App Maintenance Services That Keep Your App Fast, Secure and Live

Most apps do not fail on launch day. They decay between releases, until an OS update, a security gap or a slow API starts costing you users. Ailoitte is an application maintenance company that monitors, patches, fixes and updates live apps on fixed monthly SLAs, whether we built them or not. Our application maintenance services cover iOS, Android and web apps, plus the backend and APIs behind them.

App maintenance at Ailoitte, in six answers.

What is covered

Our app maintenance services cover monitoring, security patching, OS and device updates, bug fixing, incident response and small enhancements.

How fast we respond

Critical incidents are acknowledged in under 15 minutes and hot-fixed within 24 hours, with every target written into your SLA.

Monthly cost

Cover starts from $1,500 a month for a single-platform app. Most teams spend 15 to 20 percent of the build cost a year.

Who looks after it

A named senior engineer owns your codebase, backed by iOS, Android, web and cloud specialists. No junior bench on production.

Apps we did not build

Most of our maintenance clients come to us that way. A free App Health Check documents the app before we take it over.

What you keep

Your code, credentials, pipelines and documentation stay yours. At exit we run a clean handover, with no lock-in.

App maintenance services, also called application maintenance services, cover...

App maintenance services are the ongoing work that keeps a live application stable, secure and compatible after launch. That covers performance monitoring, security patching, OS and device updates, bug fixing, incident response and small enhancements. Most teams do not need more features. They need someone to own what is already live.

Apps decay even when nobody touches them. Apple and Google ship a major OS every year, libraries go out of date, and both stores keep raising the bar. Since April 2026, every App Store upload must be built with Xcode 26. From 31 August 2026, Google Play updates must target Android 16, and older apps stop appearing to new users on newer phones.

Support and maintenance are two halves of the same job. Support is reactive: someone answers when a user hits a problem. Maintenance is proactive: patching, updating and tuning before anyone notices. Our application maintenance and support services run both under one agreement, for the app, the backend and the release pipeline.

We look after apps we built and, more often, apps we did not. As a mobile app maintenance company that also covers web platforms and the cloud behind them, we keep one SLA and one escalation path for the whole stack. Your code stays yours, under full IP ownership.

Head Of Product, Apna

We brought Ailoitte in when what we had was an idea rather than a product, and they built the first version from scratch. They understood our requirements immediately and built the team we wanted, on time and on budget. Ailoitte was never a one-project supplier for us. We kept them.

We had a concept and no product. Ailoitte built it from the first MVP through to the version that found its market. We ran the engagement on a time-and-materials basis, with their engineers working inside our team rather than at arm's length. Their commitment to quality and attention to detail truly set them apart.

They did not simply build to the specification. Where they disagreed with our technology choices they proposed alternatives with sound reasoning, which we accepted. Commitments were kept almost every time, and where the team hit a blocker they raised it rather than working around it quietly. A great technology partner, and I would recommend them.

Original testimonial

What our application maintenance services cover.

Our application maintenance services cover six work streams under one SLA: the app, the backend and the release pipeline. Not sure which ones you need? Tell us what keeps breaking.

Maintenance that removes tickets, not just closes them.

Maintenance that removes tickets, not just closes them.

Most maintenance vendors sell you a ticket queue. Ours is AI-native: agents watch your crash streams, logs and store reviews around the clock, and senior engineers fix the cause, so the same problem stops coming back.

How we work

How AI-native maintenance catches problems before users do.

Agents do the watching and the repetitive checks. People make every decision that touches production. These four habits are the difference.

  • 01

    Agentic monitoring, not dashboards

    Agents read crash streams, logs and store reviews, link them to recent releases and point to the likely cause, not just the symptom.

  • 02

    Regression tests on every change

    Each patch runs automated device and regression suites before release, so a fix never turns into the next incident.

  • 03

    A named senior owner

    One senior engineer owns your codebase and its history. No rotating strangers and no junior bench learning on your production app.

