Orfox is one program browsing for Android which is based on the same source code as the Tor browser. However, the Android application also has some additional privacy changes.
Basically, if you want to run Tor on Android, Orfox is probably the best option.
The installer is not too complicated, but it requires more than installing the Orfox app.
You'll also need to install the Orbot app for Android. Without it, you can not use the browser as it will not be able to use it Tor Network. Orbot is what connects to the Tor network and that's why you can't use the browser without it.
Orofox asks you to install Orbot when you run the application for the first time. if you have not already installed the secondary application, use the notification that appears to install it.
Orfox is based on Firefox (as Tor Browser is) and comes with NoScript browser settings plugins and Tor Browser Settings.
The application by default is set to the Tor browser template (where the default security level is low).
