My quality of life has taken a hugh downturn. I used to have hearing aids and I really miss having them because now either I feel lost, confused, or even left out not being able to hear. When I do ask someone to repeat themselves I feel like it's bothersome. I'm excited to try this app so far with the free version the test results were right on spot. The software adjustments after testing seem appropriate but may need a little more tweaking to refine some tones/echoes/playback delay.

I Love the Petralex app. With this app, you uncancel any noise, noise that you weren't even aware of. The adaptation course is My favorite part, it's like learning the alphabet from sounds around us. Hands down, 5 stars, but 4 stars because I am waiting for the update to fix the adaptation course crash. I paid and intend on paying for a long time to come. The team is very responsive when I voiced my concerns about the adaptation course bugs. This is my second round.
