Hearing assessment plays a vital role in the early detection and management of hearing impairments. Conventional audiometers used in clinics are often expensive, bulky, and require skilled professionals to operate. This paper presents the design and development of an app-based digital audiometer that offers a portable, low-cost, and user-friendly solution for basic hearing screening. The proposed system integrates a mobile application with calibrated earphones to generate and control test tones of varying frequencies and intensities. The app records user responses to produce an audiogram, indicating the hearing threshold levels for each ear. The system eliminates the need for specialized equipment while maintaining acceptable accuracy for screening purposes. Such an approach enables hearing tests to be conducted conveniently in remote or home settings, thereby improving accessibility and encouraging early diagnosis of hearing loss.The proposed system consists of a mobile application integrated with calibrated earphones or Bluetooth headphones to produce pure-tone signals across standard audiometric frequencies, typically ranging from 250 Hz to 8 kHz. The application adjusts sound intensity in controlled steps, allowing the user to indicate when a tone is heard.
