The GhSL Dictionary app is designed to help GhSL learners learn and acquire knowledge of Ghanaian Sign Language. It is advantageous for GhSL learners to communicate with the deaf with ease, and it helps teach babies and children how to talk if their families are deaf or hard of hearing. The GSL app also helps people connect themselves with the deaf and hard-of-hearing people in the community. GhSL Dictionary is free, along with ads integrated into the app. The GhSL Dictionary app includes sign videos that can be viewed online or offline and quizzes for learners to answer questions and improve their GhSL skills fast. You can download all sign videos for offline use (in-app purchase). We keep shooting new sign videos and uploading them to a remote server that charges a lot of money. GhSL learners will always get the new sign videos when their internet is active. Thanks. Mr. Leslie Okyere is a software developer and is deaf.
