Importing contacts allows you to load your phone's contacts into Peerio. To import contacts, go to the Contacts tab and tap the orange + button.
Tap Search on the following screen. Peerio needs your permission to access your contacts.
Peerio will add any users with matching email addresses. For email addresses which don't have an associated Peerio account, you will be shown a list of contacts with email addresses. Tap the Invite button to send your contact an invitation to join Peerio. Invited contacts will appear under the Invited section in the contacts tab, then will be added as a favourite contact when they confirm their email address.
Importing contacts will be possible in a future update to Peerio on Windows and Mac. For now, you can import on iOS and Android.