  • 04

    Governance built in

    Every change is reviewed, logged and traceable, with a rollback ready, so audits use records you already have.

Support levels

Support levels L0 to L3, and what each one covers.

You pay for the response time your product actually needs. Support keeps users unblocked while maintenance keeps the product healthy, and the two run side by side.

Targets are agreed per tier and written into your SLA.

Level What it covers Target and pricing
L0 Self-service Product and technical documentation, FAQs and a searchable knowledge base, kept current as the app changes. Fewer tickets reach the team. Priced as a one-off setup plus upkeep.
L1 Respond Request intake across channels, triage, basic user issues and status updates until each one is closed. Basic issues resolved in under 30 minutes. Per ticket, or inside the retainer.
L2 Maintain Environment and account admin, log investigation, root-cause analysis, configuration fixes and releases. Serious incidents resolved in under 8 hours. Per ticket, or fixed monthly.
L3 Own the code Complex defects fixed in code and database, full patches and hot-fixes, and fixes to custom features. Critical hot-fixes in under 24 hours. Fixed monthly subscription.

Find out what maintaining your app would cost.

Tell us the platforms, the user numbers and the support hours you need. Within 12 hours a senior engineer sends a fixed monthly price and the SLA tier we recommend.

Why teams choose us as their application maintenance company.

Outcomes, not timesheets

A fixed monthly price tied to an SLA. You are buying uptime and stability, not hours logged against a ticket.

Problems found before users

Monitoring flags regressions first, instead of waiting for a one-star review or an angry support email.

Audit-ready by default

Every change reviewed, logged and traceable, under our ISO 27001 certified process, with evidence ready when auditors ask.

No tribal-knowledge risk

We document the architecture and the release process, so knowledge lives in your records, not in one person's head.

One SLA, not five vendors

App, backend, APIs and cloud covered under a single agreement with one escalation path.

Reliability proven at scale

300+ products delivered, 93% of clients back for more work, and rated 4.9 on Clutch and GoodFirms.

Solutions by industry

App maintenance for regulated and high-traffic sectors.

What breaks, and what it costs, depends on the sector. Healthcare apps need HIPAA change control and audit evidence. Fintech apps need PCI-aware patching and fast security fixes. eCommerce apps need to survive sale-day traffic. Logistics apps must keep tracking when networks drop. These are the sectors where maintenance protects the most revenue.

Onboarding

From first call to full cover, in about two weeks.

Setting up application maintenance and support services takes one to two weeks end to end. Urgent security or stability problems are triaged on day one, alongside onboarding.

Stage 01

App Health Check

Days 1 to 3. We audit the code, security, performance and infrastructure, then send a findings list and risk rating that is yours to keep.

Stage 02

Roadmap and SLA

About 5 days. Support hours, levels, response targets, KPIs, escalation paths and the fixed monthly price, all written down.

Stage 03

Handover

About 4 days. Knowledge transfer from your team or previous vendor, runbooks documented, least-privilege access and monitoring switched on.

Stage 04

Delivery

Ongoing. Patches, fixes and compatibility releases every 2 to 4 weeks, each one tested and peer reviewed before it ships.

Stage 05

Reporting and review

Monthly. A KPI report against every SLA target, a quarterly scope review, and cover scaled up or down within 2 to 4 days.

Technologies and tools we maintain and monitor.

The platforms we keep live are below. Behind them, we monitor with Firebase Crashlytics, Sentry, Datadog, New Relic and Grafana. We test with Appium and XCTest, scan with Snyk against OWASP MASVS, and release through GitHub Actions and Fastlane.

Pricing

How much do app maintenance services cost?

App maintenance typically costs 15 to 20 percent of the original build cost each year. We price our application maintenance services as a fixed monthly retainer tied to your SLA. Essential cover for a single-platform app starts from $1,500 a month. Growth cover for both platforms and the backend starts from $3,500. Enterprise cover for regulated or high-traffic apps starts from $7,500.

