Vim Touch is an Android port of Vim  and it works very closely like Vim on desktop computers. There are some additional features and UI layouts that make using Vim on a mobile platform easier to use  with visual buttons and shortcuts to make editing on a touchscreen or small device more usable. Other than that  it's Vim all the way down with the typical features to expect from Vim being included here. Aside from some roughness caused by the UI suited for small devices and the Android system changing the behavior of Vim a bit  Vim Touch is an excellent port of the text editor for editing files with a familiar interface.
