Does not work

This app used to be my favorite ukulele tuner app! Recently it stopped working. The app opens but it doesnt show any indication that it is receiving any sound. At first I thought it was my phones microphones fault, so I tried plugging in my earphones to see if it would register anything with that on. Still nothing. With all hope lost, I went to see if it was just my phone not recording sound, but on my video, the sound goes through fine; pointing to only one thing. This app does not work. Such a shame too. It used to work wonderfully.
