Version 3.3.1
sound_and_musicperformance_and_bugsI have otosclerosis with tinnitus. This app works better than any real hearing aid device that I've used. Using the microphone on the phone, rather than the headset, is genius. The phone then becomes a remote mic that, for example, I can place in the center of the boardroom table during meetings. The slight audio delay is mildly disconcerting, but not enough to lose a star!

Version 4.4.4
cross_platform_consistencylocalizationmonetizationThis 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.

Version
monetizationIt's probably a good app and service. The other reviews are very positive. However we never got to a proper subscription as this felt too intrusive. Make a annual payment? The agreement is now valid for 10 years. One of the other options went through Google pay and wanted pictures of cards. Regardless of how normal or standard that may be, we will never do that. So as much as this should take care of your need, consider whether you don't mind this intrusion.
