Obvious technical issue. NO SOUND
I wish you would change your description about no sound above and acknowledge that there is a problem with your app and you are working on a fix. It has nothing to do with the hardware on my phone. I deleted and reloaded. Its not my fault, its yours. Fix this app or start giving refunds and discontinue. The way it it now, you are simply taking money for something that is obviously defective. That borders on fraud.
I have the video and think the method is great. I would be a great promoter of your product if you would fix this app.
