Should I parse booking confirmation emails automatically?

It is the killer feature and by far the hardest part — it needs email access, parsers per airline and hotel chain, and constant maintenance. Ship manual entry first, confirm people use the app, then add parsing for the two or three sources your users actually book through.

How do I handle time zones?

Store every timestamp in UTC with the item’s local time zone attached, and always display the local time at the item’s location. A flight that lands "before" it took off is the classic bug, and it makes an otherwise good app feel broken.

How to Build a Travel Itinerary App with AI (2026)

What a travel itinerary app needs

Trips with dates and destinations
Day-by-day itinerary of timed items
Typed items: flight, stay, activity, reservation, transport
Confirmation numbers and attachments per item
Offline access to the whole trip

The screens

Screen	What it does
Trips	Upcoming and past trips with countdowns
Trip Detail	Day tabs with a timeline of items
Add Item	Type picker, time, location, confirmation number, notes
Item Detail	Full booking details, map link, attachment
Settings	Offline sync status, sharing, time zone handling

The data model

Trip: name, destination, startDate, endDate, coverImage
ItineraryItem: tripId, type, title, startTime, endTime, location, confirmationNumber, notes
Attachment: itemId, uri, kind

The build prompt (copy this)

Paste this into ShipNative and it becomes a working React Native app with these screens, navigable in a live preview, in about two minutes:

“A travel itinerary app. Users create a trip with dates and a destination, then add timed items typed as flight, stay, activity, reservation, or transport — each with a location, confirmation number, and notes. Screens: Trips (upcoming and past with countdowns), Trip Detail (day tabs with a timeline), Add Item, Item Detail (booking details plus a map link), Settings. Everything must work offline once the trip is loaded. Free tier covers one active trip.”

Then iterate with small, screen-specific prompts (“make the primary button bigger”, “add an empty state”), preview on your own phone, and export the full Expo project whenever you want. The full method: how to build an app with AI.

How it makes money

Subscription ($4–8/mo) or per-trip unlock, gated on multiple active trips, shared trips with travel companions, and attachment storage. Seasonal usage is the honest risk — most users pay for one trip and cancel, so per-trip pricing often nets more than a monthly plan.

Implementation and the revenue math for every model: how to make money from an app. When you’re ready to ship: App Store and Google Play publishing guides.
