Nexbook — Smart Travel Booking Mobile App

The Challenge

Nexbook needed a mobile app that could compete with Booking.com and Expedia on speed and reliability, while adding personalization — saved itineraries, offline access to boarding passes, and price-drop notifications on watched routes — without draining the phone battery or blowing out storage.

Our Solution

We built a React Native app with a GraphQL data layer for fine-grained querying, SQLite offline cache for itineraries and boarding passes, background push notifications for price alerts (Firebase Cloud Messaging), and a personalization engine that ranks recommendations against the user's past bookings — all in a 42MB install size.

Results & Impact

48% of bookings converted from price-alert notifications alone
Offline boarding pass access used by 73% of frequent flyers
App size kept under 45MB with lazy-loaded image assets
4.7 star rating across Google Play and iOS App Store

Frequently Asked Questions

How does Nexbook handle offline access?

Nexbook caches itineraries, boarding passes, and hotel confirmations to a local SQLite store on first sync. Users can view all trip details, QR codes, and check-in info without any network connectivity — critical for airport lounges and international travel where roaming data is unreliable.

Does Nexbook integrate with airline and hotel inventory systems?

Yes. Nexbook aggregates inventory via the Amadeus GDS for flights and via direct hotel chain APIs plus consolidators for accommodations. Booking confirmation runs through the airline's own PNR system so tickets are always verifiable.
