I carry a handful of premium credit cards. Each one has different reward rates, different bonus categories, different statement credits that reset on different schedules. On paper, a great setup. In practice, I was constantly guessing which card to pull out at checkout and forgetting to use credits before they expired.
So I looked for something to help. And everything I found made the problem worse. The apps were bloated with features I didn't need. They were full of ads and promotions. They made bank linking part of setup and put a long onboarding between me and anything useful. Once I was in, there was a steep learning curve just to figure out how the tool worked. None of them focused on the simple thing I actually wanted: know which card to use, track my credits, and ask a question when I need to.
Every tool I tried was optimized for the tool maker, not for me. More data collected, more features to upsell, more friction to lock you in.
So I built Cardzen. Something simple that works. You tell it which cards you carry, without connecting a bank or entering card numbers, and in under a minute you're set up. Ask which card to use at a store, mark a credit as used, check what's expiring. That's it. No noise. Just the stuff that actually matters.
If you carry more than one card and you're tired of tools that make a simple problem complicated, Cardzen was built for you.

Points. Credits. Answers. That's it. Cardzen doesn't try to be your budgeting app, your credit score tracker, or your financial planner. It does one thing and does it well: helps you get the full value out of the cards you already carry.
Most credit card tools make money by pushing you toward new cards. Cardzen doesn't. There are no ads, no sponsored recommendations, no affiliate links. The only goal is helping you get more value from the cards you already carry.
Setup takes under a minute. The interface is a chat. Ask a question, get an answer. Mark a credit as used, done. If you've ever texted a friend for advice, you already know how to use Cardzen.
