That is the main goal to have the base. I don't' want a mobile version to be a substitute for normal desktop usage, but merely just for quick tasks as finding quantiles, eigenvalues, multiplying matrices or whatever when no desktop computer is nearby.
I've found a few other links that seem interesting, so I'll give it a try and inform you if I succeed.
