This started as a personal project because I desperately needed an app to manage all 12 of my credit cards. I tried a couple of apps on app store but they were either too sophisticated for a simple task or simply doesn't do what I want.
So I decided to take up the challenge, and created a simple app that basically helps me to keep track of payment due dates and transactions.
Free version is available and it is fully functional. Pro version adds a couple of less essential features that makes the app even better, if you like the app you may purchase the Pro version to support further development of the app :)
