Only for sending iMessage attachments – William Hogarth Artworks Stickers Review

FYI: this app only provides 'Stickers', which turns out to mean attachments for iMessages, to share with your friends. This was unclear when I bought it (via an iPhone; I notice the iPad App Store does state "iMessage only"). It seems to work fine, but as I wanted a freestanding app which showed the paintings when I was offline it's useless for my purposes.
