola
y=mx^2+c - Cubic graph
y=mx^3+c - Graph of
npowery=mx^n+c; 0 ≤ n ≤ 6
User can also type /undo to remove the latest plotted line.
Examples of supported equation:
y=20
x=5.23
y=2x
y=-2x+10
y=(1/2)x^2-(100/3)
f(x)=-0.03x^2.5+20
y=(1/3)**3x^2+(25/2)**1.3
Everytime user calculates something, it will be stored in a text file history.txt which user can view it right from the program. User also has an option to clear all history.
When user presses the upper left button, the selection menu will appear. From here, they can select tools they want.
Supports: Calculate date difference and output in year, month, week, day, and sum of day.
Other features:
- Auto detect invalid input (i.e. contains non-numeric character, invalid date number, not entering date completely)
- If the year/month/week/day is 0, it will not be displayed
- Suffix (s) is automatically determined
