Designing a Material flat logo for an app

When I have to design a new logo for one of my apps, I try to create something with a background, with a meaning instead of an abstract logo without significant (it’s easier to keep in mind and get used to). I usually get the inspiration from natural objects and then I finish my design using vector graphics in a minimalistic way. If there is a hardware related with control of the app I use it as a base, if not I just create a new object that represent the app’s functionality as easy as possible.
