2. Building Steps
2.1. Research & Analytics
The research and analytics phase is the foundation that determines app success. In the context of 2025, market research needs to focus on new technology trends like AI, Machine Learning, and 5G. Startups need to deeply analyze user behavior, study competitors, and clearly identify their product’s unique value proposition.
Research should include analyzing suitable platforms (iOS/Android), assessing technical capabilities, and planning optimization for search engines (SEO), as well as Generative Engine Optimization – an emerging trend in 2025.
2.2. Plan
The planning phase in 2025 needs to integrate advanced technology factors. Planning must consider AI integration, compatibility with foldable devices, and 5G network optimization.
Startups need to create detailed development roadmaps, define an MVP (Minimum Viable Product), and prepare for future scaling. Plans should also include security strategies, as cyberattacks on mobile apps have increased to 83% compared to 65% the previous year.
2.3. Develop & Test
The development and testing phase accounts for 40-55% of the app development budget. In 2025, development needs to focus on integrating new technologies like generative AI, Extended Reality (XR), and blockchain technology.
The testing process needs special attention to security, multi-device compatibility, and performance on 5G networks. Testing should include both automated and manual testing to ensure the highest quality.
2.4. Launch
The launch phase in 2025 requires a comprehensive marketing strategy, leveraging social media platforms and influencer marketing. App Store Optimization (ASO) is also extremely important to ensure discoverability on app stores.
3. Must-have Features
3.1. “How-to” Screens
In the context of users increasingly expecting intuitive and easy-to-use experiences, designing instructional screens becomes more important than ever. “How-to” screens need to be designed according to modern UX/UI standards, integrating interactive elements and animations to increase engagement.
3.2. Chat Support
Integrating AI-powered chatbots has become the dominant trend in 2025. Successful apps like WhatsApp and banking apps all use AI chatbots to provide 24/7 customer service. This not only reduces operational costs but also enhances user experience.
3.3. Search Options
Search functionality needs to be optimized with AI and Machine Learning technology to provide accurate and personalized results. Integrating voice search and visual search is also becoming the new standard.
3.4. Push Notifications
Smart push notification systems use AI to analyze user behavior and send appropriate notifications at optimal times, increasing engagement and retention rates.
3.5. Multi-Device Synchronization
2025 witnesses the strong development of connected device ecosystems. Apps need seamless synchronization capabilities between smartphones, tablets, smartwatches, and other IoT devices.
3.6. Scalable Text
Accessibility features are increasingly emphasized, supporting users with special visual needs through scalable text features and other accessibility options.
3.7. Data Caching
With the development of cloud computing and edge computing, optimizing data caching becomes important to ensure app performance and save bandwidth.

- Regular security audits and penetration testing
5. Time & Cost
Understanding the time and cost requirements for mobile app development is crucial for startup planning and budgeting. The development timeline and investment needed vary significantly based on app complexity, features, and target platforms. In 2025, factors like AI integration, 5G optimization, and enhanced security measures have influenced both development duration and costs.
Simple apps with basic functionality typically require 3-6 months of development time and represent the most cost-effective entry point for startups with limited budgets. These applications focus on core features with standard UI/UX designs and minimal backend integration. Medium complexity apps, requiring 6-12 months of development, incorporate advanced features, custom designs, and AI/ML integration that significantly enhance user experience but require substantial investment in both time and resources.
Complex enterprise-level applications demand 12+ months of development and represent the highest tier of mobile app investment. These sophisticated solutions include advanced AI/ML capabilities, multiple platform integration, extensive security measures, and comprehensive testing protocols. The extended development timeline reflects the intricate architecture and rigorous quality assurance required for enterprise-grade applications.
Budget allocation across all app categories typically follows industry standards, with discovery and planning consuming 10-15% of the total budget, design accounting for 15-20%, development representing the largest portion at 40-55%, testing requiring 15-20%, and deployment with marketing taking the remaining 10-15%. This distribution ensures balanced resource allocation across all critical development phases while maintaining quality standards and market readiness.
