Timblee is used to plan digital experiences for websites, mobile apps and web apps. "Pages" is a term used mostly to refer to pages on websites or web apps (sometimes) but mobile apps are completely left out with the term "pages".
As Timblee is being used more and more by UX designers and project planners working on both web and mobile experiences, we believe the more universal term – 'screens' reflects this more accurately.
While it's a small change, we believe a commonly understood shared terminology is critical to reduce friction and improve clarity between teams, and between us as product creators, and our customers.
From this point on, if you're an existing Timblee user, you'll start seeing this change being rolled out through the interface.
