What's New in CardKeep
1.0.20
August 16, 2026
What's New in 1.0.20 • Text your guests right from their contact card — see the full message history, reply inline, and get a badge when there's something new to read, plus a checkmark once your text is delivered. • New filters help you quickly find contacts missing a phone number, who've opted out of texts, or haven't RSVP'd yet. • Mark an RSVP manually when a guest calls or tells you in person — no link needed. • Shared lists are smarter now: anyone you've invited to help can see RSVP status at a glance, and editors can record responses too. • Fixed a sync issue that could occasionally revert event details or contact info when switching between devices. • Tip: Prefer a bigger screen? Everything in CardKeep is also available at app.cardkeep.cc — manage your list, RSVPs, and collaborators from any browser, fully synced with the app.
