Although mobile devices include accessibility features available for visually impaired users, the user interface of the majority of the mobile apps is designed for sighted people. It is clear that "Design for Usability" differs depending if the final user is a sighted user or a visually impaired user. This paper introduces the concept of "Low Vision Mobile App Portal", which provides a way to access mobile apps specifically designed for visually impaired users. Some design aspects will be described. Preliminary results show some of the low vision controls specifically design for visually impaired users.
