The present work reports the development of an application called Signa App, which was designed following the philosophy of User-Centered De-sign. Signa App aims to provide a mobile platform for editing and creating texts in SignWriting notation. The proposal was based on the lack of a mo-bile application that is usable for Deaf individuals who use sign language. The application was tested with adults, children, and adolescents, and the results showed a high degree of acceptance and ease of use. The app has al-ready been introduced to the SignWriting user community, receiving posi-tive feedback. Likewise, the application is available on the Google Play Store
