How to Build a Mobile App With AI

Before you open any AI builder, write down the basics in plain language.

Keep it short:

• who the app is for
• the single main task it helps with
• the 3 to 5 screens it needs first
• what data each screen shows or collects
• whether users need accounts
• whether you need payments

Example for a simple habit tracker:

• users: people tracking daily habits
• main task: mark habits complete each day
• screens: home, habit detail, add habit, profile
• data: habit name, target frequency, completion history
• accounts: yes, if progress should sync across devices
• payments: no, unless you plan a paid tier

This step matters because AI works better with constraints than with broad ideas like "build me a fitness app."

In Moremade, you describe the app in plain language and the AI agent writes the source code. Mobile apps are built as React Native apps using Expo.

Your first prompt should cover:

• the app's purpose
• target users
• required screens
• key actions on each screen
• visual style
• what not to include yet

Keep the first version narrow. Ask for a usable draft, not the finished product.

Build a mobile app for iPhone and Android called Habit Day. It helps users track daily habits. Create four screens: Home, Habit Detail, Add Habit, and Profile. On Home, show today's habits with a clear complete button. Habit Detail should show the habit name, target frequency, notes, and recent completion history. Add Habit should let the user enter a name, choose daily or weekly frequency, and save. Use a clean, simple layout with large tap targets and neutral colours. Do not add payments, social features, or notifications yet.

That level of detail usually produces a better first pass than a one-line request.

After the first build, use the live preview to inspect the app as a user would. Look for missing states, unclear labels, awkward spacing, and navigation problems.

Moremade lets you change the app by chatting, and it also includes a visual inspector and a code view. Use the visual inspector when a specific element is off, such as a button size or padding. Use chat when the change affects behaviour or layout across screens.

Good follow-up prompts are concrete. For example:

• "On the Home screen, move the add habit button to a fixed bottom action button and make completed habits appear below incomplete ones."
• "Add an empty state on Home that explains what to do before any habits exist, with a button that opens Add Habit."
• "Make the Profile screen simpler: remove avatar placeholders, show only name, email, and a sign out button."

Short revision cycles work best. Make one group of related changes, check the preview again, then continue.

A first app draft does not always need a backend. If the app is just a prototype or a local demo, you may be able to validate the flow before adding accounts or payments.

When you do need backend features, Moremade includes built-in connectors for Supabase and Stripe.

Use Supabase when you need:

• user sign-in
• a database for app data
• file storage

Typical cases include task apps with saved progress, marketplaces with user accounts, or internal tools where data must persist.

Use Stripe when you need:

• paid subscriptions
• one-time purchases
• checkout with prices you set

Do not add Stripe unless there is a real payment step in the user journey.

A practical instruction might be:

• "Add Supabase email sign-in and store habits per user so each person sees only their own data."
• "Add a Stripe checkout screen for a premium plan, but keep the free version usable without payment."

Add these pieces after the core screens work. Otherwise you end up debugging product scope and integration details at the same time.

A mobile app that looks fine in a browser-sized frame can still fail on a real device.

Check the basics on both iPhone and Android if possible:

• tap target size
• text wrapping on smaller screens
• keyboard covering form fields
• long lists and scrolling behaviour
• loading and empty states
• navigation back behaviour

Because Moremade builds mobile apps in React Native with Expo, you are working toward a real app codebase rather than a mockup. That makes device testing worth doing early.

As you test, write fixes as specific requests:

• "The save button is hidden when the keyboard opens on Add Habit. Keep the button visible above the keyboard."
• "The Habit Detail screen needs more spacing between the notes field and the completion history list."
• "On Android, make the header title shorter and prevent it from wrapping to two lines."

This is usually where the app starts to feel solid.

When you have a version worth sharing, you can publish from Moremade.

What Moremade offers:

• one-click publishing to a free yourname.moremade.ai subdomain
• custom domain connection on paid plans
• domain purchase inside Moremade
• ZIP export of the full source code at any time
• GitHub push for the source code

For internal review or early feedback, the free subdomain is usually enough. If the app is part of a client project or a public launch, use a paid plan and connect a custom domain.

Version history is available on Standard and Pro plans, which is useful once multiple rounds of changes begin.

Even if you publish from Moremade, you are not stuck there. The source can be exported as a ZIP or pushed to GitHub.

Most problems come from scope and vague instructions, not from the tool itself.

Watch for these mistakes:

• asking for too much in the first prompt
• mixing prototype goals with production requirements
• adding sign-in and payments before the core flow works
• giving design feedback like "make it better" instead of naming the issue
• not testing on a real phone
• forgetting edge cases such as empty lists, bad form input, and slow loading states

A better process is:

1. build the smallest useful version
2. review the preview carefully
3. refine with specific prompts
4. add data or payments only when justified
5. export the code once the direction is stable

That approach keeps the app understandable and reduces rework.
