Great potential. Keeps crashing when trying to use the adaptation course. It worked initially but I haven't been able to continue with it. I have been testing this app to find something for my Dad who lives alone and gets less auditory interaction. I was hoping to implement this app and the course with him. Thank you for your assistance.

Have found petralex to be incredibly helpful in a time of desperation and need. Among the 20-30 hearing aid apps I've downloaded, I continue to return to this one as it's most definitely the best! Although I wish the noise suppression option would be somewhat included on the free app because after using it in the trial, without it the sounds are incredibly muffled and mixed together, very difficult to discern between for certain which noise is what. Please make the noise suppression included!

I 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!
