How to Build a Travel Planner App With AI

Before you open the builder, define the smallest useful version of the app. For a travel itinerary planner, that usually means helping a user create, view, and adjust a trip without getting buried in edge cases.

Write down three things:

• Users: solo travellers, families, travel agents, or internal team use
• Core jobs: create an itinerary, browse daily plans, save notes, estimate budget, share trip details
• Data: destinations, dates, daily activities, transport, hotel info, notes, budget items

A sensible first version often includes:

• Home screen with a clear trip setup flow
• Trip creation form
• Itinerary screen grouped by day
• Activity cards with time, location, notes, and cost
• Simple edit flow for moving or changing items

Leave out anything you do not need on day one, such as social features, maps, offline sync, or complex recommendation logic. If you want users to save trips across devices, plan for sign-in and a database. If you want to charge for premium itineraries or trip planning services, plan for Stripe. Otherwise, keep the first version local and simple.

Moremade works best when you describe the product in plain language with enough detail to constrain the first build. Be specific about screens, fields, and behaviour. Mention whether you want a website in React + Tailwind or a mobile app in React Native with Expo.

Here is a good example for a first pass:

Build a mobile app in React Native (Expo) for a travel itinerary planner called TripMap. The app should let a user create a trip with destination, start date, end date, travellers, budget, and notes. Show an itinerary screen grouped by day, with activity cards for time, title, location, notes, and estimated cost. Include a home screen, create trip screen, itinerary detail screen, and edit activity screen. Use a clean, simple interface with clear spacing and large tap targets. Seed the app with example trips so the preview is usable immediately.

This is enough to generate a useful draft without over-specifying every pixel. If you prefer a web app, ask for a website instead. Moremade will generate real source code and show a live preview you can inspect and change by chat.

The first draft will usually expose missing requirements. Review the preview as if you were a real user planning an actual trip.

Check these points:

• Can a new user understand what to do first
• Are the trip fields enough to create a realistic itinerary
• Is the day-by-day layout easy to scan
• Are editing actions obvious
• Does the sample data make sense

Then refine with short, concrete follow-up prompts. For example:

• "Add a day summary at the top of each itinerary day with total estimated spend and number of activities."
• "Make it possible to drag or move an activity to a different day and reorder items within a day."
• "On the create trip screen, add trip pace options: relaxed, balanced, packed. Use that value in the example itinerary text."

Good follow-up prompts focus on one change at a time. If something is visually wrong, use Moremade's visual inspector to point at the element and change it. If you need exact code-level control, use the code view.

Not every itinerary planner needs backend features on day one. A demo or internal prototype may only need seeded data and local state. Add infrastructure when a user need depends on it.

Use Supabase if you need:

• User sign-in
• Saved trips across sessions or devices
• Shared trip editing
• File storage for documents or images

A practical prompt would be:

• "Connect Supabase for email sign-in and store trips, itinerary days, and activities per user. Add a saved trips list on the home screen."

Use Stripe if you need:

• Paid trip templates
• A premium planning service
• Checkout for one-off itinerary purchases

A practical prompt would be:

• "Add a Stripe checkout flow for a paid itinerary review service. Use prices I set and show a purchase button on the trip summary screen."

If you are still validating the idea, skip both. A smaller app is easier to test and improve.

Travel tools often look fine in a desktop preview but break down in real use. Test the app on a phone-sized viewport, and if you are building a mobile app, pay close attention to screen length, touch targets, and form entry.

Run through a few realistic scenarios:

• Create a 3-day city break
• Create a 14-day multi-stop holiday
• Edit one activity and move another to a different day
• Add long notes and unusual place names
• Try a very small budget and a very large budget

Look for common weak spots:

• Overcrowded itinerary cards
• Date fields that are hard to edit
• Buttons too close together
• Important information below the fold
• Empty states that do not explain the next action

If you find a problem, ask for a direct fix. Example: "Reduce the visual weight of activity cards, make the day header sticky, and keep the add activity button visible near the bottom on long itineraries."

Moremade's version history helps here. If an edit makes the app worse, you can go back.

Once the basic flow works, publish a shareable version. Moremade can publish in one click to a free yourname.moremade.ai subdomain. If you want a custom domain, that is available on paid plans, and domains can also be bought inside Moremade.

Before publishing, check:

• App name and labels
• Placeholder and sample data
• Any pricing text if Stripe is enabled
• Sign-in flow if Supabase is enabled
• Basic legal pages if the app is public

You can export the full source code as a ZIP at any time or push it to GitHub. For websites, the output is React + Tailwind. For mobile apps, it is React Native with Expo. That matters if you want to continue development outside the builder later. There is no lock-in.

Most first versions fail for product reasons, not tooling reasons. Watch for these mistakes:

• Too many features too early: start with trip creation and a readable itinerary, not maps, chat, and recommendations all at once.
• Weak sample data: if the preview is empty or unrealistic, it is hard to judge the design.
• No clear editing flow: itinerary apps live or die on changing plans quickly.
• Backend too early: do not add sign-in or payments until there is a reason.
• Desktop-first layout: travellers usually check plans on a phone.
• Vague prompts: "make it better" is less useful than naming the exact screen, component, and change.

A good rule is to get one complete user journey working first: create trip, view itinerary, edit an activity, publish a usable version. Then expand.