There are four ways to pay. Per ticket suits L1 and L2 support with changing volume. A fixed monthly fee suits ongoing L3 cover and is the most common choice. Capped time and materials suits bigger enhancements, and a mixed model combines them.

Six factors set your monthly figure, and a free App Health Check tells you exactly which ones apply.

Platforms covered

One platform, both, or the app plus its backend and cloud infrastructure.

Support hours

Business-hours cover (8/5 or 12/5) costs less than 24/5 or 24/7 on-call.

Response targets

Hour-level SLAs on critical incidents need more engineers on standby.

Code health

A well-built app costs less to keep. Heavy technical debt costs more until it is paid down.

Compliance scope

HIPAA, PCI DSS or SOC 2 reporting adds audit evidence and documentation work.

Enhancement allowance

A bigger monthly allowance for improvements means a bigger retainer.

Ways to start

Three ways to start maintenance cover.

Pick the route that matches where your app is today. Each one ends in the same place: a written SLA and a senior owner for your code.

01

Free App Health Check first

A few days of auditing code, security, performance and releases, then a prioritised findings list and a recommended SLA tier.

For when you are not sure what shape the app is in.

02

Fixed monthly SLA

Monitoring, patching, fixes and compatibility releases on a fixed monthly fee, with response targets written down.

For a live app that needs steady, predictable cover.

03

Take over from your current vendor

We coordinate knowledge transfer with your outgoing team, document what is missing and run in parallel so cover never drops. Need extra hands instead? Hire dedicated developers.

For when the people who built it have moved on.

Service transparency

The reports you receive every month.

Numbers you can hand to your board, not a list of closed tickets.

Service level report

Response and resolution times against every SLA target, including any misses and the reason for each.

Incident reports with root cause

What happened on each significant incident, why, and the change made so it cannot happen again.

Security and audit report

Patches applied, CVEs closed, scan results and compliance evidence ready for your auditors.

App health metrics

Crash-free sessions, cold start, API latency, memory use and the store rating trend.

Workload report

Planned against actual effort, so you can see exactly where the retainer went.

Risk register

Open risks and technical debt, with the order we recommend fixing them in.

FAQ

Application maintenance and support services, answered.

How much do app maintenance services cost?

App maintenance typically costs about 15 to 20 percent of the original build cost per year. We price it as a fixed monthly retainer tied to an SLA, so a small app on essential cover starts lower and enterprise apps with 24/7 response cost more. You get the exact figure after a free App Health Check.

What is included in application maintenance and support services?

24/7 monitoring and alerting, crash and performance fixes, security patching and dependency updates, OS and device compatibility releases, incident response within SLA, app store resubmissions, and a monthly report. Small enhancements are included up to an agreed allowance; larger features are scoped separately.

Do you maintain apps you did not build?

Yes, and most of our maintenance clients come to us exactly that way. We start with an App Health Check  that audits the codebase, security, dependencies, and infrastructure, then document everything so there is no tribal-knowledge risk before we take over.

What is the difference between app support and app maintenance?

Support is reactive, responding to user issues and incidents within an agreed SLA. Maintenance is proactive, patching security, updating dependencies, keeping the app compatible with new OS versions, and improving performance before users notice. We provide both under one agreement.

How quickly can maintenance start?

Typically within one to two weeks. The App Health Check takes a few days, then onboarding, access handover, and monitoring setup follow. Critical security or stability issues can be triaged immediately, in parallel with onboarding.

Can you handle both iOS and Android maintenance?

Yes. We maintain native iOS and Android apps, cross-platform React Native and Flutter apps, and the backend and APIs behind them, under a single SLA rather than separate vendors per platform.

Is my code and data secure during maintenance?

