hearWHO is a free hearing test app developed by hearX Group, available on Android devices. It is designed to help people test their hearing from time to time, especially those who are at a higher risk of hearing loss such as adults above 50 years, those working in noisy places, those listening to music at high volumes for long periods of time and those experiencing ear problems.

The app provides a screening test that measures the user's hearing ability by playing various sounds at different frequencies and volumes. The test results are displayed in a simple and easy-to-understand format, indicating whether the user's hearing is within the normal range or if there are any potential hearing problems.

It is important to note that the accuracy of the test results depends on the type of headphones used and the ambient noise level. Therefore, the results are intended as a first step in testing hearing and should not replace a complete hearing evaluation by a certified medical professional.

Overall, hearWHO is a useful app for anyone who wants to keep track of their hearing ability. It is also a great tool for promoting early identification and intervention for hearing problems.
