This app is janky, and considering how much $$$ CapitalOne has at it's disposal, there no good excuse. It freezes up with every use. You need to keep signing into your Capital One account. And it doesn't auto-populate the newly created card into the online shop. You need to copy and paste it all manually from the CapitalOne website. It has not been updated for A WHOLE YEAR, so who knows if it's secure.
