The App Is Built and the Developers Have Moved On. Who Looks After It Now?

Quick answer — TL;DR

When there is no one to maintain a finished app, problems build up quietly: expiring certificates, outdated libraries, app store rule changes and small bugs nobody fixes. SpiderHunts takes over ongoing maintenance with monitoring, scheduled updates, a clear queue for fixes and small changes, and documentation that keeps you free to move it elsewhere later.

Launched, and then nobody

The app went live and people use it. Customers book through it, or staff run part of the business on it. The team that built it was a project team: an agency, a contractor, a developer who has since left. Their job ended at launch.

Now small things pile up. A customer reports that password reset emails never arrive. The iOS version gets a warning from Apple about an outdated SDK. Someone wants to add a field to a form, and nobody knows where to start. You are not even sure who would get an email if the server stopped responding.

Why software does not stay finished

An app sits on top of things that keep changing, even when your own code does not.

What changes underneathWhat happens if nobody responds
Operating system and browser updatesLayouts break or features stop working on newer devices
App store requirementsUpdates are rejected, or the app is eventually removed from listings
Libraries and frameworksSecurity fixes stop, and upgrading later gets harder
Third-party APIs (payments, email, maps)Old versions are switched off and features fail
Certificates, domains, keysThey expire, usually on a weekend

Build teams often do not plan for this because it is not part of the build contract. So the app looks finished on launch day and starts decaying the next morning.

What an unmaintained app costs

At first, very little, which is why it gets ignored. Then a payment provider retires an API version and checkout stops. Or a security flaw in a library gets published and your app is running the vulnerable version. Or a small change request that should be simple turns into a big job because the framework is now several major versions behind.

Security is the part people underestimate. Public vulnerabilities in popular libraries are published and then actively scanned for. An app that has not been updated since launch is exactly what those scans look for, and the first sign of a problem may be customer data appearing somewhere it should not.

The staff cost is quieter. People work around the bugs. Enquiries about the app go to whoever is most technical in the office, who then spends an afternoon searching forums.

How we take over maintenance

  1. Take stock. We get access to the code, hosting, app store accounts and third-party services, confirm they are owned by your business, and list everything the app depends on.
  2. Get it building. We set up a local and staging build, because an app that nobody can build cannot be patched when something urgent comes up.
  3. Add monitoring. Uptime checks, error tracking and alerts for things like certificate expiry go to named people, so faults are seen before customers report them.
  4. Schedule updates. Dependencies, frameworks and SDKs are updated regularly in small steps, tested on staging first, instead of in one painful jump years later.
  5. Run a single queue for fixes and small changes. You raise requests in one place, see their status and agree priorities with us.
  6. Keep documentation current. Setup, deployment and the reasons behind changes are written down in the repository, so you are not locked in to us.

How much maintenance an app needs varies a lot. A simple internal tool may need little beyond updates and monitoring. A customer-facing mobile app with payments needs more attention. We look at yours and say which it is.

Day to day, afterwards

When something breaks, someone already knows, and there is a known person responsible for it. Updates happen on a schedule rather than in a crisis. Small improvements your team asks for actually get built. And you have a written record of how the app is put together, so the next conversation with any developer starts from facts.

Is this you?

  • The people who built your app are no longer involved.
  • Nobody would notice quickly if it went down.
  • Change requests have been waiting because there is nobody to do them.
  • You have had warnings from app stores, hosting providers or third-party services that you have not acted on.
  • You are not sure whether the libraries it uses are still supported.

FAQ

Frequently asked questions

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

What drives the cost of maintaining an app?

How many platforms it runs on, how many third-party services it depends on, how far behind its libraries are, and how many changes you want each month. A simple internal tool needs far less than a public app with payments.

Can you maintain an app another team built?

Usually, yes. The first step is an assessment so we know what we are taking on, and we tell you honestly if parts of it need work before they can be maintained sensibly.

Do we have to sign up for a long arrangement?

We would rather agree something that fits the app's real needs and review it, than lock you into a level of support you do not use.

What if the app is badly out of date?

We plan the catch-up separately from routine maintenance, in small tested steps, and explain the risk of each step before we take it.
