To everyone out there with Android based devices.
I downloaded an app a while ago which I find myself using more and more.
It's called elctrodroid, it's an app for electronic techs, installers, designers, computer techs and tinkerers.
It is by far the most valuable app on my phone, I would sacrifice all others for it in a heartbeat, as a matter of fact it's almost worth the price of the phone on its own.
The data is accurate, the layouts are brilliant, the graphics are professional and the updates are frequent.
I've been speaking with the developer and we're hoping to see a pad calculator soon as well as more audio pinouts.
In three subcategories, here is what's on it so far.
