Why I built CalculBox

Hey Product Hunt! 👋

I built CalculBox because I was tired of landing on slow, cluttered calculator websites full of ads and pop-ups just to calculate a simple tip or check my BMI.

So I made something better — fast, clean, and actually pleasant to use.

What's inside: 🎂 Age Calculator — your exact age in days and hours ⚖️ Smart BMI — adjusts by age and gender 🌍 Tip Calculator — tipping rules for 10+ countries 🎨 HEX to RGB — with Pantone Colors of the Year 📅 Days Between Dates — exclude weekends too % Percentage Calculator 🎲 Random Name Picker 🔤 Case Converter 📝 Text Counter

No sign-up. No downloads. Completely free. Forever.
