I myself never used this app, but I can tell you ads are very annoying, and waste of time, I understand you need to fund this app, but there are other ways of doing it. Start a premium service, or something on that lines. I don't want to hear any excuses because you can. You just don't want to. Ads can be, and will be removed, or this be flagged, as scam by Google them selfs. So, think about what you are doing to use users, and causing harm to our expensive devices. Thank you have a nice day.
