Top (free) financial apps for Android

A little off topic (or not) but I'd like to share my excitement when I found that most major banks (and Canadian top 5 banks) have free financial apps for their customers. It's probably obvious and one could argue that the app is not actually free since you need a bank account. But since even King Kong has a bank account these days, it's probably worth checking out the apps before expending too much money on a paid one that does the same thing.
