How Much It Costs to Maintain a Mobile App Per Year

You launched the app, it went live in the stores, and you figure the big spend is behind you. That's where the real cost begins. Maintaining a mobile app costs, on average, between 15% and 25% of its development value every year, which in LATAM translates to a range of USD 3,000 to USD 12,000 annually for a mid-complexity app. That number isn't optional: an app with no maintenance breaks on its own within 12 to 18 months when the new versions of iOS and Android ship.

Why an app doesn't maintain itself

An app isn't like a printed brochure you produce once and forget. It lives on top of two operating systems that change every year, depends on servers you have to pay for, and serves users who find bugs you never saw in testing. If you don't touch it, it doesn't stay the same: it gets worse.

The three drivers of recurring cost are:

1. External changes you don't control: Apple and Google ship one major version per year (iOS 27, Android 17) and force updates to stay published.
2. Failures that surface in real use: oddball devices, slow connections, data your tests never accounted for.
3. Competitive pressure: if your app doesn't improve, the competitor that does invest runs right over it.

How much it costs to maintain an app: annual breakdown

Here's the detail of the real recurring costs, in dollars and built for a mid-complexity app operating in LATAM in 2026.

Item	Annual cost (USD)	Mandatory?
Apple Developer account	99	Yes (iOS apps)
Google Play Developer	25 (one-time)	Yes (Android apps)
Hosting + backend (server, database)	360 – 2,400	Yes (if there's a backend)
Third-party services (push notifications, maps, SMS)	120 – 1,800	Depending on features
Certificates, domains, SSL	50 – 200	Yes
Bug fixes and support	1,200 – 4,000	Strongly recommended
OS compatibility updates	800 – 3,000	Yes
Improvements and new features (evolutionary)	1,500 – 6,000	Recommended
Estimated total	3,000 – 12,000	—

The low end corresponds to a simple app with little backend; the high end, to a transactional app with active users, payments, and sensitive data. A fintech app or digital wallet hits the ceiling of that range because of its security and compliance requirements.

The costs almost nobody budgets for

These are the ones that show up on the second-year invoice and catch plenty of people off guard:

• Forced OS updates: when a major version of iOS ships, libraries you were using become deprecated. Adapting them adds no visible feature, but without it the app crashes on the new phones.
• Third-party APIs that change or start charging: a maps or payments service changes its pricing or its version, and you have to migrate.
• Hosting costs rising with growth: more users means more server. That's good news, but it has to be budgeted.
• User support: replying to reviews, handling bug reports, and managing the stores also eats up hours.

If you want the full picture before you launch, we wrote a dedicated guide on the hidden costs of developing an app that's worth a read.

Corrective vs evolutionary maintenance

Not all maintenance is the same, and lumping it into a single number muddles the budget.

• Corrective maintenance: fixing what breaks. Bugs, crashes, incompatibility with a new OS. This is the mandatory floor.
• Adaptive maintenance: changes to keep working as the environment shifts. An API that updates, a new store requirement.
• Evolutionary maintenance: adding value. New features, performance improvements, redesigns. It's optional, but the app that doesn't evolve loses users.

The practical rule we use with clients: budget corrective and adaptive maintenance as a non-negotiable fixed cost, and set aside an annual evolutionary fund equal to 10-15% of the initial development so you don't fall behind.

How to cut maintenance costs by design

A good part of the maintenance cost is decided before the first line of code is written. These decisions bring it down in concrete terms:

1. Pick a cross-platform stack: an app in React Native or Flutter keeps a single codebase for iOS and Android instead of two separate teams. The maintenance saving is 30-40%.
2. Clean, tested code: a well-built app costs more upfront but far less per year. Cheap, poorly made apps become unaffordable to maintain.
3. Documentation: if the team that built it leaves nothing documented, the next one charges double just to understand the code.
4. A solid backend from day 1: improvising the backend to "ship fast" is the recipe for expensive maintenance.

That's why, when we do mobile app development at Deepyze, we treat maintenance as part of the design, not as something bolted on afterward.

When a maintenance retainer is NOT worth it

Let's be honest: not every app needs a monthly contract.

• Low-risk internal apps: if it's an internal tool used by ten people and a bug can wait three days, a monthly retainer is wasted money. Pay by the hour when you need to.
• Apps frozen on purpose: a one-off event app or a campaign that dies in three months doesn't justify long-term maintenance.
• Prototypes and MVPs in validation: during the validation phase of a mobile MVP, the focus is learning fast, not stabilizing for production. Formal maintenance is premature there.

For everything else —apps with real users, payments, or sensitive data— the retainer isn't an expense, it's insurance: it guarantees that when something breaks on a Saturday night, there's someone to bring it back up.

How to budget it right from the start

The most expensive mistake is quoting only development and discovering maintenance once the money is gone. Do it like this:

1. Add 20% per year to the development budget as a fixed maintenance line item.
2. Ask them to separate third-party costs (Apple, Google, hosting, APIs) from team hours: they're different line items.
3. Define an SLA: how fast a downtime is handled, during what hours, through which channel.

At Deepyze we develop and maintain mobile apps for companies in Argentina and across LATAM with fixed-price maintenance retainers and a clear SLA, with no surprise invoices in year two. We tell you from day one how much it will cost to maintain, and the team works in your own time zone. Tell us about your case and within 24 hours you'll have a concrete proposal with development and maintenance broken out separately.
