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?
