Introduction

Launching an app or business system is a proud moment. After months of planning, design, development and testing, real customers and staff finally start using it. It is tempting to treat launch day as the finish line.

In reality, launch is the start of the software’s working life, and like any valuable asset, software needs regular care. Phone operating systems release new versions every year. App stores introduce new rules. Security weaknesses are discovered in widely used components. Data grows, users find unexpected ways to use features, and the business itself changes. Software that is not maintained gradually becomes slower, less secure and less useful, until a small problem becomes a crisis.

The good news is that maintenance does not need to be complicated or expensive. A clear routine, the right tools and a reliable support partner prevent most problems before users notice them. This article gives a practical maintenance checklist for mobile apps, web applications and business systems. It covers monitoring, backups, security, platform updates, performance, user feedback and planned improvements, with a suggested schedule and guidance on support plans. It reflects how our team at Dsigngo Group and Raiden (Pvt) Ltd supports software after launch.

The four types of software maintenance

Software engineers often describe four types of maintenance:

• Corrective maintenance: fixing defects found in real use.
• Adaptive maintenance: updating software to keep working with changing environments, such as new operating systems, browsers, devices, app store rules and third-party services.
• Perfective maintenance: improving performance, usability and features based on feedback.
• Preventive maintenance: reducing future problems, for example by updating libraries, improving code quality and removing unused features.

A good maintenance plan includes all four, not just fixing bugs when they are reported.

Tip 1: Monitor everything that matters

You cannot fix what you do not know about. Monitoring tools watch your software continuously and alert the team when something goes wrong.

Monitor:

• Uptime: whether the website, app back end and APIs are reachable.
• Errors and crashes: server errors and mobile app crashes, with details that help developers find the cause.
• Performance: page load times, API response times and database speed.
• Resources: server CPU, memory, disk space and database size.
• Security events: failed logins, unusual traffic and blocked attacks.
• Business events: for example, a sudden drop in orders or payments, which can reveal a hidden technical problem.

Alerts should go to the right people, with clear priorities, so that important issues are not lost among minor notifications.

Tip 2: Back up, and test your backups

Backups protect against hardware failure, mistakes, software bugs and ransomware. Good practice includes:

• Automated backups of databases and uploaded files.
• Copies stored in a separate location from the live system.
• At least one copy protected from deletion or encryption by attackers.
• Retention periods that match business needs, such as daily backups kept for a month and monthly backups kept for a year.
• Regular restore tests. A backup that has never been restored is a hope, not a plan.

Agree how much data the business could afford to lose and how quickly systems must be restored, then design backups to meet those targets.

Tip 3: Apply security updates promptly

Modern software relies on frameworks, libraries, plugins and server software maintained by others. When security weaknesses are found, updates are released, and attackers often begin scanning for unpatched systems soon after.

Keep a list of the components your software uses, monitor security advisories, test updates and apply them promptly. Critical updates may need to be applied within days. For websites built on content management systems such as WordPress, outdated plugins and themes are among the most common causes of hacked sites.

Security maintenance also includes reviewing user accounts, removing access for people who have left, renewing certificates and checking firewall rules. Insights Article 6 explains secure software practices in more detail.

Tip 4: Keep up with Android, iOS and app store changes

Apple and Google release major operating system updates every year, along with new devices and screen sizes. Apps must be tested on new versions and updated where needed.

App stores also change their rules. Google Play requires apps to target a recent Android API level: from 31 August 2026, new apps and app updates must target Android 16 (API level 36), and existing apps must target at least Android 15 (API level 35) to remain available to new users on newer devices. Apple regularly updates its App Store Review Guidelines and requires apps to be built with recent versions of its development tools. Apps that fall behind can be blocked from updating or hidden from new users.

Plan at least one or two compatibility updates each year for every mobile app.

