  Credit Karma for Android is completely free, and all of the
services it offers are free as well. You can check your credit
score as often as you like (Credit Karma pulls its data from
TransUnion, one of the three big credit reporting companies) and
monitor your overall credit rating at any time. You can see your
credit "report card," which gives you a broad overview of your
credit history and its health, and then drill down if you want
more information on anything specific.  The app comes with free
credit monitoring, and shows you any alerts on your account,
like hard credit inquiries (the kind that can at times damage
your credit rating) or if any new accounts have been opened in
your name. You'll also get push notifications any time something
changes in your credit report, just so you can stay on top of it
and act immediately if you're worried someone has stolen your
identity. For security, the app can be PIN locked. You can grab
it at the link below.  Credit Karma Mobile | Google Play via
