What does the buyer wish to accomplish through this project?:

I need an iOS app prototype that serves as an MVP for a startup. It should serve as a basis for further development by myself.

Project Details & Specifications:

Part 1: I need to build an app for iOS, iPhone5 and above. The app prototype should demonstrate the basic functionality of an app.
It includes a signup page (1) with email and password. Next is a screen (2) to customize one's profile. Next is a selection menu (3) of several categories. Clicking on a category starts a quiz (4) which is timed and stops being shown after 10 seconds. The quiz shows a question on the top, a picture below, and a vertical slider with which a value can be changed. Based on time and accuracy of the real value, you can receive a score. The variables of this question (time needed until response, value estimated) is stored in a database that belongs to that question. Every answer by every user is stored in that database. After going through several questions, the last screen (5) shows the total score.
In total these are five main screens.
There needs to be a possibility to easily design questions that appear in the quiz.
Wireframe of this project exists. UI design exists.
Part 2:
I need an online desktop dashboard to see results of the users' total score.
