RelayBook
Shared address book
Only for iPhone
Free
iPhone
Keep every contact your team or family shares in one place. Add someone once and everyone in the book has them, on the web and on your phone.
RelayBook is the shared address book for teams and families.
Add a contact once and everyone you share the book with sees it instantly - no more forwarding contact cards or asking "what's Sam's new number?".
- Keep separate books for work and personal life, and switch between them in a tap.
- Organise contacts with labels, stars and your own custom fields, then filter by them.
- Log calls, meetings and notes against a contact so everyone knows the history.
- Review new contacts in your Import Inbox before they reach a book, including ones you forward by email.
- Spot and merge duplicates.
- Sign in with Apple, Google or email.
Your RelayBook account works on the web at app.relaybook.io too, so your books stay in sync everywhere.
