Ratings and reviews

Doesn't "dowhat it says on the tin": refuses to amplify phone media sound. Pressing "Phone media" crashes the app EVERY TIME (yet the mic media works). I was hopeful that the recent update would've cured this, but no. I have a new pair of fancy headphones, but despite all the bells and whistles, the volume is just too low, even at 100%. Many roads point to this app as a solution, but wow - abject failure. I'm on a Pixel 6 Pro running the latest version of Android.

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.

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
