FEG current calculator for iPhone 5S.
Suppose it will work on other iPhone versions and iPad as well.
This application is made for all you real lazy TEM engineers.
It will save you only a minute.
But if you are lazy enough, pay up and I get myself a free cup of coffee.
Please be aware this app does not do more for you than calculate the hexadecimal number if you choose datasheet current with the slidebar.
