Scientific Calculator App - Powerful, Lightweight, and Secure

Project Overview:

The Scientific Calculator app, developed by Pabitra Banerjee, is an advanced yet lightweight and open-source calculator designed for versatility and privacy. This app supports a wide range of basic and advanced mathematical functions, making it a valuable tool for both everyday calculations and scientific computations. It prioritizes a user-friendly experience through a well-designed interface, intuitive controls, and error handling for accurate and efficient calculations.

Our Approach

We focused on creating an efficient, secure app with no need for backend data collection, enhancing both privacy and performance. Through Flutter’s customizable components, we developed an intuitive UI with both Light and Dark modes, adaptive input font size, and easy navigation. Each function was carefully designed for a smooth user experience.

The Solutions

Using Flutter enabled seamless compatibility across Android devices. The app incorporates features like scrollable input fields, smart cursor management, and a comprehensive history log for calculations. With advanced trigonometric, logarithmic, and exponential functions integrated, we ensured the app’s utility for scientific, academic, and professional use.

Project Features:

  • Basic Arithmetic Operations
  • Advanced Functions (Trigonometry, Logs, Exponentials)
  • Responsive Design with Dark/Light Modes
  • History Log for Past Calculations
  • Angle Unit Toggle (Radians & Degrees)
  • Approximate Result Handling
  • Function Buttons (√, 1/x, eˣ)
  • Persistent Data Storage for Settings
  • Customizable Display & Font Sizing
  • Error Handling for Valid Expressions
  • Intelligent Bracket and Operator Management

Challenges:

A key challenge was ensuring accurate handling of complex calculations and error-free input management. We tackled this by implementing a reliable algorithm for equation parsing and enhancing Flutter’s input handling capabilities. Additionally, balancing advanced functionality with a lightweight design.

Outcome:

The Scientific Calculator app was successfully launched, receiving positive feedback for its intuitive interface, wide range of functionalities, and privacy-centric design. The app is now a go-to tool for users requiring a versatile calculator that performs both basic and scientific calculations efficiently.