Tip 5: Watch third-party services and integrations

Your software probably depends on outside services: payment gateways, SMS providers, maps, email delivery, courier tracking, accounting software or AI services. These providers change their APIs, retire old versions, update security requirements and adjust prices.

Keep a register of every integration, the account owner, the version used and renewal dates. Subscribe to provider announcements, and test integrations after any change. Many sudden failures, such as payments that stop working, are caused by an expired key or a retired API version.

Tip 6: Renew domains, certificates and accounts on time

Expired domain names, SSL certificates and developer accounts can take an entire system offline. Keep a calendar of renewal dates for:

• Domain names.
• SSL/TLS certificates (many renew automatically, but automation can fail).
• Apple Developer Program membership, which renews annually.
• Hosting accounts and cloud subscriptions.
• Software licences and third-party service subscriptions.

Make sure renewals are linked to company payment methods and email addresses, not a former employee’s personal account.

Tip 7: Keep performance fast

Software often slows down gradually as data grows and features are added. Regular performance maintenance includes:

• Reviewing slow pages and API calls.
• Optimising database queries and adding indexes where needed.
• Archiving old data that is rarely used.
• Compressing images and files.
• Using caching and content delivery networks.
• Checking app start-up time and memory use on lower-cost Android phones.

Users notice speed. Faster software improves satisfaction, conversion and staff productivity.

Tip 8: Listen to users

Users are your best source of improvement ideas. Gather feedback through:

• App store reviews and ratings.
• In-app feedback forms and support chats.
• Support tickets and common questions.
• Analytics showing which features are used and where users drop off.
• Regular conversations with key users and staff.

Group feedback into themes, estimate the value and effort of each improvement and add them to a prioritised backlog.

Tip 9: Plan regular improvements

Successful apps improve steadily. A regular release rhythm, for example monthly or quarterly, lets you deliver bug fixes, small improvements and occasional new features without disrupting users. Each release should follow the same process: development, testing, approval, deployment and monitoring.

Avoid letting improvements pile up into a single large update. Small, frequent releases are easier to test and less risky.

Tip 10: Keep documentation up to date

Every change should be reflected in technical documentation, user guides and administrator instructions. Up-to-date documentation helps new team members, speeds up support and protects your investment if your support partner changes.

Tip 11: Clean up technical debt

Technical debt is the accumulated cost of shortcuts, outdated code and quick fixes. A little is normal, but too much makes every future change slower and riskier. Set aside time in regular releases to refactor difficult code, remove unused features and upgrade outdated frameworks before they reach end of support.

Tip 12: Review data protection regularly

As features change, check that the software still collects only necessary personal data, that access is restricted, that retention periods are respected and that privacy policies are accurate. In Sri Lanka, the Personal Data Protection Act, No. 9 of 2022, as amended in 2025, brings key obligations into force from 1 January 2027, making regular reviews especially important.

Tip 13: Prepare an incident response plan

Even well-maintained software occasionally has problems. What matters is how quickly and calmly the team responds. A simple incident response plan answers these questions in advance:

• Who is contacted first, and how, including outside business hours?
• How are incidents classified? For example, “critical” when customers cannot place orders, “high” when a key feature fails for some users, and “low” for cosmetic issues.
• Who decides whether to roll back a release, switch to a backup system or pause a feature?
• How will users be informed? A short message on the website, in the app or by SMS can prevent hundreds of support calls.
• How is the cause investigated and what will be done to prevent a repeat?

After every significant incident, hold a short review without blame. Record what happened, how it was detected, how long recovery took and what will change. Over time, these reviews make systems and teams far more resilient.

Tip 14: Manage releases carefully

Many outages happen immediately after a new release. Reduce this risk by testing every release in a separate environment that mirrors the live system, using a checklist for each deployment, releasing at quieter times, and keeping a quick way to return to the previous version.

For mobile apps, Google Play supports staged rollouts, which release an update to a small percentage of users first. If crash reports rise, the rollout can be stopped before most users are affected. Apple offers phased releases for automatic updates. These features turn a risky “big bang” release into a controlled, gradual one.

