Life changes. Your contacts should too.
People move, change phone numbers, switch jobs, update email addresses, and more. OneContact keeps the contact information of the people you've connected with up to date, so you always have their latest details. When your own information changes, you can update it once and share only what you choose.
HOW IT WORKS
Create your custom contact cards and connect with the people who matter. As your connections update the information they've chosen to share, your contact list stays current automatically. When your information changes, simply update your card once, and everyone connected to that card receives your latest details automatically.
No more wondering if you have the right phone number. No more outdated addresses. No more sending messages to the wrong contact.
MULTIPLE CARDS FOR EVERY PART OF LIFE
Create different contact cards for work, family, friends, or any group you choose. Share only the information you want with each connection, so everyone sees exactly what you intend.
ALWAYS IN SYNC
As the people you're connected with update their information, your contacts stay current automatically. You can also choose to sync your OneContact contacts directly to your phone for an address book that's always up to date.
PRIVATE BY DESIGN
You're always in control. Connections happen only when both people agree, and you decide what to share, who can see it, and when to stop sharing.
Stop managing contacts. Let them manage themselves.
