Mobile App Modernization
Expertise
• 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• Outdated UI/UX that doesn't meet modern standards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
• 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
• 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
• 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%
• 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
• 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
• 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
• Compliance Review: Ensure adherence to latest store guidelines
• Pre-submission Testing: Comprehensive testing on multiple devices
