While finishing up my app I conducted some user testing on two different people who fall into my target audience. Both testers used the app prototype in invision alone and made notes based on their experience. Then I walked through the app with them and we talked about its different features. User testing helped me to refine the features and the design of a the app.
I also conducted an “object analysis” to learn more about what kinds of cleaning products my target audience owns and uses so I could be more aware of what kinds of products they would be using the app for. For this I was “let loose” in the bathroom of one of a member of my target audience who had served as a reference for the persona development. I compiled a list ( and some pictures) of what products they owned and used.
