MosquiTone is an application for measuring the age of your ears by which frequencies you are able to hear. Set one frequency range to 2000hz and listen. The frequencies you can hear shows your age. If you can hear tones at 12,000Hz, your ears are equal to that of a teenager. If you can hear higher tones, your ears are like that of a dog. The higher the tone you can hear, the younger your age.
