Amazing! Saved my iPhone 13 Pro Max!

I tried to balance my iPhone 13 Pro Max on the top of the shower, which is about 6 and a half feet high. It fell flat on its back and slid into the shower stream. The audio immediately sounded distorted to the point that I thought the impact had knocked the speaker connection loose or busted the speaker! I turned the phone off and wrapped the iPhone in a towel while I finished my shower. When I got out, I made sure the phone was dry and decided to turn it back on and test the speakers. Still distorted. After a quick google search, I found the Clear Wave app and voilà! You just press the test button, place your phone face down, and plug your ears (if you are sensitive to certain tones or pitches). Cherry on top: After it runs through the cycle of water and debris clearing tones, you get to test your sound with a pretty fire beat! I was so satisfied with the results that I actually rated and reviewed an app like a real grown up! Thank you, Clear Wave. You did what my mom has been trying to do for 35 years. Now if you’ll excuse me, I need to file my taxes or something

saved my phone after i dropped it in my pool

although my phone is waterproof, this app helped me so much. My audio was broken and I couldn't hear anything either it was very muffled or I couldn't hear anything whatsoever. Once I downloaded this app I did not expect it to work as well as a dead I could hear what I was playing and it wasn't muffled and my phone didn't feel like it was filled with water and it also stopped giving me the notification that says your phone is full of water. This app is so helpful and I am so happy about my phone not being water damaged. Thank you for this wonderful app and I hope that you could create more like this or create more apps because I will always be there to download it. Thank you <3

Great other than ads

This was so good. I put my right AirPod in the pocket of my jeans and forgot so I put them in the washing machine. Bout half way through the wash I realized I had left it in there so I quickly took it out and went to this app that I had gotten just a couple hours earlier today… I had to put my finger around the AirPod to act like it was in my ear to get the sound to work but after that I turned the volume to 100% and watched it do its magic… the ads are kinda annoying but it’s fine since it saved me 250$ 😅… Apple AirPods ain’t waterproof (as they say on their website) so I was so shocked. This worked so good 🙏🏼
