Credit Card Max
Tells you which credit card to swipe for the most points or cash back, using your live card data through Grok Finance.
Problem
With several cards it's hard to remember which one earns the most where, and statement credits quietly expire unused.
Solution
It picks the best card for each purchase based on your priorities, tracks statement credits with reminders before they expire, flags recurring charges on the wrong card, and sends a monthly points and perks rollup.
