Pool has four member roles: Owner, Admin, Spender, and Viewer. The Owner is the original member who started the Pool. Admins manage member roles and permissions.
How permissions differ
Member roles and permissions are usually not available with traditional joint accounts.
When Pool may be useful
Pool can be used by couples, families, roommates, friends, and groups who want a simple way to organize shared money, track activity, and make purchases related to a shared purpose.
Many people use Pool because they want the benefits of managing money together without the commitment, complexity, or permanence of a traditional joint account.
