MathMelodies 2: a Mobile Assistive Application for People with Visual Impairments Developed with React Native.

Cross-platform developing techniques have been attracting lot of attention in the last years, especially in the field of mobile application, because they enable the developers to code apps in a same programming language for different platforms (e.g. iOS and Android). One well-known framework for cross-platform development is React Native that presents some features to support accessibility to blind or visually impaired (BVI) people. However, to the best of our knowledge, the accessibility of applications developed with this framework has not been systematically investigated. In this contribution we report our experience in the development of MathMelodies 2, an application that supports BVI children to study mathematics. The former version of MathMelodies was developed with native code for iPad only, while MathMelodies 2 was developed with React Native to run on both iOS and Android smartphones and tablets.
