As of today you can use your Apple ID to sign in on GA Kneeboard. If you already have an account associated to Google, your existing templates will NOT be visible across accounts. Let us know via feedback whether stitching accounts would make your life easier.

Similar to Google, GA Kneeboard will call you by your first name as defined in your Apple account. Email and Name are the only two piece of information we collect for content personalization.

Using an account allows us to store templates in the cloud and deliver them across devices, as well as enabling all data sharing features. Have at it: https://kneeboard.ga