Yes. We work under NDA with least-privilege access, encrypted credentials, and no data retention. You keep full IP ownership, and we follow ISO 27001 and SOC 2 practices with documented access controls and audit trails.

What are your response and resolution SLAs?

Critical incidents are acknowledged within minutes and hot-fixed typically within 24 to 48 hours. High-priority issues are resolved in the current cycle, standard items in the next scheduled release. Exact targets are agreed per tier and written into the SLA.

Do you provide a monthly maintenance report?

Yes. Every month you receive crash-free rate, performance and cold-start metrics, security patches applied, incidents and resolution times against SLA, work completed, and recommended priorities for next month.

Can you take over maintenance if our original developers left?

Yes, this is one of the most common reasons teams call us. The App Health Check reverse-documents the architecture, dependencies, and deployment process, so the knowledge lives in documentation rather than in one person’s head.

Do you offer app maintenance for enterprise apps?

Yes. Enterprise cover includes 24/7 monitoring, priority incident response, compliance reporting for HIPAA, PCI DSS, or SOC 2 scope, MDM and enterprise distribution support, and integration maintenance with ERP, CRM, and identity systems.

Can you modernise a legacy app rather than just maintain it?

Yes. Where an app is too dated to maintain economically, we modernise incrementally, migrating from Objective-C or Java to Swift or Kotlin and replacing the weakest layers first, so you avoid a risky full rebuild while cutting maintenance cost.

Do you maintain the backend and APIs too, or only the app?

Both. We maintain the mobile or web client plus the backend, APIs, and cloud infrastructure behind it, because most incidents originate server-side. One SLA covers the whole stack.

What KPIs do you report against?

Typically: first response and resolution time against SLA, crash-free session rate, cold-start and API latency, patches applied and CVEs closed, escaped defects, uptime, and store rating trend. We welcome KPI suggestions and tailor the set per project, then report on the cadence you prefer.

Can we scale the maintenance service up or down?

Yes, typically within 2 to 4 days, via a short addendum to the existing SLA rather than renegotiating the contract. We also run quarterly reviews to check the scope still matches what you actually need.

What support hours can you cover?

We cover 8/5, 12/5, 24/5, and 24/7 depending on tier. Time-zone overlap is agreed at kickoff, and out-of-hours cover uses a documented on-call rotation with named escalation contacts.

Which pricing model should we choose?

Per-ticket suits L1 and L2 support with variable volume, fixed monthly suits ongoing L3 cover and is the most common, capped time and materials suits feature evolution, and a mixed model combines them for long-term partnerships.

Do you take over from an existing maintenance vendor?

Yes, regularly. We coordinate knowledge transfer with your outgoing vendor, document what is undocumented, and run both in parallel briefly if needed so there is no coverage gap during the handover.

What happens if we want to end the maintenance agreement?

You keep everything. All documentation, credentials, pipelines, and code remain yours, and we run a structured handover to your team or your next partner. No lock-in and no retained access.

What are application maintenance services and who needs them?

Application maintenance services keep a live app secure, stable and up to date after launch. They cover monitoring, security patches, OS and device updates, bug fixes, incident response and small improvements, usually under a fixed monthly SLA. Any business with an app real customers depend on needs them, especially after each new iOS or Android release, when the original developers have moved on, or when the app handles payments or personal data. At Ailoitte, cover starts from $1,500 a month for a single-platform app, and critical incidents are acknowledged in under 15 minutes. If someone else built your app, a free App Health Check documents it before we take over.

Have a question about your own app?

Send it with the app name and platforms, and a senior support engineer will reply, usually the same day.

Ask a support engineer

Keep your app fast, secure and always live.

Start with a free App Health Check. You get a prioritised findings report, a risk rating and a recommended SLA tier, with no obligation. Our app maintenance services begin only when you are sure the cover fits.

  • A health check report that is yours to keep
  • One fixed monthly price, never hourly
  • An NDA signed before we see your code
  • Full cover live within one to two weeks
