Launching an app is not the end of the project — in many ways, it is just the beginning.

Once an application is available on the App Store or Google Play, a new phase starts: maintenance, optimization and continuous evolution.

Many companies underestimate this stage when calculating the real cost of an app. However, ongoing maintenance is essential to keep the application stable, secure, compatible with new devices and capable of scaling as the business grows.

The cost of maintaining an app depends mainly on:

• the complexity of the application,
• the number of active users,
• the infrastructure required,
• external integrations,
• and the level of support needed.

As a general reference:

• Simple app: €300–€1,200 per month
• Medium-complexity app: €1,200–€4,000 per month
• High-traffic or complex app: €4,000–€12,000+ per month

These costs typically include infrastructure, updates, bug fixes, monitoring and technical support.

What ongoing costs does an app have after launch?

Servers and infrastructure

Most mobile apps require backend infrastructure to function properly.

This may include:

• backend servers,
• databases,
• cloud storage,
• notification systems,
• APIs,
• monitoring tools,
• CDN services.

Infrastructure costs depend largely on traffic volume and data usage.

A small application with limited users may have relatively low server costs. However, as the user base grows, the infrastructure must scale to support increased demand.

“Scalability is one of the biggest hidden costs of successful apps.”

Apps experiencing rapid growth often need infrastructure optimization to maintain performance and avoid downtime.

Updates caused by iOS and Android changes

Mobile operating systems constantly evolve.

Every year, Apple and Google release new versions of iOS and Android that may affect how applications behave.

For this reason, apps require continuous updates to:

• maintain compatibility with new devices,
• adapt to operating system changes,
• comply with App Store and Google Play requirements,
• improve security and stability.

If an app is not updated regularly, it may begin to fail, lose compatibility or even become unavailable in app stores.

This is especially important for apps that rely heavily on device hardware, payments, maps or third-party integrations.

Bug fixing and technical support

Once real users begin interacting with an app, unexpected situations inevitably appear.

Even after extensive testing, real-world usage often reveals issues that were impossible to detect during development.

Maintenance usually includes:

• identifying and fixing bugs,
• analyzing incidents reported by users,
• optimizing performance,
• publishing corrective updates,
• solving crashes or compatibility problems.

Technical support is especially important during the first months after launch, when user behavior starts generating valuable insights and feedback.

“The real testing phase of an app often begins after release.”

App monitoring and analytics

Maintaining a healthy app requires constant monitoring.

Monitoring systems help teams detect issues before they affect a large number of users.

These tools typically analyze:

• crashes and unexpected closures,
• loading times,
• backend performance,
• API failures,
• feature usage,
• user behavior patterns.

This data is critical for making informed decisions and continuously improving the product.

Apps that actively monitor user behavior tend to evolve faster and retain users more effectively.

Product improvements and continuous evolution

After launch, many companies discover new opportunities based on how users actually interact with the app.

Some common post-launch improvements include:

• optimizing user flows,
• improving onboarding experiences,
• redesigning certain screens,
• adding small but valuable features,
• improving conversion processes,
• adapting the product to user feedback.

This evolution is usually handled through monthly maintenance plans, agile sprints or dedicated development hours.

“The most successful apps are not static products — they continuously evolve.”

What factors influence app maintenance costs?

Application complexity

The more features an app has, the more effort is required to maintain it.

For example, apps involving:

• payments,
• geolocation,
• real-time systems,
• advanced user management,
• AI integrations,
• external APIs,

usually require significantly more maintenance than simple applications.

Number of users

Growth in users almost always increases maintenance costs.

More users generally mean:

• higher server consumption,
• increased infrastructure requirements,
• more support requests,
• additional monitoring needs,
• higher security demands.

Ironically, successful growth often increases operational complexity.

Integrations with external systems

Apps connected to third-party services frequently require updates whenever those services change.

This commonly affects integrations such as:

• payment gateways,
• CRM or ERP systems,
• analytics platforms,
• marketing tools,
• external APIs.

Even a small external update can force technical changes inside the app.

What happens if an app is not maintained?

Compatibility problems

Operating systems, libraries and mobile devices constantly evolve.

Without updates, apps may begin experiencing:

• crashes,
• broken features,
• security vulnerabilities,
• compatibility issues.

Poor user experience

Unresolved bugs and performance problems directly impact user satisfaction.

This often results in:

• negative app store reviews,
• lower retention rates,
• user abandonment,
• reduced revenue.

Users today expect fast, stable and continuously improving digital products.

Higher long-term costs

When an app goes too long without maintenance, technical debt increases significantly.

In some cases, companies are eventually forced to rebuild large parts of the application simply to modernize outdated architecture.

Continuous maintenance is almost always more cost-effective than allowing the product to deteriorate over time.

“Neglecting maintenance rarely saves money — it usually postpones a much bigger expense.”
