There are modern calculators: Mathematica, Matlab, and the most used: Excel

For tasks that need to be done away from a computer sure a calculator is handy but that has rather dwindled down to basic calculations. Schoolwork sure calculators are great but I never needed more than my HP-48 and when I did it was usually an assignment meant more for MATLAB/Mathematica.

Now for your point of building it on top of android, what I want is not another device but I want a new calculator built for android. Everyone has a smartphone these days why should I have to buy a calculator when I have a strong computer in my pocket. We just need an interface for smartphones and the appropriately strong (Programmable) back end.

This looks nice but I don't have an iPhone https://itunes.apple.com/us/app/nd1/id368497993?mt=8
