App Maintenance Services for Android and iOS Apps

Keep your app live, compliant and crash-free through every Android and iOS release, store policy change and SDK update, with a team that responds quickly when it matters.

App Maintenance & Support

What is App Maintenance & Support?

A mobile app is never finished. Every year, Google and Apple release new versions of Android and iOS that change behaviour, introduce new permissions and deprecate older features. Google Play requires apps to target a recent Android version by annual deadlines, and Apple requires new submissions to be built with recent versions of Xcode and its SDKs. Store policies on privacy, payments, account deletion and data disclosures evolve regularly. Payment, maps, analytics and login SDKs release updates, and older versions stop working. New phone models arrive with different screens and hardware.

Apps that are not maintained run into problems quickly: crashes on new devices, features that break after an OS update, warnings from the Play Console, blocked updates because the app no longer meets store requirements, security vulnerabilities in outdated libraries and a slow decline in ratings. In the worst cases, apps are removed from the store or can no longer be updated in time to fix an urgent issue.

Our app maintenance services keep Android and iOS apps healthy and compliant. We monitor crashes, performance and reviews, update apps for new OS versions and store requirements, upgrade frameworks and SDKs, fix bugs, keep the back end and APIs running smoothly, handle store submissions and deliver small improvements each month. We maintain apps we built and apps built by other teams, starting with a thorough health check and handover, and we work to agreed response times so urgent issues are handled quickly.

Capabilities

App Maintenance & Support capabilities.

Ahead of store deadlines

We track Google Play and Apple requirement changes and update apps well before deadlines, so releases are never blocked.

Crash-free by design

Crash and freeze reports are reviewed continuously, and the most common issues are fixed first, improving stability and ratings.

Ready for every OS release

Apps are tested on beta versions of Android and iOS, so they work on release day when users start updating their phones.

SDKs and libraries kept current

Payment, login, maps, analytics and notification SDKs are upgraded before old versions stop working or become security risks.

Clear response times

Priority levels and response targets are agreed upfront, so critical issues such as login or payment failures get immediate attention.

Full ownership for you

Code, signing keys, certificates and store accounts stay under your organisation’s control, with access documented.

Continuous small improvements

Monthly hours can include enhancements based on user reviews and analytics, so the app keeps getting better.

Guide

What should you know about App Maintenance & Support?

Why do mobile apps need regular maintenance?

Mobile apps sit on top of platforms that change every year and depend on many external services. New Android and iOS versions alter permissions, background behaviour and interface details. App stores introduce new policies and technical requirements. Third-party SDKs deprecate old versions. New devices bring new screen sizes. Without maintenance, an app that worked perfectly at launch gradually breaks, becomes non-compliant or falls behind user expectations.

What are Google Play’s target API level requirements?

Google Play requires new apps and updates to target a recent Android API level, with the required level typically rising each year. Apps that fall behind may be unable to publish updates, and older apps may become less visible to users on newer Android versions. Updating the target level often requires code changes for new permission and background rules. We plan these updates well ahead of Google’s deadlines. Our Android app development team handles the technical changes.

What does Apple require for app updates?

Apple periodically requires that new submissions be built with recent versions of Xcode and the iOS SDK, and introduces new requirements such as privacy manifests, account deletion and updated privacy details. Each year’s iOS release can also change behaviour that affects existing apps. We test on Apple’s beta releases from June, fix issues before the public release in autumn, and keep build tools current so updates are accepted. Our iOS app development team manages these changes.

Which maintenance tasks happen every month?

A typical month of maintenance includes:

  • Reviewing crash, ANR and performance reports and fixing top issues.
  • Reading app store reviews and responding to or logging problems.
  • Checking Play Console and App Store Connect for warnings and policy notices.
  • Applying security updates to libraries and back-end servers.
  • Releasing fixes and small improvements through staged rollouts.
  • Monitoring back-end uptime, API errors and push notification delivery.

Why do SDK updates matter?

Apps rely on SDKs for payments, login, maps, analytics, notifications, advertising and customer support. Providers release new versions for security fixes, compliance changes and new features, and eventually stop supporting old versions. An outdated payment SDK may fail on new devices, and an old analytics SDK may conflict with store privacy requirements. We track SDK versions and upgrade them in a planned, tested way.

How do you reduce crashes and freezes?

Crash reporting tools show which crashes affect the most users, on which devices and OS versions, and the code involved. We prioritise by impact, reproduce issues, fix root causes and add tests to prevent recurrence. On Android, application-not-responding errors are tracked through Android vitals, since high rates can affect store visibility. We measure crash-free users over time as a key health indicator.

