iPads: iPads can't create or join an Analog Zone on their own — that has to happen on an iPhone first. Once you've set it up from a phone, you can download the Analog app on the iPad and log in with the same account. Note that if a child uses the iPad, you'll want to create an Analog account for the child first and log in with the child's credentials, not the parent's.

Apple Watch: Apple Watch isn't independently supported, but if it's paired to and mirrors an iPhone with Analog set up, it will follow that iPhone's app limits. The app restrictions pass through the phone.
