App Maintenance & Updates – Don't Let Your App Become a Risk
OS updates, store policies, security gaps: What you ignore today costs you users tomorrow.
Professional app maintenance starts at €1,499 per month. This includes ongoing OS and store compliance updates, security patches, performance monitoring, and a dedicated senior developer as your point of contact – with no long-term commitment.
Why App Maintenance Is Not Optional
Every year, Apple and Google change their requirements. Apps that don't keep up disappear from the stores – along with all ratings and users.
Store Compliance: Update or Get Removed
Apple and Google remove apps not updated to current SDK versions. Android requires regular target SDK upgrades, iOS demands compatibility with the latest Xcode releases. Without updates, you lose your app – including all ratings and downloads.
Security: Known Vulnerabilities Are an Open Door
Unpatched security vulnerabilities in Gradle, CocoaPods, or npm dependencies put user data at risk. In regulated industries, this can be business-threatening.
Performance: Stop Gradual Degradation
New Android and iOS versions change memory and battery management. Users uninstall apps that launch slowly or drain their battery – your ratings suffer immediately.

Book a CallIs App Maintenance Right for You?
Your app runs, but nobody takes care of it
Your app was built externally – after launch, nobody is responsible anymore. We take over the technical ownership.
Your previous developer is gone
Freelancer no longer available, agency restructured? Whether Kotlin, Swift, Flutter, or React Native – we take over existing codebases and get up to speed quickly.
You need senior quality without a full-time hire
A full-time developer costs €60,000–90,000 per year. Our app maintenance provides senior-level care at a fraction of that.
Your app must meet regulatory requirements
Healthcare, finance, insurance: We know the special security and compliance requirements from years of practice.
Sounds familiar? Then we should talk.
Book a CallHow Our App Maintenance Works
Assessment & Onboarding
We analyze the current state of your app: technology stack (Kotlin, Swift, Flutter, or React Native), dependencies, build configuration, known issues, and open store requirements. You receive a status report with concrete recommendations.
Maintenance Agreement
Based on the assessment, we jointly define the scope: Which platforms? How often? What response times? Transparent terms, no hidden costs.
Ongoing Support
Your dedicated senior developer handles all maintenance tasks: Kotlin and Swift updates, Gradle and Xcode migrations, dependency upgrades. They know your app and its quirks – no ticket system, no project manager in between.
Reporting
You receive regular updates on completed measures, open items, and recommendations. Transparent and traceable.
That's how professional maintenance works. When do we start?
Book a CallWhat Sets Us Apart from Agencies
No junior touching your app
At traditional agencies, maintenance work often falls to the least experienced developers. With us, a senior developer with 10+ years of experience in Kotlin, Swift, Jetpack Compose, and modern cross-platform frameworks works on your app.
Direct line instead of ticket queue
You speak directly with the developer who knows your app. No intermediary layer of account managers and project leads.
Ongoing care instead of fire-and-forget
Our focus is on long-term maintenance contracts. Your developer knows your codebase, your architectural decisions, and your business requirements.
Transparent pricing, fair terms
You know what you'll pay upfront. No monthly allowance that expires. Clear contracts with no surprises.
Convinced? Your dedicated contact is looking forward to hearing from you.

Frequently Asked Questions
Our monthly maintenance contracts start at €1,499 per month. The exact scope depends on complexity, number of platforms, and desired response times. In a free initial consultation, you'll get an estimate for your app.
Short-term: nothing visible. Medium-term: your app gets removed from the store because it no longer meets current SDK requirements. Security vulnerabilities remain open. Users report crashes on new devices. The cost of remediation is always higher than regular maintenance.
Yes. We regularly take over existing codebases from other developers or agencies. During onboarding, we analyze the code, identify technical debt, and create a realistic maintenance plan.
With active maintenance contracts, we typically respond within 24 hours. The exact response time is defined in the contract. For acute emergencies outside existing agreements, simply get in touch.
Yes. App maintenance doesn't end at the smartphone. API changes, server updates, database migrations, and cloud infrastructure are all part of the picture for us.
That depends on complexity and the technologies used. At minimum, we recommend quarterly updates for store compliance and security patches. Apps in regulated industries or with many dependencies need more frequent attention.
Maintenance and modernization often go hand in hand. If your app is based on an outdated tech stack, we can modernize it step by step – as part of ongoing maintenance or as a standalone project.
A one-time update brings your app up to date – but only for the moment. A maintenance contract ensures your app stays current, secure, and store-compliant on an ongoing basis.
Our app maintenance covers four core areas: Technical maintenance (OS compatibility, dependency updates, build pipeline care), store management (App Store compliance, store listing optimization), bug fixing & monitoring (crash analysis with Crashlytics/Sentry, performance monitoring), and security maintenance (vulnerability scanning, security patches, compliance auditing). Which areas are relevant for your app is something we'll clarify in a free initial consultation.
We regularly scan all software components of your app for known security vulnerabilities and fix them proactively. This includes security patches for encryption, certificates, and token handling, as well as compliance audits against OWASP Mobile Top 10 and BSI guidelines. For regulated industries like healthcare or finance, we know the specific requirements.
A rebuild makes sense when maintenance costs consistently exceed the original development costs or when the app is based on severely outdated technologies. In a free initial consultation, we analyze your app and give you an honest assessment: maintenance or rebuild. Often, apps can be economically operated for years with targeted modernization.
Critical adjustments should happen within 2–4 weeks of a new OS version, as users update quickly and incompatibilities immediately lead to negative reviews. We test your app with beta versions of new OS releases and proactively plan necessary updates – you'll never be caught off guard by a system update.
Many companies suddenly find themselves without a developer – due to job changes, agency closures, or other reasons. We take over such 'orphaned' apps and first create a complete code analysis and access overview. With 10+ years of experience, we can quickly understand and continue unfamiliar code.
We use professional monitoring tools like Firebase Crashlytics and Sentry that capture crashes, load times, and performance issues in real time. You receive regular reports with concrete metrics. For critical issues, you're notified immediately – often before your users even notice.
