Quite nice to see that this is written in Haskell.
The idea of a bitcoin app that stores funds in another currency makes a lot of sense for people who primarily want to use bitcoin as an exchange mechanism without speculating on its future value.
I'm curious what service this uses to purchase bitcoins, or if it uses its own exchange; it's not comforting to see a reference to the MtGox API, but hopefully they're only used to find out the current value. (Even then, they're not a reliable metric for the true value of bitcoins, since they're not sufficiently liquid with respect to governmental currencies, but that'd still be better than actually attempting to use them as a currency exchange.)
