Hi all, I’m a long time holder of CSR and credit card enthusiast. I created an app to make managing my credit cards more enjoyable. Spreadsheets were ok but I wanted to improve on the experience with a native mobile interface and use the data to create visualizations and gain insights about my portfolio from basic things like am I breaking even on annual fees to more random things like have I earned more ultimate rewards points from sign-ups than membership reward points. I also wanted the app to be able to capture more niche things like product changes and lounge visits. The app is called Cardsy and you can find it in the Apple App Store (no android available yet) if you want to give it a try. Open to any feedback and suggestions.

I've been in the credit card game for a bit and have been using a spreadsheet as I'm sure many of you do to track everything related to my cards. I didn't find existing options able to fully replace my spreadsheet. Since credit cards are one of my biggest hobbies I wanted to try to build something that could organize all the stuff I care about (bonuses, lounges, category multipliers, credit line history, credits, awards), be more enjoyable to use than just entering data into spreadsheet cells, and also be able tie all that data together to create visualizations to see all the value I've gotten from holding my cards.

If anyone is interested in trying it, it's called "Cardsy: Credit Card Tracker" on the App Store. Appreciate any and all feedback.
