Ratings and reviews

I needed do remove mic permission from Google App, otherwise, this app never works because "the mic is not available". Tryed a little and didn't notice any improvement in the sound. In fact, the environment voices was louder than in the app. Also, there is a big delay, even using device's mic or headphone's mic, thus, it's like listening to a bad eco

App crashes and i get a notification saying "this app stopped working because it had a bug" after using it for only 5-10seconds. On the rare occasion it doesn't crash however, it honestly works great. Having the option to choose whether to boost low or high frequency sounds is an amazing feature and same for the noise reduction. It just needs some bug fixes

Worse than nothing. Even at maximum volume, the mic phone audio is almost silent on my Bluetooth earbuds, and there is a definite delay. I hear the external audio with my ear, then a very faint copy after. I can definitely hear better without an ear bud in my ear, let alone with one repeating poorly out of sync. It appears they have been "working" on these issues since 2019, so I have little hope in this ever working.
