As answered by people managing Project Euler and Cardinate.
Cardinate's answer:
Cardinate is built card-first, not as a generic budgeting app that happens to show credit cards.
See your limit, balance, APR, and utilization for every card — not just an account total.
Know exactly when a 0% or deferred-interest offer expires before it costs you.
Choose the approach that works for you:
Sync your cards via Plaid on Pro, or track everything manually if you prefer.
Designed from day one for people juggling several credit card accounts, not just one.
No credit repair promises. No financial advice claims. Just organized information to help you understand your cards and debt.
It’s the credit card tracker for people who want to understand their debt and pay it down faster.
Cardinate's answer:
Most budgeting apps treat credit cards as one line item. Cardinate is card-first: it shows your limit, balance, APR, and utilization for each card, tracks promo-rate expirations, and offers payoff strategies built specifically for revolving credit card debt:
Cardinate is also privacy-forward — no credit-repair promises, no financial advice claims, just organized information that helps you understand your credit cards and manage your debt.
Cardinate's answer:
Cardinate is built for people juggling multiple credit cards — especially those who:
Cardinate is for people who want card-level clarity and a clear path to paying down debt, rather than another all-purpose budgeting app.
Cardinate's answer:
I started as a credit card “superuser” while planning — and paying for — my wedding. I realized I could stack welcome bonuses to help cover our honeymoon flights, and it worked. That success quickly became a habit: more cards, more points, more accounts.
Eventually, the spreadsheet I relied on to track balances, 0% APR deadlines, balance-transfer dates, and credit limits couldn’t keep up — especially once my wife started using the cards too and our transactions were spread across 10+ accounts.
That’s why I built Cardinate: the all-in-one credit card spending tracker and debt payoff planner I actually wanted to use every day.
