Stop leaving cashback on the table.
For any store, CashCatch tells you the single best card to pay with — and the cashback portal to stack on top — so you squeeze every percent out of every purchase.
It stacks
Most tools just pick a card. CashCatch combines your card's rewards and a shopping-portal bonus into one optimal play.
Runs on your device
Your wallet never leaves your phone or browser. No account, no sign-up, nothing sent to a server.
Right when it matters
Online at checkout or tapping in-store, you get the answer in a tap: which card, plus what to click.
Free to use
No subscription. We earn affiliate commissions when you shop through our links — never from your data.
How it works
Add your cards
Pick the cards in your wallet once. Stored locally on your device.
Shop anywhere
CashCatch recognizes the store and checks your cards against live cashback rates.
Earn the max
See the best card plus the stack — e.g. Rakuten 3% + your card 2% = 5% back.
