CribSheet keeps all of your equations and formulas in one place, neatly. Keep equations for Physics, Chemistry, BioChemistry, Math...you name it! Create your own classes/categories and store your equations so they are at your fingertips when you need them. Write in your equations - superscripts, subscripts, and all. This app allows for you to describe or reference your formula right on the same screen in which you view it. CribSheet is color enabled. Choose among 64 colors in which to write your information. Monochrome PDAs, while not viewing color, can view their information in 16 shades of gray. It's an awesome application for high school students, college students, or anyone who needs to reference equations or formulas quickly.
