The new programs are TipKalc – an easy-to-use tip calculator with instant check-splitter, and KolorWheel – a color utility that provides scientifically formulated color schemes.

To use TipKalc, iPod owners spin their iPod’s click wheel until their bill amount is displayed in the center of the screen. Everything else is automatically calculated as the program calculates recommended 15% and 20% tip amounts, grand totals, and even splits the check up to five ways.

KolorWheel can be used to match colors for a web page, home decor, shirt or outfit, among other things. Koloroo claims that using this widget is just as easy as using TipKalc. Users select a base color by moving their thumb over the iPod click wheel. A suggested color scheme is automatically displayed in the four corners.

Both widgets can be loaded onto an iPod from either a PC or Mac and are available at an introductory download price of $4.99 and $7.99, respectively, from Koloroo’s website.
