Fitted for the big screen and visually adapted, Trivice HD can now also calculate any given triangle on the iPad. The necessary parameters are:

- Three sides or
- Two sides and one angle or
- One side and two angles

The input is done completely without the keypad by using the graphical controllers on the edges and sides. The controller in the middle sets the fraction digits.
The calculation includes all angles and lengths as well as area, height, perimeter and incircle and circumcircle. The result is also displayed graphically.
The last 10 calculations can be recalled from the history. The number of fraction digits for input and result can be defined in the settings. It is also possible to use fractions for the input, for example for inch values.

A detailed manuall can be optained from the website.
