Let us help you make your apps accessible

Abra focuses on making accessibility straightforward, enabling developers to make effective improvements.

We would love to help you improve the accessibility of your apps. We provide consulting, assessments and training. We develop accessible apps ourselves, so we know what we’re talking about.

We are also the founders of the Appt Foundation, a non-profit organization aimed at sharing free knowledge about building accessible apps.
