It has received positive feedback from users, with many expressing how it has positively impacted their communication with their loved ones. Doctors also trust this app, as it has been recommended to nursing/CNA staff for use with senior patients who have hearing loss.

Overall, Hearing Helper is a simple and user-friendly application that provides real-time speech-to-text translation, making it easier for individuals with hearing difficulties or language barriers to communicate effectively.
