Many of you possess more than one credit card, either linked to an airline frequent flyer program or one that offers a wide variety of perks and bonus points or statement credits triggered for restaurants, gas purchases, home improvement stores and more. 

But which card should you use for which purchase? There’s now an app — it’s called CardPointers and it tracks more than 5,000 cards across more than 900 banks. 

That app can tell you which credit card to use for every purchase to maximize your points and bonuses. It also tracks all merchant offers and when your bonuses or statement credits may expire. It’s got a $90 annual fee, which can be recouped by identifying those bonuses and savings on the cards.
