USAA continues to make improvements to its mobile banking and account management app today with several UI and bug fixes. An important fix was made to let users on Jelly Bean properly log in and use their PIN with the app, and another bug that kept users on Android 3.1 and higher from doing person-to-person transfers. USAA has also now added the ability to fund an account when you create one from the app -- an interesting feature -- by scanning a blank check from another bank.
You may not be a USAA customer (yet) but the app is definitely worth a look if you are. You can grab a download at the Play Store link above.
