Koloroo today announced the release of the first widgets that run on any iPod with a color screen. TipKalc is an easy-to-use tip calculator with instant check-splitter. "Just spin your iPod's Click Wheel until your bill amount is displayed in the center of the screen. Everything else is automatically calculated for you. It calculates recommended 15% and 20% tip amounts, grand totals, and even splits the check up to five ways." KolorWheel is a color utility that provides scientifically formulated color schemes to match a web page, home decor, shirt or outfit, etc. Both widgets can be loaded onto an iPod from either a PC or Mac and are available at an introductory download price of $5 and $8, respectively: "You select a base color by moving your thumb over the iPod Click Wheel. A suggested color scheme is automatically displayed in the four corners. If you prefer to match your base color to a particular object, you hold your iPod next to it. Again, a suggested color scheme will be automatically displayed in the corners."
