Am I using the wrong credit card for my purchases? (2026)
If you use the same card for more than 70% of purchases, you're almost certainly leaving rewards behind. Multi-card wallets only work when each purchase goes to the highest earner.

Why most people pick the wrong card
Most people default to the same card at checkout — usually the one on top in their wallet. That habit quietly costs hundreds of dollars a year when another card in your stack earns 3×, 4×, or even 6× on the same purchase.
How Pikt routes smarter than guesswork
Pikt links the cards you already carry, weighs your offers and category earn rates, and tells you the best card to use — with a plain-English explanation and dollar estimate for every purchase. Online, the Pikt Checkout extension auto-fills that card at checkout; in-store, Pikt Nearby names it on your lock screen. Pikt shows how much more you would have earned versus your default card on every simulated purchase.
