Stop guessing which credit card to swipe. OptimalSwipe tells you the best card for every purchase, privately and on-device.
Your cards and transactions live in your private iCloud Drive. Recommendations run locally using smart built-in rules and a fast Apple Shortcut. Trigger both from the app screen, or run the Shortcut directly for instant suggestions. No bank logins. No servers.
Installable as a PWA on desktop and iPhone. Maximize points or cash back.
Early, opinionated, privacy-first.
