Introducing ResistanceCalc+, The BEST graphical resistance calculator built for iPhone, iPad, and iPod Touch. If you have ever worked with resistors, whether you are a senior electrical engineer or a high school physics student, you know how tiring and tedious it is to manually calculate resistances. Now you can calculate resistances with one easy click, with a beautiful and intuitive interface! Simply choose the colors of the resistor's bands and the resistance is calculated. ResistanceCalc+ also includes a reference section for double checking the values, or memorizing the color codes. Once you use ResistanceCalc+, you won't be able to believe you once lived without it!
