Purple Wallet

The right card,
before you tap.

Say the cards you carry, once. After that your phone shows the best card for whatever shop you walked into — on the Lock Screen, before you reach the counter.

The counter surface

One glance, before you reach the till.

The app has one screen, and it changes shape with how much is actually known. A clear winner looks like a winner. A verified split becomes an order to follow, one card at a time. When the evidence is thin it says so, rather than dressing a guess up as an answer.

Split deals

Two cards, one purchase, both bonuses.

The community posts ways to split a single purchase across two or three cards to hit multiple bonus categories at once. Crucially, only for shops where someone has already confirmed it works at a real register — a split that's theoretically valid but fails at the till is worse than no split at all.

Upvotes and downvotes drive a live confidence score. A deal with a hundred confirmations and three failures stays visible. A genuine coin flip is discarded rather than shown with a warning, because a warning still leaves you running an experiment with a queue behind you.

Confirmed
100 / 3

Stays live. Enough evidence, strong agreement.

Contested
50 / 50

Discarded. We'd rather show one card than a coin flip.

Not enough yet
3 / 0

Held back. Three people agreeing isn't evidence yet.

How it works

It does the work, so you don’t.

The point of this is automation. You should not be checking an app at a till, remembering which offer you activated, or working out whether the 4× beats the $75 back. The phone should already know, and the parts that can be done for you should be.

Your issuer quietly gives you offers at specific shops — spend $200 at the supermarket, get $75 back. They rotate monthly, nobody publishes them anywhere, and they are routinely worth more than the rate printed on the card. The browser extension collects them from your issuer while you are already signed in, so they end up in the answer instead of in an email you didn’t open.

And the lines that don’t move: no spend tracking — we don’t need to know what you bought. No social feed, no following, no profiles. An account is optional; the wallet works signed out and always will.

Status

Not released yet.

Purple Wallet is in active development. There's no TestFlight or store listing to sign up for yet — when there is, it'll be here. The browser extension for Chrome and Safari is built and testable now, ahead of the app.
