The app works and does what it claims by cleaning the speaker. However, the experience is ruined by excessive ads, I had to watch around 6 ads just to use it. There are similar apps that work just as well with fewer ads. Good functionality, but the ad frequency really needs to be reduced.
It took me 4 Ads to get to the option, it only take a few seconds to load in for me but for other people might load in very long time, it just make those annoying noise to clean the phone pitch by pitch and also when you try to quit while cleaning it just begging you to keep cleaning with a cat PNG that are crying for it. And also I dont even know if the ads I saw on YouTube does work.
Lots of ads and not very helpful. I downloaded the app because my phone gets very dusty because of my pellet stove. My parents just had a new one installed, and my phone becomes very dusty. After I downloaded the app I had to wait several minutes just to get to the main menu, as there were several ads. One of them I suspected to be a virus. It didn't clean my phone at all and just made a loud obnoxious noise
