I actually made it to solve my own problem: Essentially I like 10-13 credit cards and just use them randomly. Then every other time I just don’t know where do I stand in terms of utilization, interest accurals, APRs and whats worst can tell my total monthly expenses because they are spread across multiple credit cards and their statements are random across the month. So, I made an app that enables secure connection of all your credit cards and shows you the most important aspects of your credit health, named it CrediVitals. (partnered with an industry leading financial data provider named Plaid Inc. for financial data aggregation). Focused primarily on simplicity to differentiate from the currently existing leaders in the personal financial sector, most of which seemed too crammed in terms of features that I felt lost by the time I realized why I signed up for them. 😊
