The contacts list is currently quite hidden in the upper left corner. The settings are hidden in the upper right corner.
It would be better to have a tab-style interface as in WhatsApp or Threema. With the tabs at the bottom, contacts on one tab, chats on another, and settings on a third. Plus other tabs as needed. Users are more comfortable with this UI style and it is easier for them to switch :)
