Mobile App Modernization
Expertise

Consider modernization when experiencing:
• Frequent crashes or performance issues affecting user experience
• High maintenance costs and difficulty finding developers
• Outdated UI/UX that doesn't meet modern standards
• Inability to integrate with modern APIs or services
• Security vulnerabilities or compliance issues
• Platform version incompatibility (iOS/Android updates)
• Poor app store ratings due to technical issues
• Limited scalability for growing user base

The key differences are:
• Modernization: Incrementally updates existing code, preserves business logic, maintains data structures, and costs 40-60% less than rebuilding
• Rebuilding: Complete rewrite from scratch, allows for fundamental architecture changes, longer timeline but clean slate
• Our Approach: We analyze your app to recommend the most cost-effective strategy, often combining both approaches for optimal results

Timeline depends on app complexity:
• Simple Apps (5-10 screens): 2-3 months for complete modernization
• Medium Complexity (10-25 screens): 3-6 months with phased releases
• Enterprise Apps (25+ screens): 6-12 months with milestone-based delivery
• Factors affecting timeline: Current code quality, number of integrations, platform requirements, and feature additions
We provide detailed project timelines after initial assessment

Yes, we offer multiple approaches:
• Cross-Platform Migration: Convert to React Native/Flutter for single codebase
• Parallel Modernization: Update both native apps simultaneously
• Progressive Web App: Create unified PWA for all platforms
• Hybrid Approach: Modernize critical features cross-platform while maintaining native elements
This approach can reduce development costs by up to 40% and maintenance by 60%

We ensure minimal user disruption through:
• Phased Rollouts: Gradual feature updates to test and gather feedback
• Data Migration: Seamless transfer of user data and preferences
• Backward Compatibility: Support for older app versions during transition
• A/B Testing: Test new features with select user groups
• Communication Strategy: Keep users informed about improvements
• Fallback Options: Ability to rollback if issues arise

Our technology recommendations based on requirements:
• Cross-Platform: React Native for JavaScript teams, Flutter for performance-critical apps
• Native iOS: Swift/SwiftUI for premium iOS experiences
• Native Android: Kotlin/Jetpack Compose for Android-first apps
• Progressive Web Apps: For broad accessibility and lower costs
• Backend: Cloud services (AWS, Firebase, Azure) for scalability
We select technologies based on your team's expertise, budget, and long-term goals

Our data migration process ensures zero data loss:
• Data Audit: Complete inventory of existing data structures
• Migration Strategy: Custom scripts for data transformation
• Backup Systems: Multiple backups before migration
• Incremental Migration: Phased data transfer with validation
• Testing Protocols: Extensive testing in staging environments
• Rollback Plans: Immediate recovery options if needed
• User Data Integrity: Preservation of user preferences, history, and settings

We ensure smooth app store approval:
• Compliance Review: Ensure adherence to latest store guidelines
• Pre-submission Testing: Comprehensive testing on multiple devices
• Asset Preparation: Updated screenshots, descriptions, and metadata
• Gradual Rollout: Staged release to monitor user feedback
• Response Management: Quick resolution of any store feedback
• Version Management: Maintain older versions during transition
Our team has 95% first-attempt approval rate

Yes, we specialize in complex modernizations:
• API Modernization: Update legacy APIs to RESTful/GraphQL
• Microservices Migration: Break monolithic backends into services
• Database Optimization: Migrate to modern database solutions
• Cloud Migration: Move on-premise systems to cloud
• Integration Updates: Modernize third-party integrations
• Performance Optimization: Improve backend response times
We maintain business continuity throughout the modernization process

Typical ROI metrics from our modernization projects:
• Performance: 50-70% improvement in app load times
• Maintenance Costs: 40-60% reduction in ongoing maintenance
• User Retention: 25-40% increase in user engagement
• Crash Rates: 80-90% reduction in app crashes
• Development Speed: 2x faster feature deployment
• Revenue Impact: 15-30% increase in conversions
• Support Tickets: 50% reduction in user complaints
