What is the best (easiest to use) Financial Calculator available ??? I would prefer something like the CALCULATED INDUSTRIES model as apposed to the HP or TI. (Calculated Industries was MUCH more intuitive and easier to learn/use.) A SCIENTIFIC calculator would also be nice, but they don't necessarly have to be the same; (but idealy they would be in "one" calculator albeit with changeable screens. IF the same calculator, even thought the actual buttons would need to be different, at least the same "logic" would be incorporated so the operating methodology would be same/similar). THANK YOU for any help ....

The best known financial calculator is the HP-12c. Just be entering 'HP-12' into the Android Market search yielded many results.. https://market.android.com/search?q=hp-12&so=1&c=apps I personally prefer the RPN notation and have loaded Free42, an HP-42 emulator that I also use on Windows and Linux. I used to use it on PalmOS as well. Free42, an HP-42S calculator simulator

Can I bump this by saying I am looking for a similar thing. Migrating from Palm there is an old program called Parens which Palm themselves later emulated on the Treo 650 calculator. The Top 2 rows of keys change function depending on the mode which included the functions below. Still the most comprehensive and easiset to use that I have seen. Has anyone seen these and know of similar approach for android? Parens included; Math - Log, natural log, powers etc Trig + hyperbolic Trig functions Time Value of Money, amortisation, % & (Delta%?) reverse calcuations which I have used countless times. Logic Stats Time Calculations - eg. how many days b/w now and 1st july next year very powerful Engineering Unit conversions I see SmudgeBoss posted the same question at the start of the year. See the documentation for Parens below - it would be a great project for a programmer to pick up - anyone??? Rick Huebner are you still out there?? Parens User's Manual DaveSyd

I am also seeking a parens calculator and nothing comes about. I am sure there's enough of us that would pay something for it.

You could try this one. Wow is this an old thread. https://play.google.com/store/apps/details?id=com.financial.calculator&hl=en
