Hey Product Hunt I got tired of calculator sites that hide a simple tool behind pop-ups, sign-ups, and ad walls. So I built BSM Sites: free calculators for finance, health, math, and everyday life — instant, no sign-up, works worldwide. I'm adding more every week, so tell me: which calculator do you use most — and what should I build next?

Building a free calculator site, which calculator do you wish existed?

Hey everyone,

I'm launching BSM Sites tomorrow, a growing collection of free calculators for everyday life (finance, health, math, dates, and a few fun ones like dog/cat age and a World Cup league table). The whole idea came from being frustrated with calculator sites that bury a simple tool under pop-ups and sign-up walls. So everything here is free, instant, and needs no account.

Before I go live, I'd genuinely love input from this community:

Which calculators do you actually reach for most?
Is there one you've always wished existed but could never find a good version of?
