All-in-One Calculator Web App with Django

Project Overview

This is a unified web-based platform built with Django that provides multiple types of calculators – Basic, Scientific, Graphing, Financial, Printing, Specialized (BMI, Unit Conversion, etc.), and Software/Online Calculators – all inside one central system. The goal is to offer a fast, responsive and user-friendly interface to perform different kinds of calculations without switching between multiple tools or apps.

Key Features

Basic Calculator: Standard arithmetic operations (+ − × ÷)
Scientific Calculator: Trigonometry, logarithms, exponentials, factorial, π, e, degrees/radians
Graphing Calculator: Plot custom mathematical functions in real-time
Financial Calculator: Mortgage, loan EMI, compound interest, investment returns
Printing Calculator: Keeps a calculation log with “print style” view
Specialized Calculators: BMI calculator, Unit conversion, Age calculator, Date difference, etc.
Responsive Glass UI: Blur glassmorphism design using Bootstrap + CSS effects
Modular Django Structure: Easy to add more calculators later with minimal code changes
