Mobile App Maintenance services in Sydney & Melbourne for React Native and Flutter apps

Mobile app maintenance is the ongoing work that keeps a published iOS or Android app building, passing store review and running on current devices. It includes framework and toolchain updates, App Store and Google Play compliance, dependency and security patching, certificate renewals, crash monitoring and regular releases. Rocket Lab provides it as a fixed monthly plan per app for React Native, Expo and Flutter apps.

A fixed-fee mobile app maintenance plan from an Australian agency costs about A$1,500 to A$5,500 a month, and Rocket Lab's plans are A$1,490, A$2,990 and A$5,490 + GST per app. The common industry benchmark is 15 to 20 percent of the original build cost per year. Ad hoc hourly maintenance from a Sydney or Melbourne agency typically costs A$150 to A$220 an hour, and a Catch-up project for an app left untouched for two years or more usually lands between A$6,000 and A$30,000.

Yes, and most of the apps we maintain were built by someone else. The free health check tells us what we're working with, and the two-week onboarding is where we document it. If the codebase is in genuinely poor shape we'll tell you before you commit to anything.

We fix the cause and resubmit, and on Active and Partner plans a store rejection gets a response the next business day. Rejections are usually caused by an outdated SDK, a missing privacy manifest or data safety form, a permission Apple wants explained, or a policy change on Play, and all of those are covered by the plan.

Yes. Our team ships and maintains all three in production, including Expo managed and EAS workflows, bare React Native with native modules and the New Architecture, and Flutter with platform channels. Ionic and Capacitor apps are also covered; native Swift and Kotlin apps are quoted individually.

Usually, after a health check. If the app is live and reasonably built, it goes straight onto a plan. If it has never had a proper review, or it isn't finished, start with the App Rescue Report (A$2,950 + GST) so the costed fix list comes before the monthly fee.

Because things break at the worst time: a store rejection when you need a hotfix out, or an SDK deadline the week your campaign launches. Hourly work then happens under pressure, on an old toolchain, at rush rates. A fixed fee moves that work to a calm schedule, and in quiet months the platform work still happens: framework bumps, dependency reviews, OS beta testing, certificate renewals.

On Active and Partner, yes, within the monthly allowance. Larger features are scoped and quoted separately, and plan clients get priority scheduling for them. Essential hours are reserved for fixes and compatibility work.

Write access to the repository, a role on App Store Connect and Google Play Console that can upload and submit builds, access to CI and crash reporting if you have them, and a test account. We sign an NDA first, the accounts stay in your name, and we remove our access if you leave.

Everything stays yours: code, store accounts, certificates, CI configuration and the documentation we wrote. After the initial 3-month term you can cancel with 30 days' notice, and we hand over cleanly and walk your next team through it.