Tip 15: Track the right maintenance measures

Measure maintenance so you can see whether it is working. Useful measures include uptime percentage, number and severity of incidents, average time to detect and resolve issues, crash-free user rate for mobile apps, page and API response times, the number of outstanding security updates and the age of the main frameworks in use. A short monthly report with these figures, plus a list of updates applied and recommendations, keeps owners informed without technical detail.

Tip 16: Plan for end of life

Every technology eventually reaches the end of its supported life. Programming language versions, frameworks, databases and operating systems all have published support periods. Running software on unsupported versions increases security risks and makes future changes harder. Review these dates each year and plan upgrades in good time, ideally as part of regular releases rather than as an urgent project when support has already ended. Sometimes the review also shows that a system has served its purpose and should be replaced. Planning that transition early protects data, users and budgets.

Tip 17: Train new staff and refresh existing users

Software is only as effective as the people using it. Staff change, and new employees often learn a system informally from colleagues, picking up workarounds and missing useful features. Keep short training videos and guides up to date, include system training in staff induction, and run a brief refresher whenever a significant feature is released. Fewer user mistakes mean fewer support requests and cleaner data.

A maintenance schedule you can use

Budgeting for maintenance

Maintenance should be planned and budgeted from the start. Costs typically include hosting and third-party services, monitoring tools, a support plan or developer time for updates, and an allowance for improvements. The amount depends on the size and importance of the software, the number of users and how quickly you want new features.

Many businesses prefer a monthly support plan, which gives predictable costs and guaranteed response times, rather than paying for each issue separately.

Choosing a support plan

When comparing support plans, check:

• Response and resolution times for urgent, high, medium and low priority issues.
• Support hours and how to report issues, such as phone, email, chat or a ticketing system.
• What is included: monitoring, backups, security updates, operating system updates and a set number of improvement hours.
• What is excluded and how extra work is charged.
• Reporting: regular summaries of uptime, incidents, updates and recommendations.

Raiden (Pvt) Ltd already supports IT infrastructure through annual maintenance contracts with defined response times, multiple support channels including phone, remote, on-site, chat, email and a ticketing tool, and the same approach applies to software support.

Illustrative example

The following example is illustrative and does not describe a real client.

A fitness studio launched a booking app two years ago, but no maintenance plan was agreed. After a new version of iOS is released, some iPhone users cannot load the class timetable, and the studio only learns about it from negative reviews. Soon after, the payment gateway retires its old API, and online payments stop working for a weekend.

The studio agrees a monthly support plan. The support team sets up crash and uptime monitoring, updates the app for the latest operating systems, moves to the gateway’s current API and creates a renewal calendar. Monthly releases fix small issues and add a waiting-list feature that members had requested. The next operating system update is tested before release, and members notice no disruption.

Frequently asked questions

How often should an app be updated?

Most business apps benefit from small monthly or quarterly updates, plus compatibility updates when Android and iOS change each year.

What happens if we do not maintain our app?

Over time, it may stop working on new devices, be hidden from new users in app stores, become vulnerable to security risks and fall behind user expectations.

Can you maintain an app built by another company?

Often, yes. We first review the code, documentation, hosting and accounts, then recommend a support approach.

Who should own the hosting and store accounts?

Your business should. This keeps you in control and makes it easier to change support partners if needed.

Is maintenance included after launch?

Defects in the software we deliver are fixed free of charge, with no time limit. Ongoing maintenance, such as updates and improvements, is provided through a support plan.

Conclusion

Uptime, speed and security are not achieved once at launch. They are the result of steady, routine care: monitoring, backups, security updates, platform updates, integration checks, renewals, performance work, user feedback and regular improvements. A clear schedule and a reliable support partner turn maintenance from an emergency into a habit.

Our team supports apps and business systems after launch, so they stay fast, secure and useful as your business grows.
