No, you only need one Liteboxer Membership for your family. A single membership is tied to your Liteshield and therefore supports access for everyone who will be using that particular unit. With a single Liteboxer Membership, family members and guests can create their own accounts within Liteboxer’s App. Each account profile contains distinct workout history and performance stats so everyone can keep track of their individual progress.
To add a separate user under the same Membership, click "Add Profile" on the Liteboxer app login page, then tap "New user" to create a new profile.
