Mobile App Modernization and Loyalty Solutions

The Story

In April 2025, the client engaged FiftyFive Technologies to stabilize and enhance their existing React Native app. A dedicated four-engineer team was deployed to address outdated infrastructure, failed builds, and missing features. The engagement covered SDK migrations, Firebase reconfiguration, and development of new digital services. FiftyFive applied its expertise in custom software development, UI/UX, DevOps, and QA to deliver a scalable, future-ready platform.

Challenges

• 1. Outdated Expo SDK (v48) and multiple breaking migrations

• 2. Firebase conflicts causing iOS and Android build failures

• 3. No loyalty and rewards system for customer retention

• 4. Poor caching and image handling leading to long load times

• 5. Build instabilities including EAS failures and manifest crashes

• 6. Limited authentication and weak user management flows

The Solution

• 1. Migrated Expo SDK from v48 to v53, resolving 15+ build issues.

• 2. Modularized Firebase services; integrated native iOS and Android push notifications.

• 3. Delivered loyalty and rewards program with digital card and campaign banners.

• 4. Built coworking booking system, secure authentication, and enhanced order flow.

• 5. Redesigned home UI with carousels, subscriptions, shimmer effects, and faster image caching.

• 6. Implemented store locator with clustering using Maps API.

• 7. Applied Jest testing, EAS CI/CD, and Mixpanel analytics for stability and tracking.

• 8. Adopted React Native 0.79.5 with TanStack Query v4, GraphQL/REST integration.

The Outcome

The modernized application achieved a 60% faster load time, zero crash reports, and 100% reliable push notifications. The loyalty and rewards program boosted repeat visits, while coworking bookings generated a new revenue stream. Continuous multi-platform releases across five SDK upgrades ensured stability and future scalability. By combining technical modernization with feature expansion, FiftyFive enabled the client to increase customer loyalty, unlock new business growth opportunities, and strengthen its digital market presence.
