App Maintenance and Support: What happens after launch

> Key Takeaway: After app launch, the most critical phase begins: ongoing maintenance includes OS updates (iOS/Android versions), security patches, performance monitoring, and feature development based on user feedback.

Without continuous maintenance, an app becomes outdated within 12–18 months and loses users.

App Maintenance and Support: Why the work starts right after launch

• *The launch of an app is an exciting milestone, but it is not the end of the project, but the beginning of a new, decisive phase: the app maintenance and support. Many companies underestimate the importance and costs incurred after publication. This article explains why continuous care is vital to the success of your app and what you should budget. **

Why is app maintenance indispensable?

Short: An app is not a static software that is installed once and then runs forever.

An app is not a static software that is installed once and then runs forever. It exists in a dynamic ecosystem that is constantly changing. Without regular maintenance, your app will inevitably lose relevance, have errors and will ultimately be uninstalled by users.

The main reasons for continuous maintenance:

• New OS versions: Every year, Apple (iOS) and Google (Android) publish new versions of their operating systems. Apps must be adapted to ensure compatibility and use new features.

Safety updates: New vulnerabilities are constantly being discovered. Regular updates are essential to protect your app and the data of your users.

• Bugfixing: No software product is error-free. Even after intensive testing, mistakes (bugs) will occur again and again in live operation, which must be fixed.

• Performance optimization: Servers need to be monitored, databases optimized and the charging times of the app are continuously improved.

• Adjusting user feedback: The most valuable suggestions for the further development of your app come from users themselves.

What does everything belong to the app maintenance?

Short: A typical maintenance contract with an app agency includes the following services:

A typical maintenance contract with an app agency includes the following services:

• Technical support: A firm contact for technical problems.

• Monitoring: Monitor server accessibility and app performance.

• ** Regular updates:** Adaptation to new OS versions and security patches.

• Bugfixing: Fixing errors within an agreed reaction time.

• Backups: Regular backup of database and server.

Costs for app maintenance and support

Short: As a rule of thumb, plan for the annual maintenance and support of your app about 15-25% of the original development costs.

As a rule of thumb, plan for the annual maintenance and support of your app about 15-25% of the original development costs. So if the development of your app has cost €100,000, you should expect annual maintenance costs from €15,000 to €25,000.

This budget ensures the smooth operation and maintenance of your investment.
