Chase, Bank of America, and Credit Karma continue to duke it out for the top spot among finance apps.

In Google Play, Credit Karma unseated Chase Mobile from the No. 1 spot this week, while Bank of America fell to No. 5. However, on the iOS side, Chase retained the top spot, Bank of America stayed at No. 2, and Credit Karma fell from No. 7 to No. 8. Wells Fargo Mobile retained the No. 3 spots on both lists from last week. PayPal maintained its position at No. 5 in iOS and moved up to No. 4 on Google Play.

The most surprising dark horse app this week is HOME by Fannie Mae. According to the iOS app store, HOME is an app that guides the user through the home-buying process. It came out of nowhere to No. 9 on the iOS store list. It’s only up to version 1.0.2, meaning that it’s fairly new, and was last updated July 10. Perhaps the success of this app says good things about the housing market?

Another surprise this week was the Acorns app in the iOS app store. Acorns was last week’s dark horse in the Google Play store, coming in at No. 11. This week in the Google Play store, Acorns comes in at No. 20, but on iOS, it’s No. 16, up from not being on the iOS list at all last week.

Last week we noted Progressive Mobile’s presence on the iOS app store’s list. Well, this week it isn’t here, while its rival GEICO Mobile moved down a place in both iOS and Android to No. 13 and No. 9, respectively. (We suppose Progressive was less of a threat to GEICO than we imagined.)

And finally, we welcome a new banking app to the iOS list: PNC Mobile Banking! According to its app store profile, the PNC app is only available for PNC customers. Perhaps PNC has either begun marketing its app more aggressively, or has experienced a spike in new customers? Yesterday, Bill  Demchak, president, chairman and chief executive of PNC, told bank investors that PNC last quarter saw “primary digital channel usage” among its customers exceed 50% of its customer base for the first time. Welcome to the rankings!
