The Mint.com app has received a solid update today with lots of background improvements and a couple of forward-facing fixes. One of the biggest improvements in this update is the ability to update in the background every 4 hours. While we'd prefer a customizable update schedule, background syncing is a big step in the right direction. The other improvements are all about speed -- Mint is claiming faster transaction downloads and overall load times, along with a quicker way to categorize transactions on the phone interface.
And the update wouldn't be complete without the nondescript "bugfixes" as well. You can grab a download of -- or update to -- the Mint Personal Finance app at the Play Store link above.
