Used this for ages to measure mechanical frequency. Now says 11098Hz whatever I try to measure.

This is wonderful app. More useful in engineering parlance. Musical notes, voice can hv many modulations. But there are applications where this is very useful. Phone microphone quality, distance can influence results greatly. One need to take 5 to 6 readings and choose the one most repeated. Awesome app.
