Overview

The project in context.

Quizfinity is a mobile learning product that connects onboarding, category selection, timed quizzes and results in one clear progression from starting a session to completing a level.

The challenge

Interactive learning needs a clear sense of progress.

A quiz moves through several states quickly: choosing what to play, understanding the rules, answering under time pressure and reading the result. The experience needed to keep each transition clear without slowing the learner down.

Product experience

A complete quiz journey in a focused mobile flow.

  • Onboarding and access: Introductory screens and email authentication establish a clear entry into the product.
  • Category selection: Topic cards help users choose the kind of quiz they want to take.
  • Timed levels: Difficulty changes the available time while question and answer options remain easy to scan.
  • Results and feedback: Completion states communicate pass or fail and support retrying or progressing to the next level.

Frontend decision

Keep each screen focused on one decision.

The experience separates onboarding, selection, instructions, play and results into distinct stages, giving every screen one primary purpose.

That structure keeps category, level, timing and completion state understandable without adding interface complexity that the quiz does not need.

Reflection
