It’s always been my primary goal to have Plexus running on the mobile handset. The modules that are up and running will currently work under Android using Google’s Scripting Languages for Android (sl4a) application. You’ll need to install that first, then install the Python interpreter. Next, copy the entire Plexus source code tree to the directory /sdcard/sl4a/scripts/v2 on your handset. Navigate to that directory in sl4a, and you should be able to run the applications from your phone! (Or tablet, if you have an Android tablet.)
This is one of the great advantages of coding Plexus in Python – it’s a very portable language.
