I'm Andrew, MeetVault's maker. A scanned business card tells you who someone is. The part worth keeping is why you met and what happens next.
My suggested after-event workflow: scan the card, add a short note about the conversation, set a follow-up reminder and keep the context with that person. Before the next meeting, Purpose Search helps you find relevant people in your own network.
MeetVault also shows the network visually, with 3D and 2D views. Card scanning and local notes work without a forced account; optional account features are separate.
It's live for iPhone and iPad. The App Store lists a 7-day full-access trial, then a free first card or paid Pro for the expanded toolkit: https://apps.apple.com/app/id677...
