Original Summary

I wanted something really simple: enter one amount and immediately see it converted into four currencies at once. So I built FourEx. No ads, no subscription, no account — just the calculator and forex info. I finally finished it and I’m curious what other travelers/builders think. What would you change?   submitted by   /u/not-a-bourgeoisie [link]   [comments]
