Are the following questions appropriate to garner feedback from an early stage prototype? If not, what questions would be more appropriate:
For the individual:
For the business:
The rating scale questions don't seem useful, unless you'll have an opportunity to follow up in more detail. Imagine that that respondents rated the app 1.5/5 on "features." How would you act on that information?
The "With regard to..." questions are very jargony. Imagine how a user would phrase these questions (e.g,. "Do you have suggestions about how to make the app look nicer?", "How could we make the app easier to use?")
A more fundamental issue with those questions is that you're asking the users to do design. Their job is to use the app and tell you what they experienced, not to decide how to act on it. Ask them for specifics about what they enjoyed, what was difficult, and what surprised them. Then use that information to decide how you can make the app a better fit for their needs.
