App to replace physical buttons

There's a free app that replaces the functions of the physical buttons of the android system (back, apps open, home), I have an old Android phone that due to heavy use the buttons were somewhat unresponsive, and without them it was almost impossible to use. If you need it its name is Backbutton, and here's the link (it's free and it doesn't need root access)

Wow. I would need to share this with my friend. It's only for android right?

I know that there's for iOS too. Anyways, it's really helpful for those who have their buttons broken already. Gonna recommend it to my friends.

Well, this is good alternative of buttons. If someone having any kind of defects in any of those button, then this is good option to workout with. I didn't know that without rotting also we can having something like this. Thanks for sharing.

That's pretty cool! Similar to assistive touch on the iPhone, useful.

That's cool what a nice new invention! Seems like a good idea for those who want the App to replace those buttons.
