Shared ideabooks are not supported yet on the iPad app. They will be supported in the next app version, coming real soon.

Thank you!

Viewing shared ideabooks are supported in the latest version. In my houzz tab, you will see your own ideabooks as well as ideabooks shared with you. If they were shared as editable, they will also show up as options when adding to an ideabook.

Note: Sharing your own ideabook with someone still requires the web site. This is planned for a future release.
