Last few months, I was frustrated. Every time I needed to calculate EMI or check my BMI, I had to visit a site full of pop-up ads and trackers. Many tools were also very slow on mobile data in Pakistan.

So I started building a collection of small, single-purpose tools.

What I Learned While Building 50+ Tools

Privacy First - Most tools send user data to a server. I decided to make everything work in the browser itself using pure JavaScript. No data leaves the user's device.

Performance Matters - I used simple HTML, CSS, and vanilla JS. No heavy frameworks. Tools load in under 1 second even on 3G.

My Simple Tech Stack - HTML5 + Tailwind CSS + JavaScript. All calculations are done client-side.

My 5 Most Used Tools

• EMI Calculator for loan planning
• BMI Calculator for health check
• QR Code Generator for business
• SIP Calculator for investment
• Age Calculator and Word Counter

My Promise

My goal is simple: Open, Use, Done. No ads spam, no tracking.

I have put the live version on my personal domain. Happy to share code snippets if anyone needs help.
