I absolutely love this app so far. I snorkel often and take my phone in the water with me. When I’m done all I have to do is use this app to clean my speaker and I can hear my phone calls. Before I discovered this app I was worried I had ruined my speaker. Nope! Just needed the vibrations to clean everything out and it’s good to go. Quick and easy.

I thought I would have to spend a lot of money to fix my phone's speaker because the sound was not coming out after a small accident, but thanks to this app, it works perfectly again.

I can’t tell if my speakers are back to how they used to be but they are definitely a lot better than they were! I could see bits of water come out and weirdly felt air. Very interesting how this all works. I did 3 or 4 rounds and I’m pretty happy with the results

This worked alright. It raised my phones’ speaker volume; exactly what it said on the tin. It’s not the most insane improvement ever, but it doesn’t promise to be, and for that reason — five stars.
