Fixed my right click problems

I couldn’t right click on safari in iOS. With this app I now can. It’s a life saver. And it’s free unlike those right click apps sold on the App Store

App is terrible

Arguably such a garbage app that deserves no wasted time.
Deserves to go into a dumpster. Thats how garbage this app is.
Just stop making garbage apps like this.
