Getting your player ready...
Have a bunch of reward credit cards but aren’t sure which card will give you the biggest reward for specific purchases? Glyph (pay ), which plans to change its name to Wisely, and Wallaby (walla.by) can help.
For each of these apps, you first enter the reward cards you own. Armed with that information, they will use the GPS on your phone to identify the retailer or restaurant you’re in and advise you on which card to use to maximize your cash back or reward points.
This can be a huge help for credit cards that change bonus-reward categories each month. Each has a companion website. Linking your cards can be time-consuming, but presumably, you do it just once. Gregory Karp, The Chicago Tribune
