App store

Hi
Do any of you know an engineering app for iPad or iPhone ????

Theo

Type engineer into the search bar of the app store, you should get a tonne of decent results, too many for me to mention.

Electoolkit is quite handy for working out current draws for motors on variable voltages etc, also comes with a resistor colour identification chart which is handy amongst other features.

Thanks for thos ideas
I will try with a cad (again!)as to place stuff in my robot and other things
