Congratulations, your app is in the App Store! But the work has not been done for a long time. Continuous maintenance and updates are the basis for long-term success.

> Key Takeaway: Regular app maintenance and updates are not optional but mandatory: new iOS and Android versions require adaptations, security vulnerabilities must be patched promptly, and performance optimizations must be implemented continuously. Without ongoing maintenance, app ratings and downloads decline within months.


Congratulations, your app is in the App Store! But the work has not been done for a long time. Continuous maintenance, regular updates and professional support are the basis for long-term success.

Why is app maintenance necessary?

An app is not static software. It exists in a dynamic environment:

  • New OS versions: Every year, Apple and Google release new versions of iOS and Android.
  • New devices: New smartphones with other screen sizes require adjustments.
  • Securities: Regular security updates are essential.
  • ** Changes to third-party services:** If your app uses external APIs, you need to respond to changes.

Columns of a good maintenance strategy

  • Technical support: A firm contact person for technical problems.
  • Monitoring: Continuous monitoring of app performance and crash reports.
  • Bug fixation: Fast fixation of errors.
  • ** Regular updates:** Scheduled release of updates.

Updates: More than just bug fixes

Regular updates are also an important marketing tool:

  • Feature Updates: Expand the app based on user feedback.
  • Performance improvements: Optimize charging times and battery consumption.
  • UI/UX improvements: Modernize the design.

What does the app maintenance cost?

As a rule of thumb, you can expect annual maintenance costs of about 15-20% of the original development costs. This investment ensures the value of your app.
