Works but cuts out within seconds when sound is low – Megaphone: Voice Amplifier Review

I purched the full app in order to (now, don't laugh) see if I could hear the fruit I just ate being broken down in my stomach, and I can, but because the gurgling sound is relatively low, the mic cuts out quickly and I have to make louder sounds to wake the mic up. A workaround is to move the phone, creating a friction sound loud enough to keep the mic active. As long as this is done before every ten seconds elapses, the mic stays on. Therefore, I'm mostly happy with this purchase. The gurgling sounds are somehow soothing to me. Womb sounds. I can also listen to my heartbeat using this app. Thanks!
