You can import contacts from your Contacts app into the Grasshopper Connect app. Also see How do I add a new contact?

  1. Tap Contacts in the lower toolbar.
  2. Tap the blue Add icon in upper toolbar.
  3. Tap Import Contacts.
  4. Select all the contacts you want to add, then tap Add Contacts

Please note that importing contacts is a one-way sync; any updates you make to a contact in the Grasshopper Connect app will not impact the corresponding entry in your Contacts app (and vice versa).
