Electrodroid:
This is a very well written application which is a great reference for engineers doing hardware design. I almost use it on a daily basis. I won’t go though all the features, because it is feature packed! Check out the description on the developer website for a complete list. From resistor codes to op-amp calculators to common pin-outs to reference tables such as ASCII codes- everything we need, right in our pocket! Brilliant. I highly recommend this application!
