Bug Fixes & Stability
We triage crashes and user-reported issues from Crashlytics, Sentry and store reviews, fix the root cause, and ship verified updates through App Store and Play review.
Your app changes environment every month — new OS versions, new dependencies, new store rules. We keep your iOS and Android apps stable, secure and fast after launch, with a written scope before any work begins.

Mobile app maintenance services keep a live app working after launch: OS compatibility updates for each new iOS and Android release, bug fixes, security patches, dependency updates and performance optimization. Codazz maintains apps built by our team or inherited from another vendor, with a fixed-scope monthly plan agreed before work starts.
We triage crashes and user-reported issues from Crashlytics, Sentry and store reviews, fix the root cause, and ship verified updates through App Store and Play review.
Every new iOS and Android release changes APIs, permissions and store requirements. We update your app for each major OS version so it keeps working on the latest devices and passes store review.
We track CVEs in your dependencies and frameworks, patch vulnerabilities, rotate exposed keys, and keep your app aligned with OWASP mobile security guidelines.
We profile startup time, memory and battery usage, tune slow queries and rendering, and right-size infrastructure so your app stays fast as your user base grows.
Maintenance keeps what you have working; feature development adds what you do not. We scope and price the two separately so your monthly plan stays predictable and new features never crowd out fixes.
Maintenance is for any live app: startups after launch, enterprises with legacy apps, and teams that inherited a codebase from another vendor or a departed internal team. We pick up where the previous team left off.

You give us repository access, App Store Connect and Play Console credentials, and your monitoring tools. We audit the codebase, dependencies, store listings and crash data to map exactly what needs attention.
We turn the audit into a written scope: which bugs, which OS versions, which security patches, and how much performance work. You approve a fixed-scope monthly plan before any work starts.
We clear the highest-impact issues first — crashes, security patches and store-compliance blockers — and ship the first update through App Store and Play review.
From there we run a steady cadence: dependency updates, OS compatibility work, performance reviews and a monthly report on what was fixed and what is coming next.
After onboarding, most clients run on a fixed monthly retainer. Compare the three tiers below, or read our app maintenance cost guide.

Ask our teamOur maintenance covers four core areas: OS compatibility updates for each new iOS and Android release, bug fixes for crashes and user-reported issues, security patches for dependencies and frameworks, and performance optimization. We also keep your App Store and Play Store listings compliant with current platform policies.
Yes. A large share of our maintenance work is on apps inherited from other vendors or internal teams. We start with a codebase and store audit, document what we find, and hand you a written scope before any work begins — so you know exactly what you are paying for.
Maintenance keeps your existing app stable, secure and compatible; feature development adds new capabilities. We scope and price them separately so your maintenance budget stays predictable and new features never silently crowd out the fixes that keep your app running.
Cost depends on the size and complexity of your codebase, the number of platforms you ship on, how many third-party integrations need updating, and the level of coverage you need. We quote a fixed scope after the audit — no hourly surprises.
After you share repository and store access, we can complete the initial audit within a week and begin the first maintenance sprint right after you approve the scope. Critical issues found during the audit are flagged for immediate fixing.
Tell us about your app and we will come back with a maintenance scope and a fixed monthly plan — no obligation.
