The app works mostly fine. But stay away from this card. It will work great the first month, then suddenly any and all transfers take 3-5 business days, instead of their previous Instant. On top of that, the card will charge you for being linked to any other card, and will also give a frustrating amount of headaches anytime you try to use a vending machine for a quick snack, which will leave you with a lock on your funds and no food on the go. Great card, if you hate yourself.
