Many businesses plan carefully for building an app and then discover that keeping it running also costs money. Operating systems change every year, devices change, libraries need updates and users ask for improvements. Budgeting for maintenance from the start avoids surprises.
What App Maintenance Includes
Compatibility Updates
Android and iOS release major updates every year. Apps need testing and sometimes changes to work correctly and to meet app store requirements, which periodically require apps to target newer platform versions.
Bug Fixes
Real users find issues that testing missed, especially on the wide variety of Android devices in India.
Security Updates
Libraries, SDKs and backend frameworks receive security patches that should be applied promptly.
Backend and Hosting
Servers, databases, storage and bandwidth grow with users. Monitoring and backups are part of this.
Third-Party Services
SMS, maps, payment gateways, push notifications and analytics may have usage-based charges, and their APIs change over time.
Performance Monitoring
Crash reporting, performance tracking and fixing slow screens.
Improvements
New features, design updates and changes based on user feedback and business needs.
How to Estimate the Budget
A common rule of thumb is to budget a meaningful percentage of the original build cost each year for maintenance, separate from major new features. The actual figure depends on the app's complexity, number of integrations, user volume and how actively you want to improve it.
Maintenance Models
- Monthly retainer: a fixed number of hours for updates and fixes, with priority support.
- Pay as you go: billed per request; fine for very stable apps but slower in emergencies.
- Dedicated team: for apps that are a core product and evolve continuously.
"An app that is not maintained slowly breaks, even if nobody touches the code."
Reducing Maintenance Costs
- Use well-supported frameworks and libraries.
- Write automated tests for critical flows.
- Keep documentation updated.
- Avoid unnecessary third-party SDKs.
- Monitor crashes and fix issues early.
Common Questions
What happens if we stop maintaining the app? Over time, it may stop working correctly on new OS versions, face security issues and eventually be restricted by app stores for not meeting current requirements.
Can a different company maintain our app? Yes, if you own the source code and documentation. The new team will need time to understand the codebase, so good documentation reduces cost.
Should maintenance include new features? It is clearer to separate maintenance from new development. Agree a maintenance scope and plan new features as separate projects or sprints.
A Simple Annual Maintenance Plan
- Before each major Android and iOS release: test the app on beta versions and plan fixes.
- Monthly: review crash reports, apply security patches and update libraries.
- Quarterly: review performance, the cost of cloud and third-party services, and user feedback.
- Yearly: review architecture, remove unused features and plan the next set of improvements.
Writing this plan down, with an owner for each item, turns maintenance from emergency firefighting into routine work.
