Mobile app maintenance services

App Maintenance and Support Company

An app maintenance company for products we did not build: bug fixes, app enhancement services, and ongoing mobile app support. We take over code from prior teams, AI coding tools, and no-code exports, then maintain, fix, and extend it.

Who this page is for

You already have an app

You are not choosing a partner to invent a product from a blank brief. You need an app maintenance company for software that already exists: mobile application maintenance, app maintenance and support, or mobile app support when the original team is gone. If you need a greenfield build instead, that work sits with a mobile app development company on a different path.

It is broken

Crashes, failed releases, store rejections, or regressions after an OS update. You need triage and stabilisation, not a pitch deck for a rewrite you did not ask for.

It needs new features

The product still matters, but the people who knew the codebase are gone. Feature work has to start from what is there, not from a clean-room fantasy.

The build team is gone

A previous agency, freelancers, or an in-house team moved on. Documentation is thin. Access is scattered. Someone has to own the next release.

Support is undefined

You need ongoing maintenance defined per engagement: what we fix, what we enhance, and what stays under your approval. No inherited free-support claim from a project we did not ship.

What we take over

Inherited code, including AI and no-code

Most agencies decline code they did not write. We accept it for audit, and we maintain it when that is the honest call. Platform work after takeover may connect to iOS app development or Android delivery when a native path is already in place.

Previous agency or in-house team

Codebases left behind when the original builders moved on. We start from repository access and what documentation exists, not from blame.

AI coding assistants

Apps assembled with AI coding tools. Patterns are often uneven. The audit checks consistency, tests, and whether the project can be built again from what is in the repo.

No-code and low-code exports

Apps built on or exported from no-code and low-code platforms. We look at lock-in, what is portable, and whether maintenance inside the platform is viable.

Thin or missing documentation

READMEs that stop at install, missing architecture notes, and tribal knowledge that left with the last developer. The audit surfaces that gap early.

Before a proposal

What an inherited codebase audit looks at

Considerations a client faces when someone new opens the repository. Framed as things commonly found, not as claims about a named past project. Upstream scoping for product definition lives on app and product consulting when the brief is still being written; this audit is for code that already exists.

Test coverage, or its absence

Automated tests that protect regressions, or a codebase where every change is a manual gamble.

Documentation and reproducible builds

Whether a clean machine can produce the same binary from what is in the repo and the notes that came with it.

Dependency currency and known vulnerabilities

Libraries that are years behind, abandoned packages, and advisories that already apply.

Secrets in the repository

API keys, tokens, and credentials committed into history. Common on rushed and AI-assisted projects.

Authentication and authorisation

How sessions, roles, and tokens are implemented, and whether privilege boundaries hold.

Data handling and storage

What is stored where, encryption in transit and at rest, and retention habits that create risk.

No-code lock-in and portability

What can leave the platform, what cannot, and whether maintenance means living inside that constraint.

Pattern consistency

Whether the codebase follows one style or many incompatible layers stacked by successive builders and tools.

Store access and signing keys

Whether App Store, Play Console, certificates, and signing material are available and under your control.

After takeover

Who owns what after we take over

Default split for a maintenance engagement on an app we did not build. Several rows are negotiable in the agreement. No response-time figures and no SLA clocks.

Source repository and branch policy
Own the org or project. Approve who has write access.
Work on agreed branches under your policy. Propose branch rules; you decide.
Release approval and store submission
Final approval to ship. Default: you press submit or explicitly authorise us.
Prepare builds and release notes. Submit only when the agreement says we may.
Store and developer accounts
Own App Store Connect, Play Console, and developer memberships.
Operate through roles you grant. We do not take account ownership.
Third party service accounts and billing
Own analytics, push, maps, payments, and the invoices attached to them.
Use credentials you provide. Flag billing or plan limits that block work.
Production credentials and secrets
Own production secrets. Decide rotation policy.
Receive only what the engagement requires. Prefer your vault over chat paste.
Monitoring and alerting
Own the monitoring accounts and who is on the alert list.
Watch agreed channels during the engagement window. Escalation path is written down.
Security patching and dependency updates
Approve riskier upgrades that change behaviour or cost.
Propose and apply routine patches inside the agreed maintenance scope.
Incident response and escalation
Decide business priority and public communication.
Investigate and fix within the engagement definition. Escalation contacts are named in the agreement.
Backlog priority
Set product priority. You choose what ships next.
Estimate, sequence technical work, and advise on risk. Negotiable shared backlog rituals.
Documentation
Own the living docs in your repo or wiki.
Update runbooks and change notes for work we deliver. Depth of docs is negotiable.

Support coverage, hours, and response expectations are defined per engagement. They are not a sitewide free window and they are not claimed as numbered SLAs here.

