How to build a quiz app with AI

Before you write a prompt, define the smallest version worth building.

For most quiz apps, that means:

• a home screen that explains the quiz
• a question screen with answer choices
• a results screen with score and feedback
• a restart button

Then decide a few basics:

• Platform: website in React + Tailwind, or mobile app in React Native with Expo
• Question type: multiple choice is the easiest place to start
• Scoring: one point per correct answer, negative marking, or weighted scores
• Content source: hardcoded sample questions first, or stored in a database later
• User accounts: only needed if you want saved progress, history, or user-specific results
• Payments: only needed if access to quizzes, packs, or premium features is paid

Keep version one narrow. A timed exam app with accounts, leaderboards, payments, analytics, and AI-generated questions is really several projects. Start with a quiz that can be completed end to end.

In Moremade, you describe the app in plain language and the AI agent writes the source code. You then get a live preview and can keep changing the project by chat.

Your first prompt should cover:

• the platform
• the screens
• the question format
• how scoring works
• the visual style
• whether to use sample data

A good first prompt is specific enough to avoid guesswork, but not so detailed that you spend longer prompting than building.

Build a mobile quiz app in React Native with Expo for general knowledge practice. Include a home screen, a quiz screen, and a results screen. Use 10 multiple-choice questions with four answers each and show one question at a time. Keep score by adding 1 point for each correct answer. After the last question, show the total score, the correct answers, and a button to restart the quiz. Use simple clean styling, large tap targets, and sample question data hardcoded in the app.

If you want a website instead, say so directly. Moremade generates websites as React + Tailwind code and mobile apps as React Native (Expo).

After the first build, review the live preview like a tester, not like a spectator. Tap through the full flow. Check whether the logic is right before you spend time on styling.

Look for issues such as:

• score not updating correctly
• answer state not resetting between questions
• buttons too small on mobile
• no indication of progress
• cluttered results screen

Then make small, targeted requests. Three useful examples:

• "Add a progress indicator that shows question number out of 10 at the top of the quiz screen."
• "After the user selects an answer, highlight the selected option and disable the other options until they tap Next."
• "Update the results screen to show each question, the user's answer, the correct answer, and whether it was correct."

This is usually faster than rewriting the whole prompt. Moremade also includes a visual inspector, so you can point at an element and change it, plus a code view if you want to inspect or edit the generated code more directly.

If the AI overbuilds, simplify. Ask it to remove extras like animations, categories, or account screens you did not ask for.

A basic quiz app does not need a backend. Hardcoded sample questions are enough for a first working version.

Add Supabase only if you need things like:

• storing question sets in a database
• user sign-in
• saving scores or quiz history
• uploading assets or files

In Moremade, Supabase can handle database, sign-in, and file storage. A practical next step might be:

• create a quizzes table
• create a questions table linked to a quiz
• create a results table linked to a user

Then prompt for the change in plain language, for example: "Connect this app to Supabase. Store quizzes and questions in the database, add email sign-in, and save each completed score to a results table."

Add Stripe only if the product actually charges for access, such as premium quiz packs or paid certifications. Moremade includes a Stripe connector for checkout with prices you set. If your app is free, skip payments until later. Early versions are easier to validate when there are fewer moving parts.

Even if you are building a website, test it on a phone-sized screen. Quiz products are often used on mobile, and small interaction problems show up quickly.

Check these points:

• text is readable without zooming
• answer buttons are easy to tap
• the next action is obvious
• long questions do not break the layout
• results screens handle low and high scores cleanly
• restarting the quiz fully resets state

Also test awkward content:

• very short questions
• very long answers
• all answers wrong
• all answers right
• empty or missing question data if using a database

If something fails, ask for a precise fix. For example: "On small screens, make answer cards full width and keep the Next button pinned near the bottom with safe spacing."

Version history is useful here. If a change makes the app worse, you can go back rather than trying to undo everything by prompt.

Once the core flow works, publish it. Moremade can publish in one click to a free yourname.moremade.ai subdomain. That is enough for internal review, user testing, or sharing a prototype.

If you are on a paid plan, you can connect a custom domain. Domains can also be bought inside Moremade.

Before publishing, do a short release check:

• title and intro text match the quiz topic
• scoring is correct
• buttons and links work
• no placeholder copy remains
• any sign-in or payment flow works if included

You can export the full source code as a ZIP at any time or push it to GitHub. That matters if you want to keep developing outside the platform later, review the code with your team, or hand the project to another developer.

A few patterns cause unnecessary rework.

• Starting with too many features. Get one quiz flow working before adding accounts, subscriptions, or analytics.
• Prompting vaguely. "Make me a quiz app" leaves too much open. State screens, scoring, and platform.
• Changing everything at once. Small follow-up prompts are easier to control and test.
• Adding a database too early. Static sample questions are usually enough for version one.
• Ignoring mobile layout. Quiz interfaces are interaction-heavy and small screens expose weak UI quickly.
• Not checking edge cases. End-of-quiz logic, restart behavior, and long answer text often break first.
• Treating the preview as finished. The first generation is a draft. Expect a few rounds of refinement.

A good rule is to aim for a complete but simple loop: start quiz, answer questions, see score, restart, publish. Once that works, add persistence, sign-in, or paid access only if there is a real need.