Why are signing keys and certificates critical?

Android apps are signed with keys managed through Play App Signing, and iOS apps rely on certificates, provisioning profiles and push notification keys that expire or must be renewed. If signing credentials are lost or controlled by a former developer, updating the app can become difficult or impossible. During handover, we make sure all keys, certificates and store accounts belong to your organisation and are stored securely, and we track renewal dates.

How do you take over an app built by someone else?

Many apps come to us after the original developer or agency is no longer available. We first secure access to the source code, back end, store accounts, signing credentials and third-party services. We then build the app from source to confirm it matches the live version, review code quality, SDK versions and compliance, check crash and review data, and document how the app works. Urgent risks are fixed first, followed by a planned maintenance routine.

Is back-end maintenance included?

An app is only as reliable as the servers and APIs behind it. Maintenance can cover back-end hosting, database health, backups, API performance, security patches, push notification services and integrations with payment gateways and other systems. Where the back end is a larger business system, our software maintenance service can cover it alongside the app.

How are updates released safely?

Each update is tested on a range of devices and OS versions, released first to internal testers, then rolled out gradually through Google Play staged rollouts and Apple phased releases. Crash rates and reviews are monitored during rollout, and a rollout can be paused if issues appear. Feature flags let new features be switched off without a new release.

How do reviews and ratings fit into maintenance?

App store reviews are a direct source of bug reports and feature requests. We monitor reviews, reply where appropriate, identify recurring issues and feed them into the maintenance backlog. Fixing problems users mention publicly, and letting them know, often improves ratings. Our app store optimisation service works alongside maintenance on ratings strategy.

How are support priorities defined for apps?

A typical priority model, with targets agreed per client, looks like this.

  • Critical: app will not open, login or payments fail for many users, or data is at risk.
  • High: a key feature is broken for a significant group of users or devices.
  • Medium: a problem with a workaround or limited impact.
  • Low: cosmetic issues and minor improvements.

Can maintenance include new features?

Yes. Monthly hours can include small enhancements, such as new settings, content changes, improved flows or analytics events. Larger features are estimated separately and scheduled into the roadmap. Keeping a steady flow of improvements avoids the situation where an app becomes outdated and needs an expensive rebuild.

When should an app be rebuilt instead of maintained?

A rebuild may be worth considering when the app uses an abandoned framework, the code is too fragile to change safely, performance cannot be fixed incrementally or the design no longer meets user expectations. Even then, a phased approach often works better than a complete rewrite. We give an honest assessment during the health check. If a rebuild is right, options include native, Flutter or React Native.

Which maintenance mistakes cause app emergencies?

These situations often lead to urgent calls.

  • Missing a Google Play target API deadline, blocking updates.
  • Signing keys or store accounts held by a former developer.
  • Expired push notification certificates stopping notifications.
  • Payment SDKs left outdated until they fail.
  • No crash monitoring, so problems surface only in reviews.
  • Framework versions left years behind.

How is maintenance reported?

Monthly reports summarise crash-free rates, top issues fixed, releases shipped, SDK and OS updates completed, store compliance status, support tickets by priority and response times, review trends and hours used. We also flag upcoming store deadlines and platform changes so you can plan ahead.

How do you test apps across devices during maintenance?

Each release is checked on a representative set of devices: popular budget and mid-range Android phones from different brands, recent and older iPhones, tablets where supported and the newest OS versions. Device clouds extend coverage to models we do not hold physically. Automated tests catch regressions in core flows such as login, search and payment, while manual testing covers new changes and visual details.

How is app security maintained over time?

Security is not fixed at launch. New vulnerabilities are found in libraries, encryption standards change and attackers target popular apps. Maintenance includes updating vulnerable dependencies, reviewing permissions the app still needs, rotating API keys and secrets, checking that sensitive data is stored securely and applying server patches. For fintech and healthcare apps, periodic security testing is recommended.

What drives the cost of app maintenance?

Costs depend on the number of apps and platforms, the framework and code condition, back-end scope, number of SDKs and integrations, release frequency, support hours and response targets, device testing needs and the volume of enhancements. A health check at the start gives a realistic basis for the monthly retainer.

Pricing & engagement

How do pricing and engagement work?

App maintenance runs as a monthly retainer with defined hours, response times and support coverage, after an initial health check and stabilisation phase.
