Which agency will take over Maintenance and support an app?
An agency with its own team is best suited to maintenance and support, taking ongoing responsibility 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 supports apps and platforms in production, with dedicated points of contact in Germany.
Scope: This page describes the ongoing operation of a system that is already stable. The first question is whether you need Takeover, testing and stabilization an existing app Take over an app and continue.

FAQ: App and Platform Maintenance
How does the collaboration start?
Non-binding initial consultation, technical audit, quick wins and prioritized to-dos.
App maintenance: How does it work?
We take over operations, monitoring, security, and ongoing development in clear cycles. You get dedicated points of contact, transparent SLAs, and regular reports.
Platform support: What’s included?
Stabilization, monitoring, patch management, backups, and ongoing development. We can also provide on-call support and help with compliance.
App maintenance agency: Can you take over existing systems?
Yes. We onboard your code and infrastructure, stabilize your release process, and get delivery moving again—with an audit, quick wins, and a roadmap.
What SLAs do you offer?
Defined response and resolution times, optional on-call support, and monthly reporting.
Further platform development: How do you plan it?
We prioritize your backlog together, work in regular sprint cycles, and deliver predictably. The goal is measurable progress in stability and cost control.
Are you working with our team?
Yes—closely and transparently, with active knowledge sharing.
How much does app maintenance cost per month?
Ongoing app maintenance costs include hosting and cloud infrastructure ($50 to several hundred euros per month, depending on load), app store account fees (Apple: $99/year; Google Play: $25 one-time), and an optional maintenance contract for security patches, monitoring, and updates. Flutter apps (iOS and Android from one codebase) require significantly less maintenance than two separate native apps because fixes only need to be developed once.
How much does app maintenance cost?
App maintenance costs depend on complexity, user load, and update frequency. Typical costs are $500 to $2,000 per month for simple apps with occasional updates, and $2,000 to $6,000 for more complex apps with regular releases, security monitoring, and active backend operations. Changes required for new iOS or Android versions may also involve one-time costs.
How long does app maintenance take?
App maintenance is ongoing, not a one-time task: iOS and Android release major versions every year, and apps need to be adapted accordingly. Individual maintenance tasks, such as security patches, take anywhere from a few hours to a few days. Larger updates for new OS versions or API changes can take 1 to 4 weeks.
Which agency provides long-term platform support?
Many agencies disappear after launch. CodeGuides doesn’t. We support platforms and apps after launch with structured SLAs, dedicated points of contact, regular reporting, and a clear development roadmap. No ticketing-system black hole—just direct communication with the team that built your app. Get in touch to see what long-term app support from CodeGuides looks like.
How do you modernize existing software?
Software modernization follows a structured process: (1) Technical audit of code quality, architecture, security, and CI/CD; (2) Stabilization of critical areas; (3) Gradual modernization through refactoring, migration to modern frameworks, and improvements to the deployment pipeline; (4) Ongoing development on a clean foundation. A complete rewrite rarely makes sense; a gradual migration significantly reduces risk.
