The idea
One crown instead of a stack of cards
We all end up with a pile of cards: debit, credit, rewards, family. CardDog doesn't add another one — it puts you at the head of them all. One calm place where every card and every dollar is in plain sight.
- All your cards at a glance, with no app-switching
- You control spending and limits, not the bank
- A quiet interface with no banners or pushy ads
