Why you'll want it
Keep the app you know
Your connections appear in your phone's own contacts, so you call and text them from the apps you already use.
No more outdated numbers
When a linked connection changes a detail they share with you, the contact on your phone updates by itself.
You stay in control
Sync is off until you switch it on. You choose which contact each connection links to, and which details go where.
How it works
01Switch it on
Turn on contact sync in the app's settings and allow access to your contacts. That's also where you choose which details go where.
02Link your connections
allme suggests the matching contact on your phone by number, email and name. Pick it, search for another, or create a new contact — or sync everyone in one go.
03They're in your phone book
What they share with you lands in the right fields of your phone's contacts — number, email, address, photo — and stays up to date.
What sync writes
Sync only writes what a connection shares with you, and only to contacts you've linked. It adds and updates details but never deletes anything from your phone book — unlinking keeps the contact. A small allme marker on the contact keeps the link, so the same person isn't added twice. Contact sync is in the Android and iPhone apps; your links are stored on that phone.

Does allme upload my phone's contacts?
No. Sync writes into your phone book; your phone's contacts are never uploaded or stored by allme.
What happens if someone stops sharing a detail with me?
The detail stays in your phone book. Sync adds and updates details, but it never removes anything.
Can I choose which details are synced?
Yes. In the field mapping you choose where each detail goes in your contacts, or not to sync it at all. You can also keep an empty value from overwriting a field you filled in yourself.
Which account are new contacts saved to?
Your phone's default contacts account, unless you pick another one in the app's settings.
Does it work on the web?
No — a browser has no phone book. Contact sync is in the Android and iPhone apps.
What about companies I'm connected with?
A company becomes one contact on your phone, with its logo and the details each of its services shares with you.
