Bests & Worsts Reviews from Amazon

I bought this to use it for my dog because she has heart failure and I wanted to recored her heart sounds every several days and send it to my brother because he is a cardiologist but lives in another state to know when she has fluid in her lung to increase her furosemide dose. Unfortunately, after I recorded the sound and saved it, I couldn't find any way to share the file with my brother because the app doesn't let me to save the file on my phone. The only way to send the clip to my brother is by activating the live stream. When I tried to activate the live stream the app says I need to upgrade my plan to use this feature, and when I went to the website to check the prices, I found there were two plans one starts $50/month and the other $200/month.
