An Amazing app my dude

I rarely ever rate apps, but I had jumped into the shower with my iPhone 7 plus since it is advertised as 'water-resistant' — but if It couldn't survive a trip in the shower who know what they mean by resistant— and when I had got out the upper speaker (the one used when calling) was super mumbled so I tried putting it in rice for an hour & nothing, it was still muffled. I then proceeded to blow dry it for 10 minutes and still nothing (also I'm not stupid, I put the blow dryer on cool so it would heat up my device). So I then googled ways to get water out of iPhone 7 speaker and when I read this article on a website I had thought it was some lousy app that just basically makes money from watching the ads. I was desperate and only had 2 options either give the app a try or making the purpose of the phone useless; since apple's 'water-resistant' iPhone 7 warranty doesn't cover water damage. So in less then 2 minutes of me switching the frequencies from high to low, I decided to listen to the same song I had tried to listen too prior to using the app and this time it sounded as if nothing happened to the phones speaker. I honestly don't get the philosophy behind this app, but thanks so much to the person who thought of creating it.

Saved my phone

About a week ago I was hiking in Arizona. My family and I reached the end and just as we turned around to head back it started pouring rain. The hike was about a mile and a half one-way, and I had my phone in my back pocket. After ten minutes or so I remembered I had my phone with me and attempted to keep it shielded from the rain with my hand. We continued to be drenched for another twenty minutes or so. Nonetheless, I played a song when we got back and the speakers sounded pretty muffled. When played at a certain volume, a static sound emitted as well. Naturally I freaked out since iPhones aren’t cheap to replace but I looked on the internet for possible solutions. I came across an article that recommended this app and I had nothing to lose, so I went ahead and downloaded it. Best decision I made that day. The interface was extremely easy to use and after using the recommended 165 Hz frequency for a couple minutes, I played the same song in nervous anticipation. It was like the water damage never happened and the speaker sounded great! Very thankful this was so effective. Highly recommend!

Fixed/safed my Water Damaged iPhone XS earpiece!

This app is amazing. I dropped my iPhone XS in the lake yesterday. It was sitting in about 7 feet deep water for a couple minutes. When I was finally able to fish it out, at first glance everything appeared to work fine. Then I made a call and realized that water had gotten into the earpiece. It was very muffled and I could barely hear anything. I randomly found this app after searching on Google. What I did was select the frequency of 160, turn up the volume on the phone to max, tap start, flip the phone upside down on a paper towel, so that the earpiece was facing the paper towel and after like 20 seconds you could already see water coming out of the earpiece and the bottom speaker soaking up the paper towel. I ran it for like a minute at first. Waited a few seconds and then again for like a minute. Eventually no more water was coming out and the phone was back to normal! Key is to set it at 160khz. This seems to be the ideal frequency for maximum vibration/water disbursements!!

This app literally made my day!
