Today CalcApps released an upgrade to their iPhone and iPad app, Finance.Calc – Loan and Investment Calculator. This latest version includes some design changes and new features, including a bonus calc, Black Scholes option calc, bringing the total number of finance calcs in this app to 6!

What’s more it is still being offered free for a limited period.

The Black Scholes option calc calculates price, implied volatility or implied interest and can handle a range of dividend assumptions. There is full Greek factors output and charts that demonstrate option sensitivity.

Other improved features include better linking between calcs and their pre-saved examples and a new look for lists.

The latest version includes more user friendly lists.
