Want to guess how many unredeemed frequent flyer miles are out there? Would you believe 23 trillion?

And chances are some of those are yours.

How about unredeemed frequent stay points? The number is also in the trillions. It’s not only getting harder to redeem them, but also hard to track them.

But now, some apps help you stay on top of your points and miles.

AwardWallet is a great app for tracking all your airline, credit card, and hotel reward points and miles – and it tracks nearly 700 loyalty reward programs. Most importantly, the app features a spending analysis tool that tells you whether or when you are maximizing your rewards.

MaxRewards is another app that specializes in bank and credit card loyalty programs and can tell you which card is the best to use before you make a purchase.
