Hearing Test Ear Age Test is a free iPhone app developed by Yuichi Sakashita. It falls under the lifestyle category with a subcategory of health and fitness.

The app provides users with a simple hearing test that can be done at home. It is capable of testing frequencies ranging from 125hz to 8000hz and displays the results on charts. Users can save the test results and compare them over time to track any changes in their hearing ability.

In addition to the hearing test, the app also offers an interesting feature called Ear Age Test. This feature allows users to determine the age of their ears. As people age, they tend to lose the ability to hear high frequency sounds. The app plays tones up to 20000hz and assesses how far high frequency sounds the user can hear. It's a fun way to discover if your ears are younger than your actual age.

With its simple interface and useful features, Hearing Test Ear Age Test is a handy app for anyone interested in monitoring their hearing health.
