Project Overview
Apex Travel is a global booking platform. The client required a responsive, cross-platform mobile assistant matching their visual website design, allowing users to book tickets, review flight status calendars, and receive notifications about gate updates.
The Challenge
Because the launch budget was highly constrained, building native Swift and Kotlin applications separately was not financially viable. The team needed to build a single codebase targeting both stores that retains smooth 60 FPS visual transition speeds and features dynamic offline sync.
Our Solution
We engineered the mobile application on the Flutter cross-platform engine. Flutter compiles code directly to native ARM machine instructions, avoiding JavaScript bridges and maintaining smooth frame rates during scrolling. We integrated Firebase Firestore for real-time ticket alerts and local SQLite databases to store flight details offline.
By using Flutter, we shared 93% of code blocks across iOS and Android, slicing the development schedule by 45% and matching the client's budget goals perfectly.
Key Deliverables & Results
- Code Sharing Rate: Shared 93% of code across store fronts.
- Development Savings: Slashed overall engineering costs by 45%.
- Offline Usability: Cached flight itineraries load instantly without internet.
- Notification Speed: Real-time flight notifications delivered in under 2 seconds.
