App development timelines vary widely based on complexity, but here's what a typical 16-week custom app development project looks like from MKG Techsols's experience:

Week 1-2: Discovery & Planning - Gather detailed requirements and business goals - Create user personas and user journey maps - Develop wireframes for key screens - Select technology stack (React Native vs native vs Flutter) - Create detailed project roadmap and timeline - Deliverables: Requirements document, wireframes, tech architecture

Week 3-4: Design - Create high-fidelity UI designs in Figma - Build interactive prototypes - Design system documentation - Developer handoff documentation - Design review and revisions - Deliverables: Complete UI kit, design system, clickable prototype

Week 5-10: Development (Agile Sprints) - Set up development environment and CI/CD pipeline - Build backend APIs and database - Develop frontend UI components - Implement authentication and security - 2-week sprints with weekly demos and client feedback - Deliverables: Working application, API documentation, test coverage

Week 11-12: Integration & Testing - Integrate all components end-to-end - Complete QA and user acceptance testing - Performance optimization - Security and penetration testing - Bug fixes and refinements - Deliverables: Bug-free, optimized app

Week 13-14: Deployment Preparation - Prepare app store submission materials - Create screenshots and app description - Set up analytics and crash reporting - Prepare privacy policy and legal docs - Training for app management - Deliverables: App store assets, documentation

Week 15-16: Launch & Support - Submit to App Store and Google Play - Monitor for review feedback - Launch marketing campaign - Handle initial user issues - Post-launch optimization - Deliverables: Live app in both stores

Post-Launch: Support & Iteration - 90-day post-launch support included - Monthly updates and feature releases - Performance monitoring and optimization

This timeline assumes a moderately complex app with 15-20 core features. Simple MVPs might take 8-10 weeks, while complex enterprise apps can take 6-9 months.
