CalcHub is a free collection of 57 fast, ad free calculators covering finance, health, math, and everyday tools BMI, compound interest, GPA, & more. As a student developer, I built every calculator and page myself to fix what bugs me about existing sites: bloated ads, pop ups, and slow load times. CalcHub requires no sign-up just instant, accurate results. I’d love your feedback! Which calculators are most useful to you, and what should I build next?
Hey everyone — I'm Emmanuel Adu-Wadier, 16, and I built CalcHub solo over the past few months. I'm a student developer and I wanted to build something genuinely useful without the ad clutter and outdated design that most calculator sites have. I Would really appreciate any feedback, especially on which calculators you use most or what's missing. Happy to answer any questions about how I built it too!
