E.E. Tool Kit app for iPhone and iPad

EE Tool Kit contains circuit solvers, references and tutorials, and example schematics all in one easy to use app. All solutions are found using standard component values (ones you can buy) and optimized to provide the best solution for the standard values that are available in a range of tolerances. Navigation is performed by selecting entries from a table of contents that indexes and categorizes the solvers and references. EE Tool Kit is written by professional circuit designers and hobbyists for circuit designers and hobbyists with a focus on quickly and flexibly providing useful solutions to everyday problems.

Thirty solvers are provided which address the basics (ohms law calculations) through more complex circuits such as active band pass filters and oscillators. Ten references and tutorials are included which provide often used information such as wire gauge tables with ampacity ratings and standard value tables. Twelve sample circuits are provided that cover the basic building blocks you will most likely use in addition to some novel circuits that are not commonly seen but provide useful circuit functions. Both the iPad and desktop versions of EE Tool Kit use the same interface making it easy to move between them.
