Engineering Homework Help

You have a roommate that is interested creating an Android and iOS app.  With good team working ethics, you decide to conduct some research on the latest technology for any software packages or even app services which may be used to create an Android and iOS app. 

After conducting research, share a step-by-step process helping your roommate in getting started with the process of creating both an Android and iOS app based upon suggestions for software packages or services.  In addition, and when recommending software and or app services, take into consideration if vendors offering such software packages or services offer any free learning resources and how helpful these resources may be in helping your roommate.
