Latest reviews, Germany App Store.
Das war mal eine so tolle und nützliche App. Die nervige, ständig wiederkehrende Werbung, die sich meistens nicht wegklicken lässt, weil sie nicht lädt und damit auch keinen Schließen-Button zeigt, verhindert inzwischen eine sinnvolle Nutzung. Schade!
Tried using this app for <15 minutes and was served nonstop adult ads and finally a full screen “your device has been infected by visiting adult websites… install our app to clean your phone”. Didn’t even tune properly when it did work!
but the advertising just keeps getting worse and worse - and i’ve used this since 2014.
I like it. Simply works and has lots of simple options.
Very helpful will few ads
I understand the point of ads for a fee app. I just wish they were easier to click out of. The x in the corner is often hidden under other stuff
