If you bought a Wakeout plan through Apple, you can share it with your family using Apple Family Sharing. Every Wakeout plan can be shared this way, up to 6 family members. Here is how.
Before you start
Family Sharing works for plans bought from Apple. It does not work for gifts, because a gift is tied to one Wakeout account. See the section at the bottom.
How to share your plan
Set up Family Sharing: on your iPhone, open Settings, tap your name, then "Family Sharing", and follow the steps.
Add family members: tap "Add Member" and invite them to your group.
Turn on subscription sharing: in Family Sharing, open Subscriptions and make sure sharing is on.
On their phone: your family member installs Wakeout from the App Store, signs in, and taps "restore purchase" on the plan screen so the app finds the shared plan. See How to restore your active subscription.

Got a gift instead?
Apple Family Sharing cannot share a Wakeout gift. To give Wakeout to someone in your family, send them a gift code and they can redeem it on their own account. See How to Gift and Redeem Wakeout Subscriptions.
