Mobile App Maintenance Cost

Typical pricing guidance for maintaining, fixing, updating and taking over existing iOS and Android apps.

How Much Does Mobile App Maintenance Cost?

The honest answer is that it depends on the app, the state of the codebase and what you actually need done.

Pricing depends on the technical reality of the project

Some existing mobile apps just need a small fix or a straightforward platform update. Others need investigation, stabilisation, store submission work, backend support or a careful takeover from a previous developer.

Because of that, the cost of mobile app maintenance usually depends on factors such as:

  • how complex the app is
  • whether the issue is a quick fix or a deeper inherited problem
  • whether the app is iOS, Android or both
  • whether the app also depends on a backend or API
  • how urgent the work is
  • whether you need one-off fixes or ongoing support

I am James Thornley, a senior software engineer with over 30 years of development experience and 15 years in mobile development. I work on a freelance, fixed-price or ongoing support basis depending on the project.

Typical Ways I Work

Different types of work suit different commercial arrangements.

Time Basis

Suitable for smaller fixes, technical investigation, debugging sessions or short update work where the scope is still emerging.

Fixed Price

Suitable where the work is well enough understood after review, for example a clearly defined update or a known piece of app rescue work.

Ongoing Support

Suitable for live apps that need regular bug fixing, platform updates, store submissions and general technical support over time.

Typical Engagements

These are the kinds of commercial arrangements that are most common.

  • initial technical review or assessment of an existing app
  • one-off bug fixing or crash investigation
  • update work for new iOS or Android platform requirements
  • rescue or takeover work where the previous developer is no longer available
  • ongoing app maintenance and support

For smaller tasks, it is often sensible to work on a time basis. For larger fixes, inherited projects or update work, I usually prefer to review the app first and then provide a clearer estimate.

What Affects the Cost?

Two apps can appear to need the same thing, but the cost can differ significantly depending on the technical situation.

Complexity

A simple standalone app is very different from a complex app with offline sync, custom business logic and API dependencies.

Handover Quality

If the previous developer is gone and documentation is weak, more investigation is often needed before useful work can begin.

Urgency

Urgent production issues, store deadlines or business-critical outages naturally increase the pressure and required focus.

Backend Dependencies

If the mobile app depends on server-side systems, APIs or data flows, the job often involves more than the app alone.

Typical Pricing Guidance

I prefer to be clear without pretending every project fits into a rigid price list.

As a rough guide:

  • small investigations or focused fixes can often be handled on a short time basis
  • inherited-app debugging usually benefits from an initial review first
  • platform update work may be straightforward or may expose wider technical debt
  • larger app rescue or takeover projects are usually best estimated after a quick assessment
  • ongoing maintenance is often best handled as regular support rather than repeated ad hoc fixes

I do not publish rigid public price points because the right commercial approach depends heavily on the app and the problem. However, I am happy to discuss likely scope and the best way to structure the work.

Why Pricing Is Not Always Fixed Up Front

This is especially true for inherited and legacy app work.

If you are asking someone to fix or maintain an existing app, the biggest unknown is often the current state of the codebase. A problem that sounds simple may turn out to involve store configuration, backend dependencies, outdated libraries, signing issues or undocumented behaviour.

That is why the most sensible approach is often:

  • quick initial discussion
  • short technical review where needed
  • clearer estimate or recommended next step

This reduces the risk of underestimating inherited work and usually gives you a more realistic and useful answer than a made-up flat price.

Mobile App Maintenance Cost FAQ

Common pricing questions for existing app support and rescue work.

How much does mobile app maintenance cost?

The cost depends on the complexity of the app, the urgency of the work, the state of the codebase and whether the need is for one-off fixes or ongoing support.

How much does it cost to fix an existing mobile app?

Smaller fixes may only require a short investigation, while more complex inherited apps or urgent production issues often need a deeper technical review before a realistic estimate can be given.

Do you work hourly, fixed price or ongoing support?

I can work on a freelance, fixed-price or ongoing support basis depending on the project and the clarity of the requirements.

Can you give an estimate after reviewing the app?

Yes. For larger bug fixes, takeovers or update projects, I usually review the app first and then provide a clearer estimate.

Can you keep supporting the app after the initial work?

Yes. Many projects start as a fix or update and then move into ongoing maintenance and support.
