Because the NuCalm Package includes a lifetime subscription for a user, it only comes with a one device license. However, if you'd like to share it with other members in your household, you could just as well put the app on an iPad/tablet or old phone so that the app could be used by anyone or taken with anyone at any time. Should you later decide that you would like to add more devices, you can reach out to us to discuss another purchase or family plans. I would recommend starting with one to assess your needs.
The lifetime subscription is great, because we do intend to eventually offer a subscription model so NuCalm can be more accessible to more people. Anyone who has purchased before then will automatically be assigned lifetime access to the highest level of subscription in the new app.
