Building My First Web App: A Feature-Packed Offline PWA Calculator

I'm thrilled to announce the launch of my inaugural web application: an installable Progressive Web App (PWA) meticulously crafted using HTML, CSS, and Vanilla JavaScript. My objective was to create a tool that is both highly accessible and adaptable, catering to a diverse range of users, including older adults, shopkeepers, students, and general users.

The calculator boasts an impressive array of features, spanning multiple modes such as Standard, Scientific, Sales, Interest (Simple & Compound), Unit Conversions, BMI, Age, and Adjustable Percentage calculations. Users can tailor the interface to their preferences, adjusting button sizes and selecting custom background themes, including Dark and Light modes.

One of the standout aspects of this project is its offline capability. Leveraging service worker caching, the application ensures seamless functionality even without an internet connection. Moreover, users can directly install the PWA on their mobile or desktop devices, making it readily accessible anytime, anywhere.

I invite you to explore the live demo at mdalif027-tech.github.io/easy-calculator. Your feedback is invaluable to me as this marks my first web project. I'm particularly interested in hearing your thoughts on the mobile touch layout and responsiveness across various screen sizes. Additionally, any suggestions for UI/UX design improvements or future features would be greatly appreciated. Thank you for taking the time to check out my work!
