What’s the difference between app and device contacts?

When using the app, you can view two types of contacts: From App and From Device. You can switch between them by tapping the respective buttons on the Contacts bar.

• From App: These are the contacts you create directly within the app. When you add a new contact in the app, it is saved to your From App list.
• From Device: These are contacts synchronized from your device’s contact book.

The key difference is that you cannot edit contacts imported from your device’s contact book directly within the app.
