Welcome, and thank you for posting here in the Roku Community, @Rjarrell23!
We will be pleased to assist you with your query.
All you need to do is sign into the same Roku account you made in order to view the live recording of the same camera on two separate iPhones.
Let us know if there's anything else we can be of assistance with and we'd be more than happy to continue doing so. Hope this helps!
Best regards,
Carly
