I finally stopped missing out on credit card discounts.

I got tired of carrying 5 cards and never knowing which one to use for the best discount at the mall.

So I built CardSense. I just added a "Live Tracking" feature where the app literally pings me when I'm walking past a store that has a promo for one of my cards.

Just walked into the mall today and got a notification for 40% off dining—something I definitely would have missed if I didn't have the app tracking it live.

If you're a "points/miles" person or just like saving money, check it out. I'd love some early testers to help me find any bugs in the proximity logic!
