What is Currency?
A currency converter that works offline. You provide the rate (or use the built-in default table) so nothing depends on a live network call.
How it works
Conversions multiply the amount by the ratio of the two currency rates you set; the editable rate table makes manual updates easy.

Frequently asked questions
Why doesn't this fetch live exchange rates?
Live rates require an external API, which would send your data to a third party and break the tool's offline-first design. Paste today's rates to convert accurately.
