Ratings and reviews

Just started using it. At least this app offers you premium type features under the basic, or free, user membership. Seems more professionally laid out and although I need to play around with it's setting, to make equalizer adjustments, and familiarize myself with the layout, it's pretty good.

This app works great with Samsung Ultra 23S and Shokz Bone Conduction Headphones. But there is a latency using the Bluetooth headphones. It works well for TV and Meetings where your phone can be placed in a good location. The one thing that I don't like is that the developer has no way to be contacted. I would like to switch from the monthly plan to an annual plan to save some money and I feel like the software is worth it. It would be nice to have a pathway to convert your subscription.

I'm using Galaxy S8. Right now I only have wired headphones to try with this app. With free version, I think it performs really well considering real-time sound. It doesn't lag at all in my case. I also tried 2-3 apps but they have sound lag really bad. For bluetooth headsets, I'll update again if they work the same as wired ones after I receive my order. In my opinion, it would be great if you charge only one time instead of subscription though. For the comment about this app doesn't work, my assumption is, the mic doesn't pick up any sound at all. I had this problem too. In my case, I installed other apps as I mentioned earlier and they might authorize the mic instead of this app. I fixed this issue by uninstalling all other hearing aids apps and completely closed this app. After I open this app again, it works normally. [For now]
