iOS & macOS App Maintenance & Support

OS updates, dependency upgrades, and bug fixes on a predictable schedule. Your app keeps running smoothly long after launch day, without you having to think about it.

A shipped app is not a finished app. Apple and Google each ship a major OS release every year, dependencies go stale, and users report real bugs that never showed up in testing. App maintenance is the ongoing work of keeping an app current and working — the same discipline this studio applies to keeping its own products, like ShiftOS, running through every new macOS release.

The costly version of maintenance is the one nobody does until something breaks: an app that has skipped three OS releases needs a migration project, not an update. Dependencies that were current two years ago now require intermediate upgrades to move at all, and the SDK that stopped being maintained has to be replaced rather than bumped. Keeping pace is cheaper than catching up, and it is far more predictable to budget for.

Apple in particular sets the pace: a beta cycle every summer, a release every autumn, and each one capable of changing layout behaviour, deprecating an API a screen depends on, or tightening a permission prompt. Testing against the betas is what turns a potential launch-week emergency into a routine update shipped before users ever hit it.

What Ongoing Maintenance Covers

OS Compatibility Updates

iOSmacOSAndroid
Testing against each summer beta cycle and shipping fixes before the public release, rather than after users report breakage. Every year brings deprecated APIs, changed layout behaviour and tightened permission prompts — the difference between a routine update and an emergency is when you find out.

Dependency Upgrades

SPMGradle
Keeping packages current in small, reviewable steps, including the Xcode and Swift version bumps that force everything else forward. Upgrading regularly means one changelog at a time; deferring it means a migration project where several breaking changes have to be untangled at once.

Bug Fixes

Reproducefixverify
Real reported issues reproduced against a real device and build, fixed at the cause rather than patched at the symptom, and verified before release. Includes the awkward ones that only appear on a specific OS version or hardware generation.

Crash Monitoring

SentryXcode Organizer
Watching crash and error reporting so regressions surface from telemetry instead of from a one-star review. Crashes are triaged by how many real users each one affects, so effort goes to the ones that actually matter.

Small Feature Work

Scoped per cycle
The steady stream of small changes a live app accumulates: a copy change, an extra setting, support for a new device size, an added share option. Bundled into the regular release rhythm rather than each becoming its own negotiation.

Store Resubmission

App StorePlay Store
Handling the release itself — build, sign, notarize where required, update metadata and screenshots, submit, and respond to review. Including the rejections, which are usually a policy clarification rather than a code problem.

How Maintenance Works

1

Handover

Getting oriented in the codebase, build and release pipeline — including apps originally built by someone else, which most maintenance work is.
2

Baseline

An initial pass on what is already out of date or breaking: stale dependencies, deprecated APIs, and anything currently crashing in the wild.
3

Release Rhythm

A predictable cycle of fixes and upgrades rather than ad-hoc emergency work, so cost and timing are something you can plan around.
4

OS Cycle

Testing against the summer betas each year and shipping compatibility updates ahead of the public release.
5

Reporting

A plain summary of what changed, what it fixed, and what is worth doing next — no jargon wall.

Frequently Asked Questions

Do you maintain apps you didn't originally build?

Yes — taking over maintenance on an existing app starts with actually reading the codebase, not guessing at it, then keeping it current on a predictable schedule.

What does app maintenance actually include?

Keeping up with new iOS/Android OS releases, dependency and SDK upgrades before they become forced, bug fixes reported by real users, and small feature work — the ongoing cost of keeping a shipped app healthy, not a one-time launch fee.

How is maintenance priced?

Scoped per app, same as a new build — based on how actively it needs updates and how many platforms it runs on, not a flat retainer regardless of actual work.

What is the minimum maintenance commitment?

No fixed minimum term — some clients want a single OS-compatibility pass before a new iOS/Android release, others want an ongoing monthly retainer. Scope and cadence get set to match what the app actually needs.

How fast do you respond to a critical bug?

Response time is agreed upfront as part of the engagement — a production crash affecting active users gets prioritized ahead of scheduled dependency updates, and that priority order is explicit, not assumed.

Do you handle both iOS and Android maintenance?

Yes, plus macOS. If the app spans platforms, maintenance covers all of them under one engagement rather than needing a separate contract per platform.

Can you maintain an app built by another developer or agency?

Yes — this is most of what maintenance work actually is. It starts with getting properly oriented in the codebase and release pipeline before making changes, not assuming the previous team’s decisions were wrong.

What happens if you find a bigger problem than expected?

You get told, with the real scope and cost, before work proceeds — not a silent overrun or a surprise invoice. Maintenance work surfaces issues sometimes; how to handle them is your call, not a default upsell.

Do you write tests as part of maintenance?

Where it protects logic that would be expensive to get wrong again, yes — targeted automated tests around the fix, not a blanket coverage mandate unrelated to the actual maintenance scope.

Can maintenance include small new features, not just fixes?

Yes — the steady stream of small changes a live app accumulates (a setting, a copy change, support for a new device size) fits into the regular release rhythm rather than needing its own separate project.

What do you need from me to start a maintenance engagement?

Access to the repository, App Store Connect / Play Console, and a sense of what is currently broken or overdue. A baseline pass on dependencies and deprecated APIs usually happens first, so you know what state the app is actually in.

Need Ongoing Support?

Send over the app and its current state. You'll get an honest read on what is already overdue and what a sustainable release rhythm would cost.
