Your contacts, synced across every account

Sound familiar?
Google syncs to Google. Apple syncs to Apple. Nobody syncs to everybody.
One contact list, synced across every account.
Add a contact in any account and it appears in all of them. Change a number in one account and it changes in the others.
Simple to use.
Syncing and duplicate detection run in the background. You review the results and approve them.
From scattered address books to one clean list.
Connect your accounts.
Google (Gmail and Workspace), Microsoft (Microsoft 365 and Outlook), Apple iCloud, or any CardDAV server. Start with one account and add the others whenever you like.
- Set each account to read-only or two-way
- Sync only the labels you choose
- Pick a primary account whose values are copied to all other accounts
We find and merge duplicates. You review the unclear ones.
ContactZapp finds duplicates within each account and across all of them. If you let it, it merges the clear matches automatically. You review only the ones it is not sure about: the records side by side, with a proposed merged contact.
- Let ContactZapp merge clear matches automatically, or merge them all in one click
- Every phone number and email is kept. Pick a different value or type your own.
- Click “Don’t merge” once and that pair is never suggested again
One person. One record. Everywhere.
Each person appears once in every account. Change a contact in one account and the change reaches the others.
- Every sync is logged, so you can see what changed
- See which accounts each contact is in
- Labels, notes and all phone numbers are kept
Undo any change, for one contact or all of them.
ContactZapp records every change. Pick a moment and go back to it. Everything after that moment is undone, in ContactZapp and in your accounts.
- See what a roll back will change before you run it
- Roll back one contact to any moment in the last 12 months
- Or roll back one account, or everything
See what every sync did, account by account.
Follow each sync live, then read a plain summary when it finishes. If an account needs attention, ContactZapp tells you which one and what to do.
- Live progress while a sync runs
- A summary for every account when it finishes
- Every run of the last 30 days in the sync log
Your contacts are safe.
You can track everything that happens to your accounts. All your contacts are backed up and encrypted.
Your contacts are encrypted
Your contacts are encrypted and private. Only you can see them.
Restore deleted contacts
Deleted contacts can be restored for 30 days. When you are sure, erase them for good, from ContactZapp and every connected account.
Leave whenever you want
Take everything with you, in standard formats. Then erase it everywhere.
