Good credit app?

Jurckie Backhart

What app do you use to keep up with your score? I have a discover card and it shows me my FICO score but when I went to buy a car it was a couple points lower than what Discover was showing. Also, I cannot use Credit Karma because they locked me out for inactivity and I cannot log back in. I emailed them and couldn’t get it resolved so please any other app? Thanks!
