Best Loan Calculator?

[blablum]

I've been looking for a good loan calculator and I found some but none of them seem to combine all features I would like:

Finger friendly
Graphing capability
Choice of term length (monthly, weekly, biweekly,etc)
Allows for inclusion of extra one time payments (beyond the normal ones)
Comparison of different loans

If anyone knows an app that meets these (or most) requirements I would appreciate your input. Thanks.

I am looking for the same thing. Anyone?
