4 stars: works! but it doesn't work if you close the app. It would be nice if it works with the app closed
5 stars: This app is always on. Because of it, I can now hear my phone!! For the folks with hearing problems, this is an answer to prayer. 8/30/19 I'm still so happy with this app. Please try it if you have any hearing problems. I continue to leave it on all the time. To the maker of this app, I can't thank and praise you enough!!
3 stars: Works well, but when changing booster level up or down, you hear some noise like from bad radio signal. When you leave booster level in same position there is no noise. Also, way too many ads. And I dont know if the problem is from app or my earbuds, but for some songs boosting volume decreases audio quality.
5 stars: You must experiment to learn how to operate this volume control. After a few weeks I eventually learned because there are no instructions really you have to say hit and miss but now I think it's the greatest thing you must try this!!!🤗😌👍❤️
5 stars: i just got it, haven't had the chance to hear any differences. 1 call i received sounded louder, when it rang. I'm looking for hearing someones voice, if louder than it was. Thank you.
