The Mint app supports an additional passcode lock, as do many other banking apps with a semi-persistent login. I haven't tried GoBank's app but they probably have something similar. I wish more apps support multi-level authentication to support this at-a-glance information. I'm perfectly fine with my balance being only behind a 4-digit passcode, but transfers should require a recent full password auth. That being said, designing and implementing such a system securely is easier said than done.
