Yes! The Premium and Youth Member Areas feature "responsive" programming, so they look good on a desktop, laptop, mobile phone or tablet... really any sized device or screen. Since they are online memberships, you must have an Internet connection (e.g. wifi, cellular, cable, etc).
The Deluxe Playbook download only works on computers as it must be downloaded as a zip file and then "unzipped".
A USB drive product (Deluxe USB, Players USB, Combo Special, Ball of Wax) must be plugged into a USB port.
