Phone Sync

How Phone Sync works.

Your Circles appear in the Contacts app on your iPhone, Android phone, Mac or Outlook. Add someone once and they're on every device within minutes, and when they call, their name and company are already on the screen. Included on every paid plan.

Set it up

Three steps, once per phone.

Phone Sync uses CardDAV, the same open standard your email account already uses for contacts. It's built into iPhone, iPad and Mac, and one small free app adds it to Android.

Phone Sync in the app: two phones, and the U.S. Government Circle going to them by group
1. Choose what goesIn the app, open Phone Sync and pick the Circles, groups or favourites for this phone.
2. Add the accountOne screen on the phone: a server address, your email and a password the app makes for that phone. Two minutes.
3. Forget about itChanges appear within minutes. Someone new you add on the phone waits in the app until you choose their Circle.

The moment it pays off

An unknown number stops being unknown.

Because your Circles live in the phone's own address book, every part of the phone knows who's calling: the lock screen, the call log, the text messages, the share sheet.

  • Name and company on the lock screen, before you answer
  • Your call history stops being a list of numbers
  • Texts from the school or the plumber arrive with a name on them
  • Your Circles sit alongside what's already on the phone; nothing there is touched

What goes to your phone

You decide, for each person and each phone.

A whole Circle

Everyone in it.

Certain groups

Only the groups you pick, like Clients or Family.

Favourites

The forty people you actually call, alone or within groups.

Birthdays can come along or stay off. Your phone and your spouse's phone don't have to carry the same thing. Lost a phone? Revoke that one device in the app; the others are untouched.

One-way or two-way

One-way by default, on purpose.

One-way (the default)

Changes flow from My Contact Base to your phones. An edit made on a phone doesn't touch the shared record, and the phone goes back to the shared version. Right for anything more than one person relies on.

Two-way (you turn it on)

Add a number on your phone and it appears in the app. Turn it on per Circle. A delete on a phone never deletes anyone by itself: the app asks you first, and every change a phone makes is recorded.

Bring your contacts in Coming soon

Copy what's already on your iPhone, from the phone itself.

Apple gives you no way to export contacts in bulk from an iPhone. Our free Migration Tool does it: sign in, pick a Circle, see what's new against what you already have, and copy it across into one group. It never changes anything on your phone.

Coming soon to the App Store · free on every plan, including Free.

Android

Contacts app → Manage contacts → Export → save a .vcf file, then import it into My Contact Base. No computer needed.

iPhone, from a computer

iCloud.com → Contacts → Select All → Export vCard. Or export from Google Contacts, then import the file.

A file you already have

Any vCard or CSV from Outlook, a spreadsheet or an old system. The import maps the columns for you.

However you bring them in, duplicates are matched on email first, then on name plus company, and you see every proposed merge before anything is combined. Each import gets its own group, so a bad one is one click to undo.

Common questions

About Phone Sync.

Do I have to install an app?

Not on iPhone, iPad or Mac: CardDAV is built in. You add an account in Settings the same way you'd add an email account. On Android you add one small free app, DAVx⁵, and your Circles appear in the phone's own Contacts app.

Will it overwrite the contacts already on my phone?

No. Your Circles arrive as a separate account, alongside whatever is already there, the same way a work email account's contacts do. Removing the account removes only ours.

What if I lose my phone?

Revoke that device in the app and syncing stops. Each device has its own password, so revoking one doesn't affect any other and you never have to change your own login.

If I add a contact on my phone, does it come back?

Yes, but it never lands in a Circle on its own. Someone new you add on the phone waits in New contacts until you choose their Circle in the app. Add them inside a two-way Circle on the phone and they go straight into it. Someone you delete on the phone is kept until you say so in the app.

How many devices can I connect?

As many as you like, on any paid plan. Each gets its own password.

Is it included in the free plan?

No. Phone Sync comes with every paid plan, and every paid plan starts with 30 days free, so you can try it on your own phone first.

What happens to my contacts if I leave?

They stay on your devices, in your phone's own address book. You can also export everything as vCard or CSV.
