Our Mobile Maintenance Record in Numbers

Our Mobile Maintenance Record in Numbers

Mobile app maintenance is the ongoing work required to keep a live application functioning correctly after its initial launch. It is not a one-time task. Every change in the operating environment creates a potential breaking point. An iOS update, a new Android version, a deprecated API, or a changed SDK can each break a working app.

What Mobile App Maintenance Is, and What Happens Without It

Most apps require maintenance within three months of launch. Frequency depends on how actively your dependencies change. It also depends on how quickly your user base reports issues.

OS Compatibility Updates

Apple and Google each release one major OS update per year and several minor ones. Each release can introduce breaking changes in how apps handle permissions, background tasks, push notifications, camera access, or UI rendering.

What Happens When App Maintenance Is Neglected

Unmaintained apps do not simply stop improving. They actively break. Each of the problems below typically develops within 12 to 18 months of the last maintenance activity.

01

Crash Rate Increases After OS Updates

When Apple or Google releases a new OS version, a proportion of your users upgrade within the first two weeks. Without testing against the new OS, breaking changes in system behavior reach your users immediately. Crash rates spike. Reviews drop. Users uninstall before the ship fixes.

02

Third-Party Integrations Fail Silently

Payment libraries, analytics, SDKs, and social login providers each follow their own versioning schedule. When they deprecate an API version or change a required parameter, your app continues calling the old endpoint until the call fails. Login stops working. Payments are time out. Analytics data disappears.

03

App Store Compliance Issues

Apple's App Store Review Guidelines and Google Play's Developer Policies update regularly. Apps that miss current privacy manifest requirements or data disclosure standards can be rejected during a submission. They can also be removed from the store with limited notice.

04

Security Vulnerabilities Accumulate

Libraries and SDKs that were secure at launch develop known vulnerabilities over time as security researchers identify weaknesses. If your app still ships a version of a library with a documented CVE, it is carrying a known, fixable risk. Attackers do not need to find the vulnerability themselves. They only need to look it up.

05

Performance Degrades as User Data Grows

Features that loaded quickly when the app had 500 users may load slowly when it has 50,000. Database queries that ran efficiently with a small dataset may time out with a larger one. Performance issues at scale are often invisible during testing.

06

Store Ratings Decline

Users leave one-star reviews for crashes, slow load times, broken features, and login failures. A maintained app addresses these issues before the review is written. An unmaintained one accumulates them. Average store rating affects discoverability on both the App Store and Google Play, which compounds the business impact.

What Neglect Costs You

Crash Rate Increases After OS Updates

When Apple or Google releases a new OS version, a proportion of your users upgrade within the first two weeks. Without testing against the new OS, breaking changes in system behavior reach your users immediately. Crash rates spike. Reviews drop. Users uninstall before the ship fixes.

Book a Maintenance Consultation

Running an app without active maintenance is not a cost saving. It is a deferred expense that arrives as crashes, compliance issues, and lost users.

How We Work

How We Structure a Mobile App Maintenance Engagement

Maintenance engagements are structured around the actual risk profile of your application, not a generic monthly retainer with an undefined scope. Before any ongoing work begins, we conduct a maintenance baseline audit that documents where your app currently stands.

Baseline Audit

We review your app's current OS target versions, dependency versions, crash rate, API integration status, and known open issues. The audit produces a prioritized issue list with severity ratings and effort estimates.

Reactive Maintenance

Reactive work covers issues from user reports, crash alerts, and store review feedback. We triage by severity, reproduce, fix, verify across configurations, and release. Severity 1 issues receive priority response.

Proactive Maintenance

Proactive work covers scheduled activities: OS compatibility testing before each Apple and Google release, dependency reviews, and security scanning against updated CVE databases. It prevents reactive issues from appearing.

Planned Feature Work

If your engagement includes feature additions, we scope each one as a discrete deliverable with defined inputs, outputs, and acceptance criteria, tracked separately from reactive maintenance.

Reporting

A monthly maintenance report covers issues resolved, proactive actions taken, performance trends, dependency update status, and upcoming risks, connecting activity to product health metrics.

Mobile App Maintenance: What the Work Looks Like in Practice

The examples below describe real maintenance scenarios, the technical approach we took, and what the business avoided or recovered as a result.

Retail App Payment Flow Fix

Retail App: Payment Flow Broken by iOS Update

Challenge:

A retail client's iOS app used a payment library that relied on a UIWebView-based authentication flow. Apple deprecated UIWebView in iOS 14 and removed it entirely in iOS 15. Users on iOS 15 could not complete the checkout.

The Solution:

We identified the failing component during OS beta testing and migrated the payment flow to WKWebView, using the payment gateway's updated authentication implementation. The fix was deployed through TestFlight for internal verification before the public release. The client's iOS 15 users received the working checkout before the OS update reached the majority of their user base.

Results:

  • Fix completed and released in the two-week window between iOS 15's public announcement and its general availability
  • Zero user-facing downtime on checkout resulted from the update

Fintech App Security Patch

Fintech App: Authentication Library CVE Required Emergency Patch

Challenge:

A security scan identified a known CVE in the version of an OAuth library used by a fintech client's Android app. The vulnerability allowed token interception under specific network conditions. The library maintainer had published a patched version 60 days earlier.

The Solution:

We updated the library version and audited the token handling flow against the updated implementation. We ran regression testing across Android 10 through 14. The update deployed through Google Play's staged rollout, which let us monitor crash rates in a 10 percent cohort before expanding to full release.

Results:

  • Patched version reached 100% of active users within 72 hours of the staged rollout completing
  • No token interception incidents were reported before or after the patch

Mobile App Maintenance
Across the Industries We Serve

Maintenance requirements differ by industry because the risk profile, user expectations, and regulatory environment differ. Each industry below has specific maintenance considerations that we address as part of the engagement.

All Applications

Why Businesses Choose Mobibiz for Mobile App Maintenance

Our mobile app maintenance is delivered by the same engineers who build mobile applications. It is not a separate support team reading documentation. That matters when a crash requires understanding the architecture, not just reading a stack trace.

Engineers Who Understand the Codebase

Maintenance engineers at Mobibiz build mobile apps in Swift, Kotlin, Flutter, and React Native.

Proactive, Not Just Reactive

We monitor Apple and Google developer announcements, track third-party SDK changelogs, and run OS compatibility testing on beta releases. Most issues we address never reach production because we resolve them during the testing window before the OS update ships publicly.

Platform Coverage Without Separate Teams

One Mobibiz maintenance team covers iOS and Android together. There is no separate iOS support queue and Android support queue with different response timelines. One team sees the full picture of your app's health across both platforms.

Transparent Scope and Reporting

Every maintenance engagement begins with a baseline audit that documents the current state. Monthly reports show what was done, what was found proactively, and what is coming in the next cycle. There is no ambiguity about what the engagement covers.

Security-First Approach

We treat security as a maintenance requirement, not an optional add-on. Dependency vulnerability scanning, authentication flow reviews, and data storage audits are part of the regular maintenance cycle for all engagements.

Flexible Engagement Options

Maintenance retainers are available at different coverage levels depending on your app's complexity, user volume, and update frequency. We also take on one-time maintenance projects for apps that need a specific update or audit without an ongoing commitment.

FAQs

Everything you need to know about working with our mobile app maintenance team.

Your app has users depending on it. An OS update, a deprecated API, or an accumulating crash rate can disrupt that experience before you have time to respond reactively.
