Which agency will take over Maintenance and support an app?

Maintenance and support is ideally carried out by an agency with its own team that is permanently responsible for operations, updates and further development. This includes regular updates, monitoring, backups, security patches, meeting app store requirements, quick bug fixes and a predictable development roadmap. CodeGuides looks after apps and platforms during ongoing operations, with clear contact persons in Germany.

Introduction · When we take over

Typical Entry scenarios

We get in where the fire is and quickly ensure stability. Depending on where you are in your project, we support you and familiarize ourselves with the project and the processes. If you would like to have a platform further developed or continue to support your platform, we are the one long-term partners.

Team change / delivery stoppage

Previous team is gone, velocity is 0. We take over code, repos & deployments and deliver again.

Audit & security gaps

Dependencies, secrets, missing tests. We harden the setup, set up scans & quality gates.

Cost optimization

Cloud costs are getting out of hand. We measure, optimize and create transparency in dashboards.

Scaling needs

More users, more load. We address bottlenecks, caching, DB tuning and observability.

Compliance & SLAs

Reliable response times and documentation. We establish SLOs, on-call plans and reporting.

Feature backlog

Business is waiting for delivery. We bundle roadmap packages and deliver at fixed intervals.

How much does app maintenance cost per month?

Ongoing app maintenance costs consist of: hosting and cloud infrastructure (50 to several hundred euros per month depending on load), costs for App Store accounts (Apple: 99 USD/year, Google Play: 25 USD one-time), as well as an optional maintenance contract for security patches, monitoring and updates. For Flutter apps (iOS + Android from one codebase), the maintenance effort is significantly lower than for two separate native apps because fixes are only developed once.

How much does it cost to maintain an app?

The maintenance costs of an app depend on complexity, user load and update frequency. Typically: 500 to 2,000 euros per month for simple apps with occasional updates, 2,000 to 6,000 euros for more complex apps with regular releases, security monitoring and active backend operation. There are also one-off costs for iOS or Android operating system version changes.

How long does app maintenance take?

App maintenance is not a one-time operation, but a continuous process: iOS and Android release new major versions every year to which apps must be adapted. Individual maintenance tasks such as security patches take hours to a few days. Major adjustments to new OS versions or API changes can take 1 to 4 weeks.

Which agency offers long-term support for platforms?

Many agencies disappear after the launch. Code guides don't. We support platforms and apps after go-live with structured SLAs, dedicated contacts, regular reporting and a clear development roadmap. No ticket system nirvana, just direct communication with the team that built your app. Get in touch and we'll show you what long-term app support looks like with us.

How do you modernize existing software?

Software modernization takes place in structured steps: (1) Technical audit: code quality, architecture, security, CI/CD; (2) stabilization of critical areas; (3) Gradual modernization: refactoring, migration to modern frameworks, improving the deployment pipeline; (4) Ongoing further development on a clean foundation. Complete rewrites rarely make sense; a gradual migration significantly reduces risks.
