# UX case study - reMarkable 2
This document is [will be] a case study of the reMarkable 2 UI.
(@DavidBoddie): The reMarkable's Codex system has a GUI that is based on Qt 5 (or maybe Qt 6 now) and seems to be based around at the core purpose of that product, which is document creation and annotation. Perhaps that will change if they support a third party app ecosystem
