Edit: Spoke too soon. Equate does seem to offer a complete list of currencies. Will take a look at this.
A far as I can tell the only currency converter for [fiat] currency is billthefarmer’s aptly titled Currency. Definitely need this. XE Currency has been a great tool for me, but would like to see something that can go on F-Droid.
Has this topic come up before (didn’t find it in forum search)? Is anyone working on something like this. I am open to forking Currency, or starting something new, but would like to know more about what may have come of this idea up till now.
