The difference between the app contacts and the phone contacts

While using the app, you can view two kinds of contacts: App Contacts and Phone Contacts. You can switch between them by tapping on the respective buttons on the Contacts bar. When you add a new contact within the app — it is added to the list of App Contacts. So, App Contacts are any contacts that you have created within the app itself. On the contrary, Phone Contacts are contacts that have been synchronized with your iPhone phone book. The difference between them is that you can’t edit those contacts, which have been imported for your iPhone Contacts.
