About the product

CardJar keeps your loyalty cards on your phone. No account, no sign-up, no email address. Not now, not later. Open it at the till and the barcode is there, network or no network. The app sends nothing anywhere. It works in aeroplane mode because your cards are simply there.

For product owners

Promote CardJar

Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps CardJar in front of people instead.

  • Back in the X and Threads rotation: CardJar gets posted again instead of once.
  • A promoted slot on the AppRater homepage, carrying a Promoted badge.
  • A direct link to CardJar from a DR45 site (Ahrefs Domain Rating), with no redirect in between.
  • A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
  • Stays on the first screen however old the listing is, while new submissions push everything else down.

Quarterly promotion

$35USD every 3 months

Card, Apple Pay and more, through Whop. Starts straight away.

  • Cancel any time from the Whop account you paid with, or email [email protected] and we will do it.
  • The promotion starts straight away, no waiting on us.
  • Whop handles the checkout. We never see your card.

Questions first? Email [email protected].
