having to pay wasn’t in the description
my phone wasn’t letting me charge it because I got water stuck in the charging port and I downloaded this app because I heard good stuff about it and it’s trying to make me pay for stuff.

UNBELIEVABLE
Wow!! I fumbled my phone into a 10 foot swimming pool. Recovered 30 seconds later. Speaker sounded horrible, 30 seconds of Clear Wave and water gone!!

PAYWALL
Like all things this app has a subscription service, which makes it less useful than it’s worth. If the app itself was worth money and we could use the app whenever when we bought it, that would’ve been better.

Does What It Says It Does
I honestly thought this app was a gimmick, but it surprised me. My phone wasn’t charging at all, and after I used the frequency feature, it started working immediately. I can’t say for sure whether the frequency actually fixed the issue or if it was just a coincidence, but the timing was impressive enough to make me rethink my first impression.

Bad
One time I was painting and listening to music and then my watercolor water spilled and then I dropped my iPad on the floor and I dry it out with a towel, but I think that there’s still stuff in it and it said that it wouldn’t let me use it unless I pay for it. Like why would I spend my money on that when I have better stuff to spend on?
