App Maintenance & Support – We Keep Your App Current and Performant

Why Professional App Maintenance?

After launch comes maintenance. Software is never "finished" – it must be continuously maintained to remain secure, performant and up-to-date.

What Happens Without Maintenance?

• Security Risks: Unpatched security vulnerabilities in dependencies become gateways for attacks
• Compatibility Issues: New iOS/Android versions can break your app
• Performance Degradation: Your app becomes slower with growing data
• Poor User Experience: Bugs and crashes lead to negative reviews
• Technical Debt: The longer you wait, the more expensive updates become

What Does Professional Maintenance Include?

Our Maintenance Services

Security Updates & Dependency Management

Software dependencies (libraries, frameworks, APIs) change constantly. Regular updates are essential for security and stability.

What We Do:

• Automated Dependency Scanning: Daily checks for known security vulnerabilities (GitHub Dependabot, Snyk)
• Security Patches: Immediate updates for critical security issues
• Major Version Updates: Planned updates to new framework versions (e.g. Flutter 3.x → 4.x)
• Breaking Change Management: Testing and adaptation for incompatible updates
• Rollback Strategy: Safe rollback option in case of problems

OS Compatibility & App Store Updates

Apple and Google release new iOS/Android versions annually. Your app must remain compatible.

What We Do:

• Beta Testing: We test your app on iOS/Android beta versions before release
• Compatibility Fixes: Adjustments for new OS features and deprecated APIs
• App Store Compliance: Adjustments to new App Store guidelines
• New Device Support: Optimization for new iPhone/iPad/Android devices
• Permissions Updates: Adaptation to new privacy requirements (iOS App Tracking Transparency, Android 14+)

Bug Fixing & Incident Response

Bugs happen. What matters is how quickly they are fixed.

Our Bug Fix Process:

• Error Monitoring: Automatic notification on crashes (Sentry, Crashlytics)
• Priority Classification: Critical, High, Medium, Low based on impact
• Fast Response: Critical bugs within 24h, high priority within 48h
• Root Cause Analysis: We don't just fix symptoms, we identify the root cause
• Regression Testing: Comprehensive tests to ensure the fix doesn't cause new problems
• Hotfix Deployment: Fast releases for critical fixes

Performance Optimization

As user numbers and data volumes grow, your app needs to be optimized.

Performance Metrics We Monitor:

• App Launch Time: Time to first interaction
• Screen Rendering: FPS (Frames per Second), janky frames
• API Response Times: Backend performance, database queries
• Memory Usage: Identify and fix memory leaks
• Battery Consumption: Energy efficiency (especially important for mobile)
• Network Usage: Optimize data consumption

Optimization Measures:

• Database query optimization (indices, solving N+1 problem)
• Image compression & lazy loading
• Code splitting & bundle size reduction
• Caching strategies (see Backend Services)
• CDN integration for static assets (see Cloud Services)

Feature Enhancements & Improvements

Based on user feedback and analytics, we continuously develop new features.

• User Feedback Analysis: We analyze App Store reviews and user support tickets
• Analytics-Based Optimizations: A/B testing, conversion optimization
• New Features: Development of new functionalities based on business goals
• UI/UX Improvements: Continuous improvement of user experience

Monitoring & Proactive Surveillance

We don't wait for users to report problems. We monitor your app 24/7.

Application Performance Monitoring (APM)

• Crash Reporting: Sentry or Firebase Crashlytics – immediate notification on crashes
• Error Tracking: Monitor non-fatal errors and warnings
• Performance Monitoring: Real User Monitoring (RUM) for real performance data
• User Session Recording: Understand where users have problems (optional, GDPR-compliant)

Backend & Infrastructure Monitoring

• Uptime Monitoring: 24/7 checks that your API is reachable
• Response Time Tracking: Alerts on slowdowns
• Database Performance: Query performance, connection pool monitoring
• Server Resources: CPU, memory, disk usage
• Security Monitoring: Unusual activity detection, failed login attempts

Alert Channels & Response

• Email Alerts: For high/critical issues
• Slack Integration: Team notifications
• SMS/Call: For critical production issues (optional, Premium Support)
• Incident Response: Defined processes for fast problem resolution

What Does App Maintenance Cost?

The cost of professional app maintenance depends heavily on your app. A simple MVP app with 100 users needs different support than a business-critical app with 50,000 users.

Factors That Influence Your Maintenance Costs:

• App Complexity & Codebase Quality: Well-structured code is cheaper to maintain
• Number of Integrations: Payment gateways, APIs, third-party services
• Traffic & Infrastructure Scale: 100 vs. 100,000 users = different requirements
• Desired Response Times: Business hours vs. 24/7 on-call
• Compliance Requirements: GDPR, HIPAA, PCI-DSS increase effort
• Technology Stack: Modern stacks (Flutter, React) vs. legacy (Ionic 3, Angular 1)

Typical Investment Levels

Hourly Support (Without Retainer)

For occasional maintenance work without monthly commitment, we offer hourly billing:

• Hourly Rate: €120 - €150/hour
• Ideal For: Apps with very low maintenance needs or project-based fixes
• Note: No guaranteed response times, no proactive monitoring

Maintenance vs. Rebuild: When Is What Worth It?

Sometimes it's cheaper to rebuild an app than to maintain old technology. We advise you honestly.

Maintenance Is Worth It When:

• The app is based on modern technologies (Flutter, React Native, current backend)
• The code is well-structured and maintainable
• Only minor adjustments are needed
• The core functionality runs stable

Rebuild May Make More Sense When:

• The app runs on outdated technology (e.g. Ionic 3, Angular 1, old React Native version)
• The code is barely maintainable (technical debt too high)
• Major features are missing that require fundamental architecture changes
• Ongoing maintenance costs > 50% of rebuild costs

We analyze your app for free and give you an honest assessment of whether maintenance or rebuild makes more economic sense.

Transition & Onboarding

You had your app developed by another agency and want to switch to us? No problem.

Our Onboarding Process:

1. Code Review (1 Week): We analyze your code, architecture, dependencies
2. Documentation Review: Review existing documentation or create new
3. Access Setup: Git access, App Store / Play Console, cloud provider, APIs
4. Monitoring Setup: Set up error tracking, performance monitoring
5. Knowledge Transfer: Call with previous team (if possible)
6. Handover Report: Detailed report on status, recommendations, priorities

Onboarding Costs: €1,500 - €3,000 (depending on complexity), credited to first maintenance invoice

What Our Maintenance Does NOT Include

To clarify expectations, here's what is NOT included in standard support:

• Major Feature Development: Large new features are billed separately (can be part of package, then count against included hours)
• Complete Redesigns: UI/UX redesigns are separate projects
• Marketing & ASO: App Store optimization, marketing are not part of technical maintenance
• Content Management: If your app has a CMS, you manage content yourself (or we offer content services separately)

Why IntegrIT Solutions for App Maintenance?

• We Developed the App: If we built your Mobile App or Backend, we know every code path
• Full-Stack Expertise: We maintain not just the app, but also backend and Cloud Infrastructure
• Proactive Instead of Reactive: We find problems before they affect your users
• Transparent Communication: Regular reports, direct communication, no hidden costs
• Long-term Partnership: We maintain apps for years – some since 2018