How takeover runs

From discovery to ongoing maintenance

Six stages ending where ongoing maintenance begins. No week counts and no prices. Related delivery for net-new product work sits under mobile app development services.

Discovery calls, free

Functional and technical discovery. Mutual NDA first, before we look at code or credentials.

Code and access audit

Repository or export, build path, dependencies, secrets, auth, data handling, store access, and platform lock-in where relevant.

Findings report

Written findings, including whether maintaining is the right call or whether a rebuild is the cheaper honest path.

Scope, proposal, and agreement

Scope document first, then proposal and agreement built on that scope. Commercial terms follow the written findings.

Handover of access and credentials

Roles, keys, and environments you grant under the ownership split. Accounts stay yours.

Stabilise first, then enhance

Stop the bleeding, then add features. Ongoing maintenance continues under the engagement definition you signed.

Honesty first

When a rebuild is the better call

Not every inherited codebase can be maintained economically. Some are cheaper to rebuild than to keep patching. The audit is what determines which situation applies, and the finding is reported either way. We will not sell a maintenance contract on a codebase that should be replaced.

What we look for

Irreproducible builds, missing signing keys, abandoned frameworks, secrets baked into history, or no-code lock-in that blocks required changes.

What you receive

A clear recommendation: maintain, stabilise then enhance, or rebuild. You decide with that written on the table.

If rebuild wins

That is a different engagement. We do not pretend maintenance pricing covers a rewrite.

Mobile app maintenance services

App maintenance and support services

Application maintenance services for inherited iOS, Android, and web app maintenance services needs. Mobile application maintenance covers stabilisation, security updates, store releases, and feature work when the audit says the base can carry it. App development and maintenance for net-new builds sits on the development pages; this page stays on takeover and support.

Stabilise

Bug fixes and crash triage

Reproduce, isolate, and ship fixes for defects that block users or releases. Stabilisation comes before feature ambition.

Secure

Dependency and security updates

Routine patching inside agreed scope, with your approval when an upgrade changes behaviour or cost.

Extend

App enhancement services

Feature work planned against the real architecture, not against a greenfield wishlist that ignores what is already shipping.

Release

Store updates and OS compatibility

Help with builds, review notes, and compatibility work when OS or store rules change. Submission stays under your approval by default.

Access

Handover recovery

Reassemble credentials, store roles, and build paths when the previous team left without a clean exit.

Ongoing

Mobile app support and application support services

Mobile app support & maintenance services defined per engagement: what is covered, who escalates, and how backlog priority is set. Not a blanket free window on code we did not ship.

Live products

Apps we build, maintain, and support

Three live products across grocery, education, and logistics. Shown as shipped work under mobile app maintenance and support, including store listings you can open.

Audit before commercial terms

Free discovery, mutual NDA, then findings that say maintain or rebuild. Proposal follows the written scope.

You keep the accounts

Store, developer, and third-party accounts stay yours. We work through access you grant.

Stabilise, then enhance

Feature work waits until the base can carry it. That order protects users and your reputation.

Support defined per engagement

Coverage is written into the agreement for this takeover. We do not borrow free post-launch language from projects we built ourselves.

Platform continuity

When the inherited app is native, work can continue alongside Android app development practices already in the stack.

FAQ

Frequently Asked Questions

Will you take over an app another agency built?

Yes. This page is for apps we did not build. As an app maintenance company we take over code from a previous agency or an in-house team that has moved on, after a mutual NDA and a code and access audit.

Will you work on an app built with AI coding tools?

Yes. Apps built with AI coding assistants are in scope for audit and, where maintainable, for ongoing fixes and features. The audit looks at consistency, tests, secrets, and whether the build can be reproduced.

Can you maintain an app built on a no-code platform?

Sometimes. We assess platform lock-in, what is portable, and whether export or rebuild is the honest path. Some no-code apps are cheaper to rebuild than to maintain inside the platform constraints.

What access do you need before you can quote?

Enough access for a technical audit: repository or export, build instructions if any exist, store and developer account access where relevant, and credentials for environments you want reviewed. Free functional and technical discovery calls come first under a mutual NDA.

What if the code turns out not to be worth maintaining?

We say so. The audit findings report states whether maintaining is the right call or whether a rebuild is cheaper. The finding is reported either way. We do not force a maintenance engagement onto a codebase that cannot be maintained economically.

Do you sign an NDA before looking at our code?

Yes. A mutual NDA is signed before detailed discussion and before we examine the repository.

Can you add new features, or only fix bugs?

Both, when the engagement says so. We stabilise first, then enhance. Feature work and bug fixes sit in the scope document and proposal after the audit.

What happens to our existing store accounts?

They stay yours. Store and developer accounts remain under your ownership. We work through access you grant. Release approval and store submission defaults are agreed in the ownership split for the engagement.
