When I was an Android user I found a fantastic free app call Convertbee and it converted pretty much any unit to any other unit you can imagine. It also did currency.
Since I switched to iOS full time I have not found a great replacement. I have been using Units Plus and went to pay for your full version, however it has not had an update in 2+ years and I worry about it being abandoned (looking at you Bean for Lemmy).
Looking for a replacement app available in the US. Thanks.
ETA: I have no issue paying for the app, but absolutely no subscriptions.
Soulver for iPad can do that. It’s very good, but expensive.

This app looks dope… or is it based? I need a gen X to z lingo converter too.
