Tell it what is in your wallet. At the till it names the card that earns you the most on that purchase, after the monthly cap you have already used and the foreign-currency fee. A calculator for cards you own, not a bank connection.
Ranked on the device, offline, before you reach for your wallet.
Category is a guess, not a fact.
A coffee counter inside a supermarket
bills as grocery, not dining.
Caps come from spend you log,
not from a bank feed.
Abroad, the 2% card is the worse card. PayperWIZ ranks on the net rate, so it never recommends it there.
This is the one people get wrong
every single holiday.
You arrive. It names the card.
An exhausted card stops winning.
Net rate, not the headline one.
Progress, deadline, two reminders.
Drafts the reward table, with sources.
Cards, spend and location never leave.
Most bank offers are published nowhere a program can read. Where it is unsure, it says so.
No linking, no transaction feed, no Open Banking. What you type, and roughly where you are. That is all of it.
Every rate shows where it came from. A card with no reliable source ships with no rates at all.
Cards, shops, prices, currency and clock all follow.
Every card in the catalogue for a country, ranked by what it really returns on each kind of spending — with the caps and minimum spends that decide whether a headline rate is real.
The cards somebody has actually read off the issuer's own terms have a page each, with the cap, the minimum spend and the date it was read. Every checked card, by market. Ireland in full: every credit card in Ireland, read off the issuer.
Credits cover only the two operations that cost real money to serve. There is no subscription.
Credits are consumables and never expire. Prices are shown in US dollars. The App Store charges in your local currency, at Apple's tier for your market. Once a card's published terms have been researched by anyone, the answer is cached and served to everyone else in that market without spending a credit.
Four cards, one of them very good at groceries, another very good abroad, and no way to remember which was which while standing at a till in Dubai. That is the entire origin of this app.
An early build could not find a small cafe a few streets away. Two days went into assuming the maps data was wrong, before it turned out the search had never been told to look nearby. Everything here is made of small, specific problems like that one, and the app is better for each of them having been found the hard way.
