CardKeep: Address Book is a calm, simple way to save and organize mailing addresses for the people you care about.
Instead of spreadsheets, notes, or digging through old emails, CardKeep lets you add addresses the moment mail arrives.
How it works:
• Scan an envelope or address label
• Review and fix details before saving
• Organize addresses into lists like Family, Friends, or Holidays
• Keep everything ready for cards, invitations, and announcements
• Create events, such as weddings, graduations, etc.
• Send out requests for addresses, allow guests to RSVP.
CardKeep is designed to be private and easy to use. No clutter. Just your address book — ready year after year.
What's new (v1.0.12)
Event Card
The event card is now prominently displayed above your contact list, with quick access to QR codes and your RSVP link.
Guest Cap
Set a maximum headcount for your event. Guests see how many spots remain, and the RSVP page closes automatically when you're full.
RSVP Toggle
Pause RSVPs with a single tap. Guests who open the link will see a polite "RSVPs closed" message.
Event Photo
Add a hero photo to your event. It appears full-bleed on both the RSVP and address collection pages your guests see.
Address Collection Improvements
The "Collect Addresses" shortcut on the home screen now works correctly — tap it to instantly share your address collection link. You can also hide the venue on the collection page if you're not ready to announce the location yet.
